This product is a 200Gb/s Quad Small Form Factor Pluggable-double density (QSFP-DD) optical module designed for optical communication applications.
This product is a 200Gb/s Quad Small Form Factor Pluggable-double density (QSFP-DD) optical module designed for optical communication applications. The module converts 8 channels of 25Gb/s (NRZ) electrical input data to 4 channels of LAN-WDM optical signals, and multiplexes them into a single channel for 200Gb/s(PMA4) optical transmission. Reversely, on the receiver side, the module optically de-multiplexes a 200Gb/s(PMA4) optical input into 4 channels of WDM optical signals, and converts them to 8 channels of 25Gb/s (NRZ) electrical output data. The central wavelengths of the 4 LAN WDM channels are 1295.56, 1300.05, 1304.58 and 1309.14 nm as members of the LAN WDM wavelength grid defined in IEEE802.3ba. It contains a duplex LC connector for the optical interface and a 76-pin connector for the electrical interface. To minimize the optical dispersion in the long-haul system, single-mode fiber (SMF) has to be applied in this module. It can support up to 30km with 200G FEC and 40km with built-in PFEC. The product is designed with form factor, optical/electrical connection and digital diagnostic interface according to the QSFP-DD Multi-Source Agreement (MSA). It has been designed to meet the harshest external operating conditions including temperature, humidity and EMI interference.
Features
● QSFP-DD MSA compliant
● 4 LWDM lanes MUX/DEMUX design
● Up to 40km transmission on single mode fiber (SMF) with built-in PFEC
● Operating case temperature: 0 to 70oC
● Maximum power consumption 12W
● Duplex LC connector
● RoHS compliant
