Extreme Networks AFCT-725SMZ-EX Optical Transceiver Module

Technical SpecificationsModel：AFCT-725SMZ-EX Brand：Extreme Networks Product Type：Hot-swappable SFP28 optical transceiver

Interface: SFP28, SFF-8472 MSA compliant Standard: IEEE 802.3cd 25GBASE-LR Data Rate: 25.78Gbps NRZ Wavelength: 1310nm DFB laser Fiber: G.652 single-mode fiber (SMF) Max Reach: 10km Connector: Duplex LC/UPC Monitoring: DOM digital optical monitoring (temperature, supply voltage, Tx/Rx optical power) Power consumption: Max 1.2W Hot swap: Yes Laser Class: Class 1 Operating temperature：0℃ ~ +70℃

System compatibility

AFCT-725SMZ-EX is Extreme Networks original SFP28 transceiver. Works on Extreme switches/routers with SFP28 ports, including SLX9850, X870 series. EEPROM pre-flashed for Extreme firmware recognition. It works for 25G leaf server access and can be used in breakout ports from QSFP28 interfaces.

Function

AFCT-725SMZ-EX is 25GBASE-LR SFP28 long-reach transceiver. It transmits 25G NRZ signal over single-mode fiber up to 10km. Low power consumption reduces thermal load on high-density data center switches. DOM function enables real-time optical link monitoring, widely used in leaf-spine architecture, HPC and enterprise core network.

Installation

Insert SFP28 module into SFP28 port until latch locks. Connect duplex LC single-mode fiber patch cord. Verify module detection and optical power via SLX-OS / ExtremeXOS CLI. Keep fiber end faces clean and check fiber polarity.
