Cisco compatible QSFP-100G-SM-SR Description
EdgeOptic's QSFP-100G-SM-SR compatible is a Cisco-coded 100GBASE-CWDM4 Lite version of the EdgeOptic 100G-QSFP28-2.1 multi-vendor CWDM4 QSFP28 2km transceiver. The Cisco spare ordering variant QSFP-100G-SM-SR= refers to the same module.
The module uses the four-channel CWDM grid at 1271, 1291, 1311, and 1331 nm with NRZ modulation across each lane. Output is duplex LC/UPC and the module supports 2 km links over G.652 single-mode fibre. The optical front end uses DML transmitters and PIN receivers. Host-side FEC is required as defined by the CLR4 Alliance specification.
The QSFP-100G-SM-SR covers 100 Gigabit Ethernet at 103.125 Gbps per Cisco's specifications. The EdgeOptic 100G-QSFP28-2.1 platform additionally supports OTU4 (112 Gbps) and 4x32G Fibre Channel (112.2 Gbps) variants for transport and SAN deployments. Those rates ship as separate part numbers, so for OTU4 or Fibre Channel coding contact our sales team.
QSFP-100G-SM-SR is Cisco's CLR4 variant of CWDM4. It is interoperable with QSFP-100G-CWDM4-S on the same link, since both implementations use the same CWDM wavelength plan. The SM-SR specification carries a tighter optical budget allocation than full CWDM4 MSA, so engineers planning links should check that the loss budget matches the deployed fibre plant before mixing the two part numbers across endpoints.
Works on Cisco Nexus 9000 and Catalyst 9500 platforms supporting QSFP28 100G CWDM4 optics, with Nexus 9000 line-card CWDM4 support documented from NX-OS 9.2(2) onwards. For exhaustive per-chassis and per-line-card compatibility, verify against the Cisco Transceiver Module Group compatibility matrix. EdgeOptic codes our Cisco compatibles with Cisco-recognized EEPROM, so the module initializes on Nexus and Catalyst without the service unsupported-transceiver command.
The QSFP-100G-SM-SR specification narrows the operating temperature relative to the broader CWDM4-S commercial range. For deployments in unheated or cold-environment data halls, confirm the operating temperature window against Cisco's published specification for QSFP-100G-SM-SR rather than assuming the wider CWDM4-S range.
Digital diagnostics (DDM/DOM) report TX power, RX power, bias current, supply voltage, and temperature per SFF-8636. The module is QSFP28 MSA SFF-8665 compliant and aligned with the 100G CLR4 Alliance specification.
Backed by 15+ years of EdgeOptic compatibility engineering across vendor optical platforms. Ships next business day from EU stock with a lifetime warranty.
Frequently Asked Questions
What is the difference between QSFP-100G-SM-SR and QSFP-100G-CWDM4-S?
QSFP-100G-SM-SR implements the CLR4 Alliance specification, sometimes called CWDM4 Lite, with a tighter optical loss budget than full CWDM4 MSA. QSFP-100G-CWDM4-S is the full CWDM4 MSA implementation with a wider loss budget and a broader commercial operating temperature range. Both use the same four-channel CWDM wavelength plan at 1271, 1291, 1311, and 1331 nm and are interoperable on a single link per Cisco. The two part numbers are not always swappable in cold environments or on tight-budget fibre plants, so verify the deployed temperature and loss budget against Cisco's published specifications before mixing them.
Does QSFP-100G-SM-SR need the service unsupported-transceiver command on Cisco Nexus?
No. EdgeOptic codes our Cisco-compatible QSFP-100G-SM-SR with Cisco-recognized EEPROM, so Nexus and Catalyst platforms accept the module on initialization without requiring the service unsupported-transceiver workaround. That CLI is needed for generic third-party optics whose vendor codes Cisco does not recognize; it is not needed for EdgeOptic's Cisco-coded compatible.
What is the QSFP-100G-SM-SR= spare ordering code?
The trailing equals sign is Cisco's standard spare ordering convention. QSFP-100G-SM-SR and QSFP-100G-SM-SR= refer to the same module. The equals-suffix code is used when the part is ordered as a field-replaceable spare separate from a system configuration.
Does QSFP-100G-SM-SR support OTU4 or 4x32G Fibre Channel?
The QSFP-100G-SM-SR is a 100GE-only module per Cisco's specifications. The EdgeOptic 100G-QSFP28-2.1 platform additionally supports OTU4 (112 Gbps) and 4x32G Fibre Channel (112.2 Gbps) as separate variants. For OTU4 or Fibre Channel ordering, contact our sales team.
