Q2B85M70C00D is a high performance QSFP28 transceiver module for 100 Gigabit Ethernet data links over a multi-mode fibre pair. The maximum reach is 100m (OM4) or 70m (OM3). Four 25Gbps data streams are internally encoded into two 25GBd PAM4 signals, which are transmitted optically in two 850/900nm bidirectional links. At the receive side, the two 25GBd PAM4 signals are decoded and the four original 25Gbps data streams are recovered.
The two transmitters are 850 and 900nm Vertical Cavity Surface Emitting Lasers (VCSEL), each generating a 25GBd optical output signal. The two receivers are PIN photodiodes, each detecting a 25GBd optical input signal.
This transceiver module is compliant with the QSFP28 Multisource Agreement (MSA) and hot pluggable. Always contact Skylane Optics® commercial agents for compatibility with different equipment platforms.
