E1, T1 Fiber Optic Modem

RAD's FOM-E1 or T1 fiber optic modem converts E1 or T1 signals into optical signals, and then transmits the converted signal over a fiber optic cable for extended distances, forming a secure link for data communication devices. Operating at user-selected rates, the FOM-E1 or T1 fiber optic modem can transmit both framed and unframed E1 or T1 signals. The FOM-E1 or T1 fiber optic modem supports different fiber optic interfaces and can operate with several grades of fiber optic cable.

• Extends the range of equipment with electrical E1 or T1 interfaces over fiber optics; up to 144 kilometers (89.4 miles)

• WDM supported, reducing access costs

The FOM-E1 or T1 fiber optic modem converts an E1 or T1 electrical signal into an optical signal. After the conversion, the signal is transmitted over fiber optic cable, extending the E1 or T1 service range up to 144 km (89.4 miles).

 

The FOM-E1 or T1 is transparent to E1 or T1 framing (G.704), which enables it to transmit both framed or unframed E1 or T1 signals.

 

Using the FOM-E1 or T1 opposite the DXC cross connect system, Megaplex access multiplexer or FCD access unit reduces the cost of the fiber optic link when accessing the SDH/SONET network.

 

The FOM-E1 or T1 supports various optical interfaces:

- 850 nm for multimode fiber

- 1310 nm for single mode or multimode fiber

- 1550 nm laser diode for extended range over single mode fiber

- WDM for single fiber extension

 

FOM-E1 or T1operation complies with ITU G.703, G.921 and G.956 standards. The modem supports activation of local and remote loopbacks in compliance with the ITU V.54 standard.
