Compact CWDM Optical Transmission System

Description

CWDM is serve to meet the demand of rapid growth of transmission bandwidth.Active CWDM system utilize standard coarse wavelength division multiplexing technology, it can transmit different optical signals on an existing optical ***** optical fiber type can be G.**2, G.**3, G.**5 , 8 service channel at most, **0M~*0G of each channel , 1U, *9 inches. Function Features 1, providing upgrade interface to meet the demand of expanding the capacity. 2, 1*1 backup system for heat redundancy of power supply. 3, It provides various rate and service interfaces that support the service as Ethernet.PDH, SDH, CATV and Professional network. 4, transmission distance can be *0km, *0km, *0km, **0km, **0km and above when point to point without relay. 5, When the transmission distance without relay is over *0km, trunk equipment can be used to re-amplify, re-shape and re-timing the transmission signal. 6, Flexible network management configuration and management method. wavelength range: Compliant with standard of ITU*1 G.**5 Access Service Type:PDH, ATM, STM**4/STM**6/STM*4/STM- 1, OC***2/OC**8/OC**2/OC*3 FE, GE, *0GE FICON/ESCON/FIBER Channel/CATV Transmission Mode at Optical Interface :Adopts 2R transmission mode, each channel supporting transparent transmission at a rate below 2.5 Gbit/s. Adopts 3R transmission mode, each channel supports the rate such as **5Mbit/s, **2Mbit/s, 1.*5Gbit/s, 2.5Gbit/s, and *0Gbit/s (Optional) Topological Structures:Point to point , point to multi-point, chain, ring, single fiber bidirectional Power Supply:**0V/AC, *0Hz, **8V/DC rested in, pls contact me at any time .
