Stable 1.25Gb/s BiDi Connectivity for Compact Fiber Links
This 1.25Gb/s 3km LC BiDi Cisco GLC-BX-D compatible transceiver is designed to give buyers a practical way to extend an Ethernet link over single-mode fiber while keeping the hardware footprint small and efficient. Built as a BiDi SFP module, it uses a single LC connector and supports up to 3 km on 9/125 μm SMF, making it a strong fit for network switch deployments where port density, cabling simplicity, and dependable link performance matter. For teams sourcing from optical transceiver manufacturers or planning installations around an ethernet switch, this module helps support stable point-to-point optical connections with the compatibility and operating clarity needed in real network environments.

Key Technical Support for Network and Switch Deployments
The module combines an 1550nm FP laser transmitter with a 1310nm PIN photo-detector, delivers up to 1.25Gb/s data links, and includes digital diagnostics through the SFF-8472-compliant monitoring interface for easier status checking and operational oversight. It runs on a single +3.3V power supply, has a maximum power draw of 1W, and is RoHS compliant and lead free, which supports procurement requirements for modern infrastructure programs. With industrial, extended, and commercial temperature versions available from -40°C to 85°C, -5°C to 85°C, or 0°C to 70°C, the transceiver is suitable for varied deployment conditions across top network switch manufacturers, system integrators, and maintenance teams that need predictable optics in mixed environments. The source content also notes a 12dB link budget, reinforcing its role in 1000BASE-BX-D and 1000Base-LX Ethernet use cases.

Practical Fit for Operators, Integrators, and Infrastructure Rollouts
For industrial Ethernet switch manufacturers, plant engineers, resellers, and operators building or expanding fiber-connected systems, this transceiver is a practical choice where a compact optical interface and verified compatibility are important. It is well suited for use in network switch installations, access-layer links, campus backbones, and other deployments where a poe switch or standard switch needs an optical uplink to a remote device or cabinet. Buyers evaluating a sfp module for Cisco GLC-BX-D compatible systems can use this option to support standardized procurement, simplify spare-part planning, and maintain reliable fiber connectivity across distributed networks.



Key Advantages

Stable Link Performance for Long-Distance Fiber Runs
This sfp module supports up to 1.25Gb/s data links and reaches 3 km over 9/125 μm single-mode fiber, which makes it a practical choice for buyers who need dependable optical transport in an ethernet switch or network switch setup. The 1550 nm FP laser transmitter and 1310 nm PIN photo-detector are paired to maintain consistent signal behavior, helping reduce link issues in fixed installations where uptime and predictable performance matter.

Built for Maintenance Efficiency and Industrial Compatibility

With a hot-pluggable single LC connector, single +3.3V power supply, and SFF-8472 monitoring support, this transceiver is structured to simplify installation, checks, and replacement for procurement teams and field engineers working with industrial ethernet switch manufacturers, optical transceiver manufacturers, and top network switch manufacturers. The available industrial, extended, and commercial temperature options, along with RoHS compliance and lead-free construction, make it well-suited for deployments where stability, sourcing consistency, and long service life are important.



Use Scenarios

Factory and Plant Network Uplinks
In factory floors and plant control areas, operators often need a fiber connection between an ethernet switch and remote devices where electrical noise, distance, and maintenance access can create problems. This transceiver serves as the optical link in an ethernet switch or poe switch environment, and its 3 km single-mode reach plus industrial temperature versions make it a practical fit for panels, machine cells, and control cabinets that require stable connection paths.

Equipment Integration for Switch and Module Suppliers

For OEMs, resellers, and system integrators building or stocking network switch and transceiver solutions, this part fits scenarios where a standard bi-directional optical interface is needed for customer projects with fixed fiber layouts. The single LC design, SFF-8472 diagnostics, and Cisco GLC-BX-D compatibility help reduce integration effort when supplying hardware to sites that need a reliable 1000BASE-BX-D connection in compact switch environments.



FAQ

Q1. What network applications is this SFP module suitable for?
The module is suited for 1000BASE-BX-D links up to 3 km on 9/125 μm single-mode fiber. It uses a single LC interface and is practical for switch-to-switch or switch-to-device connections in network switch deployments where a compact sfp module is required.

Q2. Is it compatible with Cisco GLC-BX-D ports?
Yes, this transceiver is compatible with Cisco GLC-BX-D requirements and is designed for 1.25Gb/s data links. Our module also follows the SFF MSA format, which supports integration in environments managed by top network switch manufacturers and related OEM platforms.

Q3. What optical specifications should I verify before installation?
The transmitter operates at 1550 nm with an FP laser, and the receiver uses a 1310 nm PIN photo-detector. Before deployment, we recommend confirming the target port type, fiber type, and link budget so our transceiver matches the intended ethernet switch connection.

Q4. What power and monitoring features does the module provide?
It runs from a single +3.3V power supply and supports a monitoring interface compliant with SFF-8472. That makes it practical for operators who need status visibility during maintenance, and our design keeps maximum power consumption at 1W for controlled system integration.

Q5. Which operating temperatures and compliance details are available?
Standard, extended, and industrial temperature versions are available, with operating ranges from 0°C to 70°C, -5°C to 85°C, or -40°C to 85°C. The unit is RoHS compliant and lead free, which is relevant for procurement teams sourcing from optical transceiver manufacturers or industrial ethernet switch manufacturers.
