Chelsio compatible SM100G-LR Description
EdgeOptic's SM100G-LR compatible is a Chelsio-coded 100GBASE-LR4 QSFP28 transceiver built on the EdgeOptic 100G-QSFP28-10 platform. Chelsio's SM100G-LR is the long-reach companion to the SM100G-SR module and is positioned for 10 km links on Chelsio's T6-series 100G Unified Wire adapters. The EdgeOptic compatible carries Chelsio-recognized EEPROM identifiers so the host adapter and operating-system telemetry surface the expected SM100G-LR ordering code, and it ships with the same wavelength plan, electrical interface, and SFF-8636 management profile as the OEM module.
The optical interface follows IEEE 802.3ba Clause 88 100GBASE-LR4. Four 25.78 Gbps NRZ lanes ride the LAN WDM grid at 1295.56, 1300.05, 1304.58, and 1309.14 nm, then multiplex onto a single LC duplex pair of single-mode fiber. The 6.3 dB optical path loss budget supports a full 10 km reach on G.652 SMF. Host electrical interface is CAUI-4 (4x25G NRZ) into the QSFP28 cage. Power consumption peaks at 3.5 W, and the module reports DDM telemetry per SFF-8636 for tx power, rx power, bias current, supply voltage, and case temperature. Operating temperature is 0 to 70 C commercial range. The EdgeOptic compatible carries CE marking and RoHS compliance.
Chelsio's primary use case for SM100G-LR is the T6-series 100G adapter family. These adapters ship without bundled optics, and Chelsio lists SM100G-SR for short reach and SM100G-LR for the 10 km LR4 link option. EdgeOptic's compatible covers the LR4 use case with matching Chelsio EEPROM coding so the adapter driver enumerates the module as expected. The compatible also operates in third-party QSFP28 hosts that accept LR4 ordering codes, since the optical and electrical interfaces follow IEEE 802.3ba and the QSFP28 MSA. The commercial-temperature variant covered here is distinct from Chelsio's SM100G-LR-I industrial variant, which carries a wider temperature window.
Compatible with Chelsio T6-series 100G adapters and third-party QSFP28 hosts that accept LR4 ordering codes; verify the entry for your specific adapter model in Chelsio's compatibility documentation before deployment. Ships next business day from EU stock with a lifetime warranty. Backed by 15+ years of EdgeOptic compatibility engineering across vendor optical platforms.
