100G QSFP28 SR4 optical module

The Chelsio SM100G-SR is a hot-pluggable QSFP28 transceiver designed for 100 Gigabit Ethernet links over multi-mode fibre. It operates at the 100GBase-SR4 standard for short-reach data centre interconnects. The module is RoHS-6 compliant and built for lead-free deployment. It targets network engineers expanding high-speed optical infrastructure.

Suited for Chelsio Unified Wire adapters

This module is validated for Chelsio T6 series Unified Wire adapters including the T62100-CR, T62100-LP-CR, T62100-SO-CR and T61100-OCP. It serves operators who need native compatibility with those specific cards. Buyers using switches or NICs from other vendors should verify qualification before purchase. It is not for single-mode fibre runs or longer-reach 100G applications.

100GBase-SR4 multi-mode interface

The decisive specification is the 100GBase-SR4 interface over multi-mode fibre with a QSFP28 form factor. This defines the reach, fibre type and port density the module supports. Confirm your hardware accepts this exact optical standard and connector style. No other interface or fibre mode is supported by this part.

Questions about this item

What distance does the 100GBase-SR4 interface cover over multi-mode fiber?

The module supports 100GBase-SR4 over multi-mode fiber for short-reach data center links.

Which slot and adapter models accept this hot-pluggable QSFP28 module?

It fits a QSFP28 cage and is validated for Chelsio Unified Wire adapters T62100-CR, T62100-LP-CR, T62100-SO-CR and T61100-OCP.

How is the module installed and what step is often missed?

Insert the transceiver until it clicks, then connect the MPO multi-mode patch cable; forgetting to remove the dust caps before cabling is the common error.
