Connect the receive (RX) port on the module (dark colored post) to
the transmit (TX) port of the remote device.
Use the non-color coded fiber strand.
The LINK LED on the module will illuminate when a connection has been established at
both ends (assuming power is ON). If LINK is not lit after cable connection, the cause may
be improper cable polarity. Swap the fiber cables at the module connector to remedy this
situation.
2.3.4.4 Connecting SC-type or LC-type Fiber Optics (snap-in)
The following procedure applies to installations using modules with SC-type or LC-type
connectors.
When connecting fiber media to SC/LC connectors, simply snap the two square male
connectors into the module’s SC/LC female jacks until the click and secure.
2.3.4.5 Connecting Single-mode Fiber Optics
When using single-mode fiber cable, be sure to use single-mode fiber port connectors.
Single-mode figer cable has a smaller diameter than multi-mode fiber cable (9/125
microns for single-mode versus 50/150 or 62.5/125 microns for multi-mode, where xx/yy
represent the core diameters and the core plus cladding respectively). Single-mode fiber
allows full bandwidth at longer distances and may be used to connect 10 Mb nodes up to
10 Km.
The same connection procedures for multi-mode fiber apply to single-mode fiber
connectors. Follow the steps listed in
2.3.4.3: Connecting ST-type Fiber Optics (twist-lock)
and
2.3.4.4: Connecting SC-type or LC-type Fiber Optics (snap-in)
shown above.
