Introduction
HPOM-4E1-4ETH-XX multiplexer is state-of-art 4 x E1 G.703 + Ethernet 10/100BaseT fiber multiplexer with logical bandwidth control, QoS, and dot1Q VLAN& 39;s which allows effective transmission of those protocols over fiber optical cable over distances more than 120 km.
HPOM-4E1-4ETH-XX can provide up to 4 E1 interfaces and 4 Fast Ethernet interface. The Ethernet interface can be operated in 10M/100M, half duplex or full duplex mode by either auto-negotiation or manual setting.
HPOM-4E1-4ETH-XX is a fiber media transport for 4 E1 + 4 x 10/100BaseT transmission. while the RJ-48C model provides balanced 120 Ohm connections over twisted pair wiring,it provides an order-wire for which a standard telephone can be used.
HPOM-4E1-4ETH-XX provides a user RS232 transparent data link with a RJ45 connector which possesses complete operation monitoring function. Those indicators include Loss of optical signal, LOF, 10-3, 10-6 bit error rate, Loss of each E1 tributary signal and Ethernet status. Since some overhead bytes are taken as monitoring channel, all alarm and status of Remote can be display locally.
