DS3/RS232/E1/ETH/V.35 Fiber Modem
"DS3/RS232/E1/ETH/V.35 Fiber Modem" is listed under
Network Communications Category
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.
* 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.
