OM3738SX101 is a parallel full-duplex 200GE Quad Small Form Factor Pluggable (QSFP56) optical module designed for short-range multi-lane data communication. The optical module uses a 4-level pulse amplitude modulation (PAM4) format. It offers four data lanes based on 850 nm VCSEL/PD array technology, and is capable of an aggregate data rate of 200GE over 100 m OM4 MMF or 70 m OM3 MMF.

It is compliant with the IEEE 802.3cd 200GBASE SR4, IEEE 802.3bs 200GAUI-4 standards. Digital diagnostics functions are available via the I2C interface, as specified by the CMIS4.0 management interfaces.
