E1 Fiber Optical Modem

Overview: contact: amily[at]veecom dot com dot cn 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" Feaures: 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. DIMENSIONS: 240mm*215mm*50mm (L*w*H)

Fme(fiber optic modem) Detailed selling lead description Fme is high-speed fiber optic modem with remote configuration based on asic circuitry technology. It supports user-selectable rates between n*64kbps (n=1--31) and 2048 kbps. The fiber interface is sc (single module).Transmission distance is up to 60km. The product fully conforms to part 15 of fcc regulation. With remote configuration, the fme rate of user terminal follows the configuration of the fme of master terminal automatically without any other setup. Data interface of fme can be v.35/v.24/rs232 or g.703. E1 rate supports framed mode and unframed mode, which are known as n*64 kbps (n=1--31) and transparent 2048 kbps. External clock, internal clock, and slave clock are supported. With the function of integrated diagnosis, it can perform tests of local analog loop back and remote digital loop back to achieve end-to-end integrity test.
