Overview
E1 Optic Modem FOM-E1 converts E1 electrical signal into optical data stream for transport over single mode or multimode fiber optic cables. At the opposite end of the fiber, the optical stream is converted back into electrical signals of the appropriate interface such as G.703 & V.35. This fiber optic modem extends the transmission distance up to more than 100Km. The frame format of FOM-E1 is frame/unframe for E1, so it can be used to transmit E1 signal of frame video or unframe video. The modem is capable of transmitting synchronous data with external clock at speeds from 1 Kbps up to 2.048 Mbps (n*64K), the modem can also be set to transmit asynchronous data at speeds from DC up to 64 Kbps. It also has V.54 diagnosis function and inside Bit error rate test equipment which is convenient for the users to carry the self-test. Features * Frame format of E1: frame/unframe * High performance laser equipments, with perfect optic/electric characteristic, guarantee the safety
and stability of data transfer* Data rate: up to 2M,N¡�64kbps£¬(N=1~32)ý* Support CRC-4 alarm function* E1 interface features 75¦¸ and 120¦¸ two types, convenient for field connection* The function that timeslots of remote device auto-follow local device settings can be enabled/disabled
(only for this kind of devices)* Adopting the AGC circuitý* Adopting the DLL technology to reduce the jitter
* Abundant loop back test functions, convenient for detection* Stand alone, 220VAC ,-48VDC and Dual power supply for optional
* Suooprt SNMP network Management
