Chelsio compatible SM100G-SR Description

EdgeOptic's SM100G-SR compatible is a Chelsio-coded 100GBASE-SR4 version of the EdgeOptic 100G-QSFP28-100 multi-vendor short-reach transceiver, one universal QSFP28 module coded for multiple switch, router and adapter vendors. It carries 100G Ethernet over four parallel 850 nm VCSEL lanes at 25.78 Gbps each across multimode fiber, terminated on an MTP/MPO-12 (UPC) connector using 8 active fibers, 4 transmit and 4 receive. Reach is 70 m over OM3 and 100 m over OM4, per IEEE 802.3bm Clause 95. The transceiver port is female with no pins; the patch cable is the pinned male side, so a transceiver-to-transceiver link needs a male-to-male Type B MTP/MPO-12 cable.

Optical specifications include a 1.9 dB average link budget, receiver sensitivity of −10.3 dBm per lane, NRZ modulation, and no FEC required at this reach. The transmitter uses 850 nm VCSEL lasers; the receiver is a PIN photodiode. OM4 supports the full 100 m while OM3 is rated to 70 m, with achievable distance set by patch panels, splices, and connector cleanliness across the installed link. DDM/DOM reports transmit power, receive power and bias current per lane, plus module-level temperature and supply voltage, all per SFF-8636. The module runs across the 0 to 70 degrees C commercial range at 3.5 W maximum and is compliant with the QSFP28 MSA and CAUI-4 host interface. This is a 100G Ethernet short-reach optic; it does not carry Fibre Channel, OTN, or SONET traffic.

EdgeOptic codes this compatible with Chelsio-recognized EEPROM so the host reads it as a supported optic. Chelsio sells the SM100G-SR for its 100-Gigabit Ethernet adapters; the QSFP28 form factor matches the Chelsio T6 100G Unified Wire Adapter family. Confirm the specific adapter model against the Chelsio hardware compatibility guide before deployment. Typical roles include server and storage uplinks, data center core interconnects, and high-throughput compute fabrics.

Backed by 15+ years of EdgeOptic compatibility engineering across vendor optical platforms. Ships next business day from EU stock with a lifetime warranty. For project pricing or technical consultation, contact our sales team.

Frequently Asked Questions

Which Chelsio adapters take the SM100G-SR?

SM100G-SR is a QSFP28 module, so it fits Chelsio adapters with QSFP28 ports, which is the T6 100G generation rather than the QSFP+ based T5 line. Before ordering, verify the exact adapter model and supported optics against the Chelsio hardware compatibility guide at chelsio.com, since port form factor and firmware vary across the adapter range.
