Broadcom AFCT-725SMZ Compatible 25GBASE-LR SFP28, 1310nm 10km

EdgeOptic's AFCT-725SMZ compatible is a Broadcom-coded version of the EdgeOptic 25G-SFP28-10 multi-vendor 25GBASE-LR transceiver. The same universal optical engine ships across multiple vendor codes, with the EEPROM programmed so Broadcom host equipment identifies it as a native AFCT-725SMZ. The module delivers 25 Gigabit Ethernet over duplex single-mode fiber at a 1310 nm nominal wavelength, reaching 10 km in line with IEEE 802.3cc and the SFP28 MSA.

The AFCT-725SMZ is the single-mode, long-reach member of the Broadcom 25G family, built for 1310 nm operation over single-mode fiber. It is a distinct part from the AFBR-725SMZ, which is a multimode 25GBASE-SR module at 850 nm over short reach. When sourcing a replacement, check the prefix carefully; AFCT and AFBR are not interchangeable because they use different wavelengths and fiber types.

Optically the transceiver pairs a DML laser transmitter with a PIN photodiode receiver. Launch power runs from a minimum of −7 dBm to a maximum of +2 dBm, receiver sensitivity is rated at −12 dBm, and the overload point is +3 dBm, giving a 5 dB optical path loss budget over the 10 km single-mode span. The module uses a duplex LC interface, operates across the standard commercial case temperature range of 0 to 70 °C, and draws up to 1.2 W. Digital diagnostics per SFF-8472 let the host read live temperature, supply voltage, laser bias, and optical power.

The EdgeOptic 25G-SFP28-10 platform behind this compatible carries a dual-rate envelope, supporting 25G Ethernet at 25.78 Gbps and 10G Ethernet at 10.31 Gbps depending on host port configuration, with 25G as the primary application. The module does not run forward error correction itself; where the link requires RS-FEC, the host applies it. The part works in Broadcom switch and adapter platforms used for data center site interconnect, mobile backhaul, and service provider aggregation; verify port assignment against the host transceiver table before deployment.

Built to the SFP28 MSA, SFF-8431, SFF-8432, and SFF-8472 specifications and CE and RoHS certified, the AFCT-725SMZ compatible is backed by 15+ years of EdgeOptic compatibility engineering across vendor optical platforms. It ships next business day from EU stock with a lifetime warranty. For volume pricing or coding questions, contact our sales team.
