◆ Description:

Miray’s GE-BX20-SM1310 Transceivers are a high performance, cost effective module which have a single LC optics interface. They are compatible with the Small Form Factor Pluggable Multi-Sourcing Agreement (MSA) and Digital diagnostics functions are available via the 2-wire serial bus specified in SFF-8472. The receiver section uses a PIN receiver and the transmitter uses a 1310 nm FP laser, up to 14dB link budge ensure this module 1000Base-LX Ethernet 20km application.

Reliable 1.25Gb/s BiDi SFP for Practical Network Expansion
This 1.25Gb/s LC BiDi SFP module is built for buyers who need a dependable optical link for network switch deployments, especially when port density, cabling simplicity, and link stability matter. With a single LC connector and bidirectional operation, it helps reduce fiber count while supporting fast data links up to 1.25Gb/s, making it a practical fit for ethernet switch installations, access-layer upgrades, and long-reach connections where a compact sfp module is preferred. For system teams working with top network switch manufacturers or sourcing from optical transceiver manufacturers, this module offers a straightforward way to extend fiber connectivity without adding unnecessary complexity.

Technical Features That Support Stable 20km Fiber Links
Built around a 1310nm FP laser transmitter and 1550nm PIN photo-detector, this transceiver is designed for up to 20km transmission over 9/125 μm single-mode fiber, with a reported link budget suited to 1000Base-LX Ethernet use cases. It is hot-pluggable, runs on a single +3.3V power supply, and includes monitoring functions through the SFF-8472 compliant 2-wire serial interface, giving operators the visibility needed for maintenance and diagnostics. With a maximum power draw of 1W and RoHS-compliant, lead-free construction, it aligns with procurement needs for controlled, lower-power optical components used in industrial ethernet switch manufacturers, poe switch platforms, and standard transceiver inventories.

Application Fit for Industrial, Commercial, and Extended Temperature Environments
This module is well suited to real-world deployments where a reliable optical interface is required across different operating conditions, including industrial, extended, and commercial temperature ranges from -40°C to 85°C, -5°C to 85°C, or 0°C to 70°C depending on version. That makes it a practical choice for plant networks, edge systems, warehouse infrastructure, and field cabinets where teams need a stable network switch connection between sites or across buildings. Whether used by resellers supporting customer rollouts, integrators building fiber uplinks, or operators maintaining an ethernet switch network, this sfp module offers a dependable option for 1.25Gb/s optical transport with a clear fit for long-distance, single-fiber applications.

Key Advantages

Reliable 1.25Gb/s BiDi Performance
This sfp module supports up to 1.25Gb/s data links with a 1310nm FP transmitter and 1550nm PIN receiver, giving network teams a practical way to extend ethernet switch connections over 20km of 9/125 μm single-mode fiber. The single LC interface reduces fiber count and simplifies port planning, which is valuable for industrial ethernet switch manufacturers, optical transceiver manufacturers, and procurement teams that need stable optics for long-reach deployments in a network switch or poe switch environment.

Industrial-Grade Integration and Maintenance
With hot-pluggable operation, single +3.3V power supply, SFF-8472 monitoring, and RoHS-compliant lead-free construction, this transceiver is designed for practical installation and service work. The ability to read digital diagnostics helps operators identify link conditions early, which supports faster troubleshooting and less downtime in systems supplied by top network switch manufacturers and deployed in standard, extended, or industrial temperature ranges.

Use Scenarios

Factory Network Uplinks
In factory halls and control rooms, operators often need a stable optical link between an ethernet switch on the production floor and another switch in a distant cabinet or equipment room. This transceiver serves that role by carrying 1.25Gb/s traffic over single-mode fiber up to 20km, which makes it well-suited for long uplinks in automation lines, monitoring networks, and plant backbones where fiber count and cable distance must be managed carefully.

Outdoor Cabinets and Remote Facilities
In remote utility sites, roadside cabinets, and building-to-building links, teams need optics that can tolerate demanding operating conditions and still support predictable transmission. This module fits those deployments by combining BiDi fiber use, hot-pluggable handling, and industrial temperature options, so it can function as the optical interface in a network switch or poe switch installation where maintenance access is limited and reliability matters.

FAQ

Q1. What networks is this SFP module designed for?
This module is built for 1.25Gb/s data links and supports 1000Base-LX Ethernet applications over up to 20 km of 9/125 μm single-mode fiber. It uses a single LC interface, so our sfp module is well-suited for network switch deployments that require stable long-distance optical connectivity.

Q2. Is this transceiver compatible with Cisco equipment?
Yes, this is a Cisco compatible transceiver module. Our design follows the SFF MSA format and includes digital diagnostics via the SFF-8472 2-wire serial bus, which helps system integrators verify module status during deployment. It is intended for use in compatible switch and optical networking environments.

Q3. What are the optical specifications of this module?
The transmitter operates at 1310 nm with an FP laser, and the receiver uses a 1550 nm PIN photodetector. This BiDi configuration uses a single LC connector to transmit and receive on different wavelengths, and our module provides up to 14 dB link budget for the stated 20 km reach.

Q4. Can it be used in industrial or temperature-sensitive installations?
Standard units are available in multiple operating temperature versions: industrial, extended, and commercial. Depending on the version, the range is -40°C to 85°C, -5°C to 85°C, or 0°C to 70°C. This gives plant engineers and industrial ethernet switch manufacturers practical options for different site conditions.

Q5. What power and compliance features should procurement teams note?
The module runs from a single +3.3V power supply and has a maximum power consumption of 1W. It is RoHS compliant and lead free, which supports standard procurement requirements for optical networking parts. We provide a practical fit for teams sourcing optical transceiver manufacturers and switch platforms.
