400G QSFP112 SR4 100m Optical Transceiver – APX-QSFP112-400G-100m-SR4
Product Overview
The Apex APX-QSFP112-400G-100m-SR4 is a 400G QSFP112 SR4 optical transceiver engineered for high-density data center and telecom networks. It transmits up to 100m over OM4 multi-mode fiber (MMF), delivering dependable 400G connectivity for modern AI and cloud infrastructure.
Built in a QSFP112 form factor with an MPO-12 optical interface, the APX-QSFP112-400G-100m-SR4 aggregates 4 x 100G PAM4 electrical lanes into a single hot-pluggable module. Four 850nm VCSEL based PAM4 lanes are carried over OM4 multi-mode fiber through an MPO-12 interface. It is compatible with major networking platforms and supports plug-and-play deployment in existing racks.
Engineered for 400G switching and transport fabrics, this transceiver delivers consistent optical performance with low power consumption and full digital diagnostics for scalable, serviceable network infrastructure.
