PDH Multiplexer (Fiber Access Devices)( FiberOptic Patch Cords )

Much in the office is used that it relays, the network of optical fiber access,the deposit of the base of the movable telephone, the pagination of thetelephone switchboard, the electrical energy, the agricultural networktransforms, the levels public of security four of the networks, Jin Downing,railroad, conservation of the water, petroleum deposit, bank, networks of thedepartment and communications of the army. With opticalsignals of the E1 group of the transmission of fiber 4 8 16, 24, and one signalof Ethernet of the group 10/100M.
    

Characteristics

3. Proportional a signal of Ethernet of the group (to support the function of flow control of the aid in the VLAN agreement,the aids of the consultative way, Half-duplex, 10/100 can work in thefull-duplex)
3. Proportional orders each E1 to the return to the function to the ring of theend, ray Trajectory this end of the function of theconnection
5. Proportional a connection of telephone on watch of the group (to select)
6. Tress ways of the power supply: - 48VDC, 24VDC and 220VAC
7. Distance of the transmission: 2-120Km
8. Conforms to the requirement of the operation of the levelof the telecommunication, average time of good operation (MTBF) on 70,000 hours
9. Tine the redundant trustworthiness, provides 19 “installation of theshelf or model of the table, the wall that hangs, fillings the card,” the typeof shelf 19 simultaneously must alternate and the direct power supply.
10. Realize the function of the direction of the network of the SNMP
