FOIRL, 10Base-FL Wiring Specifications
The IEEE FOIRL standard limits a fiber segment length to 1 km (1,000
meters or 3,280 feet). That is, the fiber optic cable that connects two
repeaters is limited to 1 km (3,280 ft.).
While the more recent IEEE 802.3 10Base-FL standard is compatible with
FOIRL, it can travel up to 2 km. (2,000 meters or 6,560 feet) using
multimode duplex fiber optic cable in a point-to-point link which directly
attaches two devices. Note, however, that the 2 km. distance only applies
to topologies in which one 10Base-FL node connects to another 10Base-FL
node.
That is, you can intermix 10Base-FL and FOIRL nodes, but if the cable
connects a 10Base-FL node at one end and a FOIRL node at the other, the
limitation would revert to the lesser distance of 1 km (3,280 ft.).
Duplex Fiber
Optic Cable
Both 62.5/125 micron and 50/125 micron duplex optical fiber cable is
supported. Duplex refers to support for fiber optic cable pairs: a two-cable
fiber optic connection with transmit mode dedicated to one cable and
receive mode on the other.
Normally, duplex fiber optic cable is labeled TX or TD (transmit) and RX or
RD (receive). You must connect the receiving port (RX or RD) on one device
to the transmitting (TX or TD) port on a second device for proper
connectivity.
To connect a network device to a fiber optic port on the AT-4016F:
1.
Attach both connectors at one end of the cable to the TX and RX ports
on the network device.
2.
Connect one of the paired connectors at the other end of the cable to the
RX port on the repeater.
3.
Check for On Line indicator to illuminate. If it does, connect the other
of the pair to TX. If On Line stays off, unplug the connector from RX
and use the other of the pair.
