E1 G.703 fiber optic network modem

E1 G.703 fiber optic network modem
Product Detailed
Extended transmission range up to 100Km Single mode or Multi-mode is optional Three year warranty ISO certified

GQ7001  E1 (G.703)Fiber Optical Modem


        GQ7001 E1 fiber optic modem converts E1 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 modes, the  fiber optic modem can transmit framed or unframed E1 signal.

         The primary application for the E1 fiber optic modem is to establish point-to-point fiber link at ranges longer than any copper modem can achieve.

GQ7001 fiber optic modem supports different fiber optic interfaces and can operate with several grades of fiber optic cable, the equipment to interoperate over GQ7003 V.35 fiber modem and  GQ7002 Ethenet fiber modem
