LINK-PP LS-BL273325-20I is an industrial-grade, single-fiber BiDi optical transceiver that merges rapid data throughput with long-distance reach. Designed for harsh environments, this compact solution minimizes cabling infrastructure while maximizing operational efficiency. It serves as an all-in-one remedy for modern networks needing reliable, wide-temperature optical links.
The device incorporates a 2-wire interface for management specifications compliant with the SFF-8472 digital diagnostic monitoring interface for optical transceivers. This standard-based design allows seamless host interaction and painless system integration. It ensures universal compatibility across diverse networking ecosystems.
Delivering a major leap in bandwidth, this module supplies a rapid 25Gbps data rate to handle heavy traffic loads in rugged environments. It meets the strict latency and speed requirements of automated factories and outdoor nodes.
By pairing 1270nm transmitting and 1330nm receiving channels, the transceiver splits bi-directional traffic onto distinct optical paths. This setup eliminates cross-talk and ensures clean, simultaneous upstream and downstream data flow.
The module spans long-range geographical distances up to 20km over single-mode fiber without suffering signal degradation. It provides ample power margin to link remote edge locations back to the central office securely.
Utilizing a single simplex LC/UPC connector, it halves the amount of physical fiber optic patch cords needed for installation. The precision-polished connector interface also keeps signal reflection low and connection stability high.
Integrated Digital Optical Monitoring (DOM) tracks vitals like internal temperature, laser bias current, and receiver power on the fly. This enables operators to troubleshoot network health remotely before an actual outage occurs.
