FOM-T3 and FOM-E3 fiber optic modems from RAD
The FOM-T3 and FOM-E3 fiber optic modems convert T3 / E3 electrical signals into optical signals for transmission over
fiber optic cable to extend the T3 / E3 service range to up to 110 km (68.3 miles). RAD FOM-E3 and FOM-T3 support various optical
850 nm VCSEL and 1310 nm LED for multimode fiber
1310 nm laser for single–mode fiber
1310 nm and 1550 nm long–haul lasers for extended range over single-mode fiber
WDM laser for transmission over a single fiber.
The RAD FOM-E3 and FOM-T3 are compatible with RAD’s DXC, Optimux-34, Optimux-45, FOM-E3/ETH, FOM-T3/ETH. FOM-E3 and FOM-T3 support activation of local and remote loopbacks in compliance with ITU V.54.
Front panel LEDs on the RAD FOM-E3 and FOM-T3 indicate system faults in the electrical and fiber optic circuits.
An alarm relay port transmits the following alarm conditions:
Minor alarm – AIS received at the electrical or fiber optic interface
Major alarm – low level of E3 / T3 electrical input or high bit error rate at the fiber optic interface.
