SFP28 25G SMF BiDi Optical Transceiver for Long-Range Single-Mode Fiber Networks - Compatible with Cisco and MSA

The 25G SFP28 BiDi Optical Transceiver Module from Intellinet Network Solutions is designed to deliver reliable high-speed connectivity for modern enterprise, campus, telecom, datacenter, and cloud network environments. Supporting the IEEE 802.3by 25GBASE-LR Ethernet standard, it enables data transfer rates up to 25 Gbps over single-mode fiber connections with transmission distances of up to 10 km (6.2 mi.). Its compact SFP28 form factor makes it ideal for high-density network infrastructures requiring scalable and efficient 25G connectivity.

Optimized for Long-Distance 25G Ethernet Connectivity

Featuring one LC simplex single-mode fiber port, the transceiver supports bi-directional (BiDi) communication over a single fiber strand using complementary transmit and receive wavelengths of 1270 nm and 1330 nm. This advanced BiDi design helps maximize existing fiber infrastructure while supporting high-bandwidth data transmission for backbone, aggregation, and core network applications across campuses, datacenters, and telecom environments.

Broad Compatibility with Leading Network Platforms

The module is MSA-compliant to ensure seamless interoperability with a wide range of switches, routers, and networking equipment from leading manufacturers including Cisco, Intellinet Network Solutions, ZyXEL, TP-Link, Ubiquiti, and more. Equivalent to the Cisco SFP-25G-BXU-I transceiver model, it provides a reliable and cost-effective solution for expanding or upgrading existing 25G network deployments while maintaining compatibility with established hardware ecosystems.

Advanced Monitoring and Reliable Operation with DDM / DOM

Integrated digital diagnostics monitoring (DDM) and digital optical monitoring (DOM) functions provide real-time access to critical operating parameters such as temperature, voltage, and optical signal levels. This allows administrators to monitor transceiver performance and simplify network maintenance and troubleshooting in demanding enterprise and datacenter environments.

Durable Design for Enterprise and Datacenter Environments

A fully metallic housing minimizes electromagnetic interference (EMI) and enhances durability for stable operation in high-performance networking applications. Hot-plug support allows the transceiver to be installed or replaced without shutting down connected equipment, reducing maintenance downtime and improving service continuity in mission-critical network infrastructures.
