The FOMi-40 is a high speed sync fiber optic

modem with remote configuration and

monitoring. It supports user-selectable data

rates from 56 kbps to 2.048 Mbps.

The FOMi-40 supports the common fiber optic

wavelengths and connector types, operating

over different types of fiber optic links.

An inband management channel allows the user

to monitor, control and configure the remote

unit using the same fiber links as for data

transmission, with no interference between them.

In tail-end applications, the local FOMi-40

automatically detects the external clock rate and

is locked accordingly. It also updates the remote

unit’s clock rate via the management channel.

This enables synchronization of local and

remote units to the network clock.

The FOM-40 is a high speed, synchronous fiber

optic modem operating full or half duplex over

fiber optic cable. It has selectable data rates

from 56 kbps up to 2.048 Mbps, and a range up

to 100 km (62 miles) using single mode

1550 nm laser diode. The FOM-40 can operate

over single mode or multimode fiber using

850 nm or 1310 nm LEDs, 1310 nm laser diode

or 1550 nm laser diode.

The large variety of interfaces supported by the

FOM-40 facilitates the connection of distant

routers to data services. The Ethernet/Fast

Ethernet bridge modules enable the connection

of remote LANs and VLANs. The FOM-40 extends

these services and connections over fiber optic

cables and performs the hand-off to the SDH/

SONET or IP network.

The FOM-40 features V.54 diagnostics to

perform local analog/digital and remote digital

loopbacks. Loopback commands are controlled

either manually by a front panel switch or via

the DTE interface signals. The front panel switch

generates an internal pseudo-random test

pattern (511) according to the V.52 standard,

for testing end-to-end connectivity.
