PDH мультиплексор оптического волокна

OutLine Standard type: SCP-120 series of standard type can whole transmit transparently 2M Quasi-synchronous based groups signals to achieve voice and data transmission operations.It delivers the capacity as 4 E1 access , and an additional 1 to 4 RS232 asynchronous data access and 1 PCM Official calls access off 2M access. Ethernet type: The scp-120 series can provide ethernet optical transmission system.It makes true the 4 E1 electric circuits and 1-2 100M speed ethernet data passages in mixed use and the optical transmission in a simple and direct and single plank form. Two-fiber protection type: The scp-120 series can provide two-fiber protection type optical transmission system that use optical road 1+1 backup protection, cut over lines automatically,reduce the postpone time because of breakdown. Single-fiber type: The scp-120 series can supply single-fiber type optical transmission system,integrated modular optical transceivers.It can use the resource effectively in case of the fibre resource in short supply. Technical parameters Standard type/Ethernet type: --whole dynamic range adjustment ,open in no distance --Transmit 0-60 km without relay --High integration level,small in size,low power consumption --Excellent anti-jamming capabilities,pass the examination of EMC --Provides 4 E1 transparent transmission, while providing 1-2 100M ethernet accesses --The optical line velocity is 150Mbps --E1 interface code for the type HDB3 Codes,Built-in digital E1 smoothing phase locked loop and clock recovery circuit complies with ITU-T G.823 and G.742. --Supports 1-2 ethernet interfaces,auto-negotiation on half/full duplex mode and 10/100Mbps dual . --Supports VLAN Trunk and flow control --A comprehensive alarms function,and easy for surveillance --Support E1 Link remote circular functions, ease of equipment testing and management --Ordinary telephone for official use --As far-end equipment,it can combine to the center-type equipment and form a star-type net. --Provide RS232 / Ethernet /E1 network interface --Provide 1 RS232 access. --Whole sets of plank design,standard 1U height,19 inch machine box --Optical interface supports ALS(Automatic Laser Shutdown/Reduction) function(please indicate before ordering) --Power supply: AC 220V or DC -40V is available, we can supply dual power It could also provide the following functions: Two-fiber protection type --Optical interface 1+1 backup protection;optical interface switch by hand/automatically when malfunction occurs function can be choosed. Single-fiber type --A single fiber can complete the data transmission,it saves fiber resource effectively. These types of equipment are all with network management interface and network management functions Related products --SCP-120s --SCP-120En --SCP-120G --SCP-120k
