Optical Transceiver Removal and Replacement
Your troubleshooting and diagnostics might reveal that the optical transceiver
component of a GbE optical physical interface card needs to be replaced. The optical
transceiver serves two functions:
•
Converts electrical signals into optical signals used to communicate with other
optical networking equipment.
•
Serves as the receptacle for the LC duplex fiber optic connectors.
Optical transceivers are hot swappable and may be replaced while the Acme Packet
4500 is powered on. Leave the NIU in the Acme Packet 4500 as you extract the
optical transceiver.
To obtain a replacement optical transceiver, contact your Acme Packet sales
representative directly or by E-mail at tac@acmepacket.com.
