200GBASE-SR4 QSFP56
LIQM-NKSxxxC
Max Reach: 100 meters
The 200G QSFP56 Optical Transceiver is designed for 200 Gigabit Ethernet links over OM3, OM4, and OM5 multimode fiber, with optimized performance in liquid immersion cooling environments.
The module complies with the QSFP56 MSA, IEEE 802.3cd 200GBASE-SR4, and CMIS Rev. 4.0 specifications. Digital diagnostic monitoring (DDM) functions are available through the I²C management interface as defined by CMIS.
The transceiver integrates four transmit and four receive lanes, each operating at 53.125 Gb/s, providing an aggregate data rate of 200 Gb/s.
The optical interface utilizes a male MPO-12 optical pigtail. The internal optical assembly is sealed using a specialized protection technology designed to prevent dielectric cooling fluid ingress, ensuring reliable operation in liquid immersion cooling applications.
