Qlogic compatible SFP25-SR-SP Description

EdgeOptic's SFP25-SR-SP compatible is a QLogic-coded version of the EdgeOptic 25G-SFP28-100 multi-vendor 25GBASE-SR SFP28 transceiver, built for QLogic (now Marvell) FastLinQ 41000-series 25 Gigabit Ethernet adapters. The module matches the QLogic original SKU for short-reach 25G Ethernet over multimode fiber and carries EEPROM programmed to identify as QLogic across FastLinQ firmware inventory checks.

Optical specs: 850 nm VCSEL transmitter, PIN photodiode receiver, TX power −5 to +2.4 dBm, RX sensitivity better than −10.3 dBm, 5.3 dB link budget. Reach is 100 m on OM4, 100 m on OM5, and 70 m on OM3 with an LC/UPC duplex connector. The module is IEEE 802.3by Clause 112 compliant. RS-FEC per Clause 91 (RS(528,514)) is supported and enabled by the host port when 25GBASE-SR is negotiated.

Electrical interface follows SFF-8431 and SFF-8432 for the SFP28 cage. The module is optically qualified for 25GBASE-SR per IEEE 802.3by Clause 112; operation at 10G rates on dual-rate FastLinQ ports is a host SerDes function, not an optical performance guarantee by this module. For pure 10G deployments, use a dedicated 10GBASE-SR SFP+. DOM telemetry is SFF-8472 compliant for per-module temperature, supply voltage, TX bias, TX power, and RX power readable through FastLinQ driver tools and standard SNMP. Power dissipation is 0.3 W and the module operates across 0 to 70 C.

The primary deployment is the QLogic FastLinQ 41000-series 25G Ethernet adapter family, including the QL41112H, QL41162H, QL41262, and QL41234. Marvell completed its acquisition of Cavium (which then held QLogic networking assets) in 2018, and the FastLinQ adapter line continues under Marvell ownership. EdgeOptic's SFP25-SR-SP is programmed with QLogic-recognized identification so the module is accepted at link-up without driver-level workarounds or forced third-party flags. For Marvell-rebadged FastLinQ 25G adapters, verify per-model coding against the Marvell FastLinQ 41000 Series product documentation.

For FastLinQ deployments needing alternate EEPROM coding, or for FastLinQ-coded optics in mixed-vendor hardware, verify against the host vendor's transceiver compatibility matrix before ordering and contact our sales team for platform-specific coding options. Ships next business day from EU stock with a lifetime warranty. Backed by 15+ years of EdgeOptic compatibility engineering across vendor optical platforms.

Frequently Asked Questions

Which QLogic and Marvell FastLinQ adapters support the SFP25-SR-SP transceiver?

The primary deployment is the QLogic FastLinQ 41000-series 25G Ethernet adapter family, including the QL41112H, QL41162H, QL41262, and QL41234. Marvell's rebadged FastLinQ 25G adapters use the same firmware family and are generally expected to accept SFP25-SR-SP coded optics; for per-model adapter qualification, consult the Marvell FastLinQ 41000 Series product documentation.

Does the SFP25-SR-SP run at 10G as well as 25G?

The SFP28 electrical interface spans 8.5 to 28.1 Gbps, so the host SerDes can clock this module at 10G on dual-rate FastLinQ ports for backward compatibility. Optically the module is qualified for 25GBASE-SR only per IEEE 802.3by Clause 112; 10G-rate operation is host-governed and is not a validated optical equivalent to a dedicated 10GBASE-SR module. For pure 10G deployments, use a dedicated 10GBASE-SR SFP+.
