Chapter 1. Introduction to Passive Optical Network

A passive optical network (PON) or Gigabit Passive Optical Network (GPON) is a point-to-multipoint (P2MP) network that uses a combination of active transmission equipments and passive cable components to provide network connectivity to end user's devices. This network is suitable for building access networks such as fiber-to-the-home (FTTH), or fiber-to-the-office (FTTO), or fiber-to-the-company (FTTC) for providing internet access by running fiber optic cable directly from an internet service provider to a user's home or business. The PON technology is based on the ITU-T G.984 standard.

PON transmits Ethernet, Asynchronous Transfer Mode (ATM), and Time Division Multiplexing (TDM) traffic. It consists of mainly two active transmission equipments, Optical Line Terminal (OLT) and Optical Network Terminal (ONT). One of the main characteristics of PON is the use of passive optical splitters in the fiber distribution network, enabling a single feeding fiber from the service provider’s central office to serve multiple homes and small businesses.

The network path between the terminals is known as Optical Device Network (ODN), which comprises passive optical components, such as optical fibers and passive optical splitters. The ODN provides optical channels that interconnect the OLT to the ONTs. The optical fiber cables cover a distance of 20km to 30km.

A single optical fiber from the OLT connects to a passive optical splitter that is located near an end user's premises. The optical splitter divides optical power into n separate paths to end user. The number of optical paths can vary from 2 to 128. From the optical splitter, a single-mode fiber strand is connected to each end user's devices. Data is broadcast in the downstream direction and transmitted in the TDMA mode based on timeslots in the upstream direction.

Components of GPON

The data, voice, and video signals of an end-user devices are sent to ONTs. The signals are converted into GPON Encapsulation Method (GEM) frames and then transmitted over optical fibers to the OLT using the PON uplink ports on the ONTs. On the OLT the GEM frames are converted into Ethernet packets and are forwarded to the upper-layer IP network using the uplink port on the OLT.

Cisco Catalyst PON Series OLT Overview

The Cisco Catalyst PON Series OLT is an aggregation device that is located at a service provider's central office of the PON network. The main functions of a Cisco Catalyst PON Series OLT are traffic scheduling, buffer control, and bandwidth allocation. The Cisco Catalyst PON Series OLT manages the network traffic that is in the form of video, data, and voice signals in a PON network, and sends them downstream to the Cisco Catalyst PON Series ONTs on the network. The Cisco Catalyst PON Series OLT also receives the signals from the Cisco Catalyst PON Series ONTs located at an end user's premises and sends them to their destination over the internet.

A Cisco Catalyst PON Series OLT can support up to 128 Cisco Catalyst PON Series ONTs per port. A Cisco Catalyst PON Series OLT provides 8/16xPON ports, 4xG combo ports and 2x10G small form-factor pluggable (SFP+) ports for uplink. A Cisco Catalyst PON Series OLT carries abundant services and flexible network mode over one optical network, and is especially suitable for networks such as enterprise LAN, video application, and high-speed internet.

Installing SFP or SFP+ Modules

Each Cisco module has an internal serial electrically erasable programmable read-only memory (EEPROM) that is encoded with security information. This encoding provides a way for Cisco to identify and validate that the module meets the requirements for the switch.

For information about installing, removing, cabling, and troubleshooting SFP modules, see the module documentation that is shipped along with your device.

- Installing an SFP or SFP+ Module

- Removing an SFP or SFP+ Module

Installing an SFP or SFP+ Module

Before you begin

When installing SFP or SFP+ modules, observe these guidelines:

- Do not remove the dust plugs from the modules or the rubber caps from the fiber-optic cable until you are ready to connect the cable. The plugs and caps protect the module ports and cables from contamination and ambient light.

- To prevent ESD damage, follow your normal board and component handling procedures when connecting cables to the devices.

Caution

Removing and installing an SFP or SFP+ module can shorten its useful life. Do not remove and insert any module more often than is necessary.

Procedure

Step 1

Attach an ESD-preventive wrist strap to your wrist and the other end to a bare metal surface.

Step 2

Find the send (TX) and receive (RX) markings on the module top.

Note

On some SFP or SFP+ modules, the send and receive (TX and RX) markings might be replaced by arrows that show the direction of the connection.

Step 3

If the module has a bale-clasp latch, move it to the open, unlocked position.

Step 4

Align the module in front of the slot opening, and push until you feel the connector snapping into place.

Step 5

Close the module's bale-clasp latch.

Step 6

Connect the SFP cables to the modules.

Step 7

Store the dust plugs in a safe location.

Removing an SFP or SFP+ Module

Procedure

Step 1

Attach an ESD-preventive wrist strap to your wrist and the other end to a bare metal surface.

Step 2

Disconnect the cable from the SFP or SFP+ module. For purposes of reattachment, note which cable connector plug is send (TX) and which is receive (RX).

Step 3

Insert the dust plugs into the optical ports of the SFP or SFP+ module to keep the optical interfaces clean.

Step 4

If the module has a bale-clasp latch, pull the bale out and down to eject it from the module. If the latch is obstructed and you cannot use your finger, use a small flat-blade screwdriver or any other long and narrow instrument to open the latch.

Step 5

Grasp the SFP or SFP+ module, and carefully remove it from the module slot.

Step 6

Place the module in an antistatic bag or any other protective environment.

Establishing the System Ground

This section describes how to connect a system ground to the OLT.

Caution

Installations that rely solely on system grounding using only an AC third-prong ground, run a substantially greater risk of equipment problems and data corruption than those installations that use both the AC third-prong ground and a properly installed system ground.

The system ground provides additional grounding for EMI shielding requirements and grounding for the low voltage supplies (DC-DC converters) on the modules. You must observe the following system grounding guidelines for your chassis:

- You must install the system ground connection with any other rack or system power ground connections that you make. The system ground connection is required if FXS modules are installed or if this equipment is installed in a U.S. or European Central Office.

- You must connect both the system ground connection and the power supply ground connection to an earth ground. The system ground connection is required if FXS modules are installed or if this equipment is installed in a U.S. or European Central Office.

- When using DC-input power supplies, you must install the system (ground before you attach the source DC power cables to the DC PEM. Power down the chassis before attaching the system ground.

Note

In all situations, grounding practices must comply with Section 250 of the National Electric Code (NEC) requirements or local laws and regulations. We recommend a 6-AWG grounding wire from the chassis to the rack ground or directly to the common bonding network (CBN). The equipment rack should also be connected to the CBN with a 6-AWG grounding wire.

The system ground serves as the primary safety ground for chassis that is equipped with DC-input power supplies. The DC-input power supplies for these chassis do not have a separate ground.

- Required Tools and Equipment

- Connecting the System Ground

Required Tools and Equipment

To connect the system ground, you need the following tools and materials:

- Grounding lug: When using the double-hole lug connector provided with the system, the ground wire must be 6-AWG only. Otherwise, a supported closed-loop ring connector must be used for 8-AWG to 14-AWG wire.

- Grounding screws: One M4 x 8 mm (metric) pan-head screws. Supplied as part of the accessory kit.

- Grounding wire: Not supplied as part of the accessory kit. The grounding wire should be sized according to local and national installation requirements. For U.S. installations, AC power supply systems require a 14-AWG copper conductor. We recommend a commercially available 8-AWG to 14-AWG wire. The length of the grounding wire depends on the proximity of the switch to proper grounding facilities.

- No. 1 Phillips screwdriver.

- Crimping tool to crimp the grounding wire to the grounding lug.

- Wire-stripping tool to remove the insulation from the grounding wire.

Connecting the System Ground

To establish an earth ground for the chassis, you must attach a grounding cable from the OLT grounding lug to the rack.

Chapter 4. Troubleshoot

- Troubleshooting Common Issues

- Cisco Catalyst PON Series OLT Troubleshooting

- Cisco Catalyst PON Series ONT Troubleshooting

Troubleshooting Common Issues

The following section provide information about how to troubleshoot common issues in the Cisco Catalyst PON Series Switches.

- Bad or Damaged Cable

- Ethernet and Fiber-Optic Cables

- Link Status

- 10/100/1000 PoE+ Port Connections

Bad or Damaged Cable

Always examine the cable for marginal damage or failure. A cable might appear physically good, but it could corrupt packets as a result of subtle damage to the wiring or connectors. You can identify this situation because of packet errors occurring at the port or the port constantly flapping.

Perform the following checks on the cable:

- Examine or exchange the copper or fiber-optic cable with a working cable.

- Look for broken or missing pins on cable connectors.

- Rule out any bad patch panel connections or media convertors between the source and the destination. If possible, bypass the patch panel, or eliminate faulty media convertors (fiber-optic-to-copper).

- Test the cable in another port or interface, if possible, to identify if the fault is with the cable.

Ethernet and Fiber-Optic Cables

Make sure that you have the correct cable for the connection:.

- For Ethernet, use Category 3 copper cable for 10 Mbps UTP connections. Use either Category 5, Category 5e, or Category 6 UTP for 10/100/1000 Mbps connections.

- For fiber-optic cables, verify that you have the correct cable for distance and port type. Ensure that the connected device ports match and use the same type of encoding, optical frequency, and fiber type.

- For copper connections, determine if a crossover cable was used when a straight-through was required, or the reverse. Enable auto-MDIX on the device, or replace the cable.

Link Status

Verify that both sides have links. A single broken wire or a shutdown port can show the link that is established on one side even though the other side does not have a link.

A port LED that is in ON status does not guarantee that the cable is fully functional. The cable might have encountered physical stress that causes it to function at a marginal level. If the port LED does not turn ON, do the following:

- Connect the cable from the field device to a functioning good device.

- Ensure that both ends of the cable are connected to the correct ports.

- Verify that both devices have power.

- Verify that you are using the correct cable type.

- Check for loose connections. Disconnect the cable and reconnect it if it is not seated properly.

10/100/1000 PoE+ Port Connections

If a powered device that is connected to a PoE+ port does not receive power, do the following:

- Verify that the power supply installed in the OLT meets the power requirements of your connected devices.

- Verify the cable type.

Caution

Noncompliant cabling or powered devices can cause a PoE+ port fault. Use only standard or compliant cabling to connect Cisco devices. You must remove any cable or device that causes a PoE+ fault.

Cisco Catalyst PON Series OLT Troubleshooting

The following sections describe how to troubleshoot issues relating to the Cisco Catalyst PON Series OLT.

- SFP and SFP+ Module

- Fan Module

- Power Supply Module

- Interface Indicator

- Finding a Cisco Catalyst PON OLT Serial Number

SFP and SFP+ Module

Use only Cisco SFP or SFP+ modules. Each Cisco module has an internal serial EEPROM that is encoded with security information. This encoding provides a way for Cisco to identify and validate that the module meets the requirements for the switch.

You can perform the following checks:

- Inspect the SFP module. Exchange the module with a functioning module. Verify that the module is supported on this platform.

- Use the show interfaces command in privileged EXEC mode to see if the port or module is error-disabled, disabled, or shut down. Reenable the port, if needed.

- Make sure that all fiber-optic connections are free of dust and impurities, and are securely connected.

- Make sure that you keep an interval of 5 seconds between inserting SFPs in multiple device ports. This prevents the ports from going into error disabled mode. Similarly, after you remove an SFP from a port, wait for 5 seconds before reinserting it.

Fan Module

An alarm notification sent through the Cisco Catalyst PON Manager when a pluggable fan module is faulty.

Make sure you replace the fan module within the following time period:

- Replace the fan module within one week if one alarm notifications occur in the Cisco Catalyst PON Manager.

- Replace the fan module within 24 hours if two alarm notifications occur in the Cisco Catalyst PON Manager.

- Replace the fan module within 5 minutes if three alarm notifications occur in the Cisco Catalyst PON Manager.

To replace the fan module, see Fan Module Overview.

Power Supply Module

The PWR1 and PWR2 LEDs indicate whether the power supply module is faulty.

For details about the LED indicators of the pluggable power supply module, see Table 1

If the power supply is faulty, check the following:

- Check if the pluggable power supply module is turned on.

- Check that the power cable is properly connected.

- Check if the input power matches the power ratings of the Cisco Catalyst PON Series OLT.

- Make sure that the Cisco Catalyst PON Series OLT is operating within its permissible operating temperature. If not, move the Cisco Catalyst PON Series OLT to a location where there is proper ventilation.

Interface Indicator

The LINK LED indicates whether the connection is faulty. If the LINK LED is not turned on, do the following:

- Check whether the fiber optic connection is reversed.

- Check whether the optical module is damaged.

Identifying a Crossover Cable

To identify a crossover cable, compare the two modular ends of the cable. Hold the cable ends side by side, with the tab at the back. The wire connected to the pin on the outside of the left plug should be a different color from the wire that is connected to the pin on the inside of the right plug.

Identifying a Crossover Cable

Console Port Adapter Pinouts

The RS-232 console port uses an 8-pin RJ-45 connector. Use an RJ-45-to-DB-9 adapter cable to connect the switch console port to a console PC. You must provide a RJ-45-to-DB-25 female DTE adapter to connect the switch console port to a terminal.
