LINK-PP LS-BL273325-10I is an industrial-grade 25G SFP28 BiDi optical transceiver module designed for robust single-fiber bidirectional data transmission. It integrates advanced 1270nm-TX/1330nm-RX wavelength architecture and real-time DOM monitoring to ensure optimal network stability. This module offers an ideal combination of extended reach, power efficiency, and hardened thermal endurance.
This module features a transmit power of -3 to +5dBm and supports a wide receiver power range from -14 to +3dBm. These optimized optical power specifications ensure an excellent power budget for stable data links. By maintaining these strict optical levels, the transceiver prevents signal distortion and ensures reliable network communication.
Delivering a rapid 25Gbps data rate, this module satisfies the increasing bandwidth demands of crowded edge networks. It significantly accelerates data throughput to reduce latency in localized processing hubs. This makes it an ideal solution for dense infrastructure requiring swift and efficient traffic handling.
The transceiver utilizes a specialized 1270nm transmit and 1330nm receive wavelength configuration. This BiDi (bidirectional) design allows simultaneous upstream and downstream traffic over one single strand of fiber. As a result, it effectively maximizes existing fiber capacity without the need for deploying extra cables.
Engineered for long-reach applications, this optical module supports data transmission distances up to 10km over 9/125µm single-mode fiber (SMF). It maintains reliable connectivity and low bit error rates across the entire span. This makes it highly suitable for connecting geographically dispersed nodes or regional stations.
Featuring a single-port Simplex LC/UPC connector, the module ensures easy deployment and a secure physical connection. This compact interface design reduces cabling clutter and optimizes patch panel space. It allows operators to streamline physical fiber management while saving deployment costs.
Equipped with Digital Optical Monitoring (DOM) capabilities, the module allows network administrators to track vital parameters instantly. Users can monitor real-time metrics such as temperature, supply voltage, laser bias current, and optical power. This proactive diagnostics feature helps detect potential anomalies and prevents unexpected network downtime.
