Detailed Description

Description: E1/V.35 optional fiber optical modem Features: FME-2 is high-speed fiber optic modem with two E1/V.35 interface optional. The two interfaces of FME-2 can be V.35 or E1 (G.703), and also one can be V.35, another is E1 (g.703). The data transmitting rate is from N*64K (N=1-31) to 2048 Kbps. The clock is optional internal, external and slave. To achieve point to point testing, FME-2 can process the diagnosis of some troubles though the switch AL, DL and RL. There are many indicators LEDs on the panel to display work state, such as PWR,RXD,TXD, SYNC, TEST... E1 (G.703) interface comply with ITU-T G.823, G.703 and G.742, it can be impedance balance120ohm (RJ45) or unbalance 75ohm (BNC) The requirements to the fiber can be single mode/multi mode, single core/double core, SC/FC/ST, 2km/20km/40km/60km Power supply: AC 220V or DC -48V. Overview: FME-2 provides two interfaces of E1(g.703) or V.35, and the rate to every transmitting channel of E1 or V.35 can be up to 2Mbps. It was made by ASIC circuitry technology, we can also call it " PDH" Obviously, the advantage of this equipment is reduced the cost. It can achieve fiber to V.35 directly in stead of using the PDH and converter. What's more, the clock (slave) of local FME-2 will automatically follow the clock (internal/external) of remote FME-2 ,so it's very easy to operate.
