25GBASE-LR-S SFP28 1310nm 300m DDM Optical Transceiver Module

Cisco Compatible 25GBASE-LR-S SFP28 DOM Optical Transceiver Module for Data Centers provides dependable 25GbE connectivity over single-mode fiber (SMF) within a 300m reach at 1310nm. The SFP28 is provided with a duplex LC connector and supports real-time Digital Diagnostic Monitoring (DDM), which provides information on temperature, voltage, bias, Tx/Rx power, and more for proactive management. The transceiver is built to MSA SFP28 specifications and supports a wide range of line rates from 9.8304 to 25.78125 Gbps via an SFI electrical interface. The Cisco Compatible 25GBASE-LR-S SFP28 DOM Optical Transceiver Module is ideal for high-performance, high-speed data center applications. The transceiver features a 1310nm DFB laser transmitter and a PIN receiver, which are housed in a low EMI metal enclosure that provides stable operation in dense networking environments.

The module also operates from a single +3.3V power supply with average power consumption below 1.0W in normal operation, contributing to favorable power consumption. A 2-wire interface is integrated into the standard to allow for digital diagnostics. The module supports hot-pluggable operation while also being RoHS compliant and has an operating temperature range of 0 to 70°C. The module lends itself well to 25G uplinks, as well as TOR-to-spine connections, and short-range support (up to 300m) for SMF applications, plus additional multimode reach with OM4, OM3, and OM2 fibers. This Optical Transceiver Module ultimately ensures seamless integration and high-performance networking capabilities for your data center.
