100G QSFP28 ZR4 optical transceiver: long distance and small size
QSFP28 ZR4 is the best choice for 100G long-haul DCI(Data Center Interconnect). The transmission distance of 100G QSFP28 ZR4 optical module can reach 80 km by accessing single-mode fiber, with built-in 4-channel cooled EML laser and PIN detector, using 4-way 25G NRZ wavelength division multiplexing technology (LWDM4), the transmission rate can reach 100Gpbs, mainly used in 100G Ethernet, data center, telecom and other scenarios. In addition to the 100G QSFP28 ZR4 optical transceiver, the 100G ultra-long-haul transmission solution also includes the 100G DCO coherent optical module, which is available in both CFP and CFP2 package types, with the CFP2 DCO offering greater flexibility and supporting higher panel density compared to the CFP DCO. 100G QSFP28 ZR4 optical transceiver CFP/CFP2 coherent optical modules use coherent technology, but coherent technology is typically used for long-haul metro optical transmission and is not suitable for use in data centers. Coherent technology uses
