Bidirectional Gigabit SFP optical module for 20km single-mode fiber transmission at 1.25Gb/s.
Extending network reach in industrial or campus environments often requires cost-effective long-distance connectivity without deploying dual fibers. The LRGP1315-20ATLB addresses this by enabling bidirectional transmission over a single strand of single-mode fiber, simplifying cabling infrastructure.
This module delivers 1.25Gb/s bi-directional data transmission using a 1310nm FP laser transmitter, achieving a reliable range of 20km on 9/125um fiber. With Class C operating temperature support (-40℃~70℃) and hot-swappable design, it ensures stable performance in demanding conditions while reducing deployment complexity.
Ideal for Gigabit Ethernet and 1.063Gb/s Fiber Channel applications, the LRGP1315-20ATLB provides a robust solution for extending network links where fiber conservation is critical. Its compliance with SFF-8472 and RoHS standards guarantees interoperability and environmental safety for enterprise deployments.
Enables data transmission over a single fiber strand, saving fiber resources.
Supports transmission distances up to 20km on single-mode fiber.
Industrial grade Class C operation from -40℃ to 70℃ for harsh environments.
Allows installation and removal without powering down the system.
Implements DDM via 2-wire serial bus for real-time monitoring.
Complete technical details for integration and deployment planning.
