◆ Description:

Miray’s GE-BX40-SM1550 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 1550 nm DFB laser, up to 21dB link budge ensure this module 1000Base-EX Ethernet 40km application.

High-Value BiDi Fiber Extension for Long-Reach Ethernet Links
This Cisco compatible GLC-BX40-D sfp module is built to extend Ethernet connections with a practical 1.25Gb/s data rate, making it a reliable choice for teams that need stable long-distance fiber transport without adding complexity. With 1000BASE-BX-D BiDi operation, a single LC connector, and up to 40km reach over 9/125μm SMF, it helps reduce fiber count while supporting clear point-to-point link deployment in access, campus, and industrial network layouts. For buyers sourcing from optical transceiver manufacturers or comparing modules for deployment inside an ethernet switch infrastructure, this unit offers a balanced mix of performance, compatibility, and operational practicality.

Verified Optical Performance and Monitoring for Network Operations
The module uses a 1550nm DFB laser transmitter and 1310nm PIN photo-detector, with DOM support through the SFF-8472-compliant monitoring interface, so operations teams can track link status and optical conditions with more confidence. Its hot-pluggable design supports straightforward installation and replacement in live systems, while the single +3.3V power supply and maximum 1W power profile keep integration requirements manageable. These characteristics are especially useful for industrial ethernet switch manufacturers, top network switch manufacturers, and maintenance teams that need consistent transceiver behavior across switches, including poe switch and standard network switch platforms where dependable optics matter for uptime and service continuity.

Practical Fit for Industrial and Commercial Network Deployments
Available in industrial, extended, and commercial temperature versions, this transceiver is well suited to deployments ranging from -40°C to 85°C, -5°C to 85°C, or 0°C to 70°C depending on the selected model, with RoHS compliance and lead-free construction supporting modern procurement standards. That makes it a practical option for plant rooms, outdoor cabinets, telecom closets, and other controlled or harsh environments where an ethernet switch or network switch must connect reliably over long fiber runs. For distributors, resellers, and operators supporting mixed vendor environments, this Cisco compatible transceiver provides a dependable replacement or expansion choice for systems built around standard SFP interfaces.

Key Advantages

Reliable compatibility for network infrastructure
This sfp module is built to work with standard 1000BASE-BX-D links and supports a single LC interface, which makes it practical for OEMs, procurement teams, and system integrators sourcing parts for an ethernet switch or related optical link. As a Cisco compatible transceiver, it helps reduce integration risk while keeping replacement and expansion planning straightforward for teams that need stable parts supply from optical transceiver manufacturers and top network switch manufacturers.

Stable performance with industrial operating options
With up to 1.25Gb/s data links, up to 40km reach on 9/125 μm SMF, DOM support, and SFF-8472 monitoring, this module is designed to support link visibility and predictable operation over time. The available industrial, extended, and commercial temperature ranges make it suitable for demanding sites where a network switch, poe switch, or optical uplink must keep operating under changing environmental conditions, while the low 1W maximum power draw supports practical thermal planning in enclosure-based installations.

Use Scenarios

Plant and facility network uplinks
In plant rooms, utility cabinets, and outdoor enclosures, operators often need to connect a remote ethernet switch or access equipment over long-distance fiber where copper runs are not practical. This transceiver serves as the optical link between switches, giving industrial teams a stable way to extend traffic across up to 40km while the temperature-rated versions help it fit installation areas where heat, cold, or limited airflow can affect normal modules.

OEM replacement and service stocking
For distributors, resellers, and maintenance teams supporting industrial ethernet switch manufacturers and network equipment fleets, spare parts must be easy to identify, stock, and deploy when a link module fails. This transceiver fits that need because it uses a standard LC connection, includes digital diagnostics for status checks, and is specified for consistent use in equipment builds centered on poe switch and fiber-connected network switch deployments.

FAQ

Q1. What devices and ports is this transceiver compatible with?
This sfp module is a Cisco compatible 1000BASE-BX-D BiDi unit for 1.25Gb/s data links. It uses a single LC connector and is intended for SMF deployments. For system integration, we recommend confirming port support on your network switch before installation.

Q2. What distance can I achieve with this module?
Rated performance reaches up to 40km on 9/125 µm single-mode fiber. The module uses a 1550nm DFB transmitter and a 1310nm PIN receiver, with up to 21dB link budget stated in the product description. Our team supplies this for long-reach Ethernet applications.

Q3. What installation and power requirements should our engineers expect?
The unit is hot-pluggable and operates from a single +3.3V power supply, which supports practical field replacement in compatible systems. Digital diagnostics are available through the SFF-8472 2-wire serial interface, helping our operators monitor module status during service.

Q4. Can this be used in industrial or temperature-variable environments?
Yes, version options are listed for industrial, extended, and commercial operating ranges: -40 C to 85 C, -5 C to 85 C, and 0 C to 70 C. That makes it suitable for controlled cabinets and harsher installations where industrial ethernet switch manufacturers specify stable optical components.

Q5. What compliance and maintenance details are available for procurement teams?
RoHS compliant and lead free, this transceiver is designed with a maximum power of 1W. Standard diagnostics via SFF-8472 support routine checks, and our buyers can use those readings to verify operating condition without removing the module from the system.
