The 32Gbps SFP28 SR Transceiver is a high-performance optical module designed for short-range communication over multimode fiber (MMF) with transmission distances of up to 70 meters on OM3 fiber and 100 meters on OM4 fiber. Featuring an 850nm VCSEL laser and a PIN photodiode, this transceiver supports data rates up to 28.05Gbps, making it suitable for 16G and 32G Fibre Channel applications. Compliant with SFP28 MSA and SFF-8472 standards, it offers hot-pluggable functionality and a duplex LC interface for seamless integration with modern networking systems.
Operating on a +3.3V power supply, the module is energy-efficient, consuming a maximum current of 300mA. It is available in two temperature grades: standard (0°C to 70°C) for commercial use and industrial (-40°C to 85°C) for harsh environments. The transmitter provides an average optical output power ranging from -8.4dBm to +2.4dBm, with an extinction ratio of 2.0dB, while the receiver offers a sensitivity of -10dBm and an overload threshold of +2.4dBm. Advanced diagnostics, including Loss of Signal (LOS) detection and real-time digital monitoring, ensure reliable operation and facilitate proactive maintenance.
This hot-pluggable transceiver supports up to 28.05 Gbps line rate for 32G Fibre Channel and is backward compatible with 16GFC. It operates over OM3 MMF up to 70 m and OM4 MMF up to 100 m using a duplex LC connector. The module integrates a VCSEL transmitter, PIN/TIA receiver, and MCU controller, with power consumption <1 W on a single 3.3 V supply. Available in commercial (0 °C to +70 °C) and industrial (−40 °C to +85 °C) grades, it supports DDMI for real-time optical monitoring.
