Eoptolink has developed a QSFP28 ZR4 80km transceiver with excellent transmission performance. 100GE QSFP28 ZR4 module support 80km based on SM fiber without any external EDFA or DCM, low power consumption and good optical budget, the solution is designed for metro and data centre interconnect scenarios, and the transceiver can be used in most legacy switches, routers and transmission equipment for p2p applications.
Part number EOLQ-161HG-80-L7 – The QSFP28 ZR4 integrates the receiver and transmit path on one module. On the Tx side, 4 LAN-WDM lasers are used 1296 nm,1300nm,1305nm and 1309nm, the optical signals are multiplexed to SM mode fiber. On the receiver side, four lanes of optical data streams are amplified by internal SOA, then the optical signal are de-multiplexed and recovered by PIN detectors.
Eoptolink’s newly developed plug and play QSFP28 ZR4 can solve the problem of connecting switches/routers between data centers or other distant locations, without deploying complicated coherent solutions or using external EDFA or DCM modules.
