DS3/RS232/E1/ETH/V.35 Fiber Modem

PDH-based, Global Tech GP6 series Fiber Modem provides conversion between electrical and optical signals and transforms one V.35/Ethernet/E1 signal on Single/Multi Mode Fiber. The user can customize the wavelength, connector and data bit rate, from 64kbps to 2,048kbps. GP6 can transfer the in-band management info over different optical fiber link, and monitor and control the local and remote end units. Specification * Sophisticated LED indicators. * Support N* 64K, N=1~ 32, timeslot multiplexing. In framing mode, the local end can configure the remote end bit rate. * Provided 3 types of loopback function, as ANA, DIG and REM, easily installation and maintenance. * V.35 Fiber Modem can interwork with E1 Fiber Modem and Ethernet Fiber Modem directly, and save one E1/V.35 or E1/Ethernet converter cost. * Standard SNMP management interface can monitor all local and remote end units through IP network.
