Connecting fiber optic cable to J2 or J3 ports on Metro-Switch
This section explains how to connect external Ethernet fiber ports to the Metro-Switch
when using standard fiber optic cables. Typically 50 or 62.5 micron multimode fiber
optic cables with LC type connectors are used for 1000 Base SX operation depending
on the connector option. For extended distance, single-mode fiber can be used in
models equipped with extended range single-mode connectors (1000 Base LX).
Insert the fiber optic cable into the LC type connector until the self-locking tab clicks into
position. Connect the opposite end in to a 1000 Base SX switch. Two types of cables
are used when connecting external ports to the Metro-Switch. A workstation or "straight
through" cable is typically used to connect Ethernet fiber ports to switches. A fiber
“crossover” cable may also be used to connect ports back-to-back. This configuration is
useful for loopback and/or diagnostic purposes or when a switch is not available.
