Q100G-ER4L, QSFP28 Optical Transceiver Module, SMF, 1310nm, 30km (40km with FEC), LC, DOM

This QSFP28 optical transceiver module is designed for 100GBASE-ER4L Ethernet applications over single-mode fiber (SMF) with a maximum reach of up to 40km, using a 1310nm wavelength and duplex LC connectors. It transmits 100 Gigabit Ethernet via four multiplexed wavelengths, with internal multiplexing and demultiplexing handled by the module itself.

Engineered with a BOX+FPC+PCBA separation structure, the transceiver delivers excellent reliability, hermetic sealing, and efficient thermal performance. It complies with the IEEE 802.3ba standard and supports digital diagnostics monitoring (DDM) via the I2C interface, following the QSFP28 MSA specification, enabling real-time access to key operational parameters.

Hot-swappable and easy to deploy, this transceiver is ideal for 100G telecom links, data center interconnects, enterprise core/distribution layers, and high-performance computing networks.
