Huawei SFP-25G-LR (02312LSE) Compatible 25GBASE-LR SFP28 10 km

EdgeOptic's SFP-25G-LR compatible is a Huawei-coded dual-rate 10G/25G LR SFP28 transceiver and the Huawei-coded variant of the EdgeOptic 25G-SFP28-10 multi-vendor 25GBASE-LR catalog. Huawei catalogs this optic as SFP-25G-LR, with the optical module ordering code 02312LSE referenced in Huawei procurement systems. The module carries 10 Gigabit Ethernet (10.31 Gbps) and 25 Gigabit Ethernet (25.78 Gbps) over a single G.652 SMF pair at 1310 nm, terminated with a duplex LC/UPC connector.

The transmitter is a DML driving the 1310 nm LC duplex; the receiver is a PIN photodiode. Optical specifications: TX output power −7 to +2 dBm, RX sensitivity −12 dBm, RX overload +3 dBm, minimum extinction ratio 3.5 dB, and a 5 dB optical link budget over the 10 km specified reach on G.652 SMF. Real reach on a long link is loss-limited by installed fiber attenuation, splice loss, and connector loss, so on spans above 8 km calculate end-to-end insertion loss against the 5 dB budget rather than the nominal 10 km figure. The module operates 0 to 70 °C on a +3.3 V single supply with 1.2 W maximum power consumption.

At 25G operation the host MAC performs RS(528,514) RS-FEC; the module itself has no built-in FEC. Huawei CloudEngine VRP configures FEC per port and per platform, and behavior varies across VRP software releases. The FEC mode must agree on both link partners or the link comes up down without optical errors, so verify the per-interface FEC configuration on both ends before commissioning. At 10G operation the optic behaves as a standard 10GBASE-LR module and host-side FEC is not required, but the host port must support dual-rate selection between 10G and 25G on its SFP28 cage. DDM diagnostics report TX power, RX power, module temperature, laser bias, and supply voltage in real time per SFF-8472 and are accessible through the VRP management interface.

The module ships with Huawei-recognized EEPROM coding for clean registration under Huawei VRP. The Huawei VRP behavior around third-party-transceiver override commands has changed across releases, so confirm the active VRP version against the Huawei product support documentation for the target CloudEngine platform before deployment. SFP-25G-LR targets Huawei CloudEngine 25G SFP28 ports across the CloudEngine switch family. Verify the specific CloudEngine chassis, line card, and VRP release against the Huawei product support documentation or Huawei optical module compatibility list before ordering, because per-platform coverage changes between VRP versions and the applicable Huawei ordering code may differ between switch families and routing-platform families. Conforms to IEEE 802.3cc, SFF-8431, SFF-8432, SFF-8472, and the SFP28 MSA.
