Multimode Fiber Interface
The ATM cable rules follow the FDDI PMD specification. The optical transmitter and
fiber bandwidth adheres to specification ISO DIS 9314-3 such that a 5 ms exit
response time is achieved after 2 km (6600 ft) of fiber.
MIC or SC duplex connectors are recommended depending on the media module
feature code. This allows single connector attachment and keying if desired.
Transceivers with integrated connectors are used. The transmit and receive cables
cannot be accidentally swapped with a duplex connector.
Each point-to-point connection is independent of the network. The maximum link
length between two ports is shown in Table 15.
