IMPORTANT
Fiber-optic-compatible Cisco gateways and transceiversare
shipped from the factory without fiber-optic modules
installed.
For the relevant unit to have fiber-optic capability, it must be
equipped with a separate XCO-type fiber-optic module.
XCO-standard transceiver modules and XCO-type duplex
fiber-optic connectors can easily be sourced as off-the-shelf
parts. If you experience difficulty in sourcing or ordering fiber-
optic parts or accessories, please contact your local Cisco
Networks representative for assistance.
The terminal assignments for male SFP connectors are as follows:
Terminal 1: Tx (outgoing) line
Terminal 2: Rx (incoming) line
Connecting fiber-optic connectors to SFP modules
Fiber-optic components are extremely sensitive to water, dirt and dust. In
particular, the optical interfaces of these components must not be
contaminated by foreign matter under any circumstances.
Ensure optimal performance of a fiber-optic network by connecting fiber-
optic connectors to XCO-type SFP modules only as shown below:
1.
Do not remove protective covers from any fiber-optic components
until you are ready to connect and seal the components within a
minimal period of time.
2.
Remove the protective cap covering the connection ports of the
SFP module.
3.
Slide the round threaded tube that covers the SFP port connector
back along the fiber-optic cable, until the port connector is fully
exposed (below). Note the locking lugs on the metal port
connector.
