Product Introduction
25G SFP28 Transceiver Module
25GBASE SFP28 Optical Module Overview
Product Overview
The 25G SFP28 transceiver is a compact single-channel fiber optic solution compliant with IEEE 802.3by and SFF-8472 MSA standards, widely deployed for cloud data center ToR interconnection, 5G fronthaul CPRI Option 10, 32G Fibre Channel and 100G QSFP28 breakout links. This standard 25G SFP28 optical module adopts built-in dual CDR chips, supporting dual rate operation at 24.33Gbps / 25.78Gbps (CDR on) and 9.95Gbps / 10.31Gbps (CDR bypass), delivering flexible compatibility for mixed 10G/25G network environments.
Our complete lineup of industry-standard 25GBASE SFP28 fiber transceivers covers full transmission distances from 100m up to 40km, including multimode 25GBASE-SR, single-mode 25GBASE-LR, extended long-reach 25GBASE-ER, BiDi simplex LC bidirectional modules (10km / 30km) and CWDM wavelength division multiplex modules. Equipped with duplex LC and simplex LC standard interfaces, these 25G SFP28 fiber modules support MMF multimode fiber and SMF single-mode fiber, realizing plug-and-play interoperability with mainstream switches, servers, BBU and AAU telecom equipment.
All 25G SFP28 transceivers feature single 3.3V low-power design, electrically hot-pluggable SFP28 form factor and built-in digital diagnostic monitoring. Available in commercial temperature (0°C ~ 70°C) and industrial wide-temperature options, the full portfolio meets short-range rack links, medium campus interconnection and long-distance metro 5G fronthaul transmission demands.
