◆ Description:

Miray’s GE-BX40-SM3149 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 DFB laser, up to 21dB link budge ensure this module 1000Base-EX Ethernet 40km application.

Purpose-Built Link Extension for Industrial and Carrier Networks
This sfp module is designed to help buyers extend Gigabit Ethernet links with a practical, long-reach optical connection that fits demanding access and backbone deployments. As a Cisco compatible 1000BASE-BX-U BiDi transceiver, it supports 1.25Gb/s data links over a single LC interface, making it a space-efficient choice for network switch environments where fiber ports are limited and stable connection quality matters. For teams sourcing from optical transceiver manufacturers or comparing options for an ethernet switch, this module offers a clear balance of reach, compatibility, and operational simplicity for field installations, managed network upgrades, and mixed-site rollouts.

Verified Optical Performance and Operational Monitoring
Built around a 1310nm DFB laser transmitter and 1490nm PIN photo-detector, the module is specified for up to 40km transmission on 9/125 μm single-mode fiber, with a maximum power draw of 1W and support for SFF-8472 diagnostics through a 2-wire serial interface. The hot-pluggable design and single +3.3V power supply make deployment practical for technicians working with poe switch backbones, aggregation layers, and service-provider access ports, while DOM monitoring helps maintenance teams track operating status and link health in real time. This level of control is especially valuable for industrial ethernet switch manufacturers, OEM system builders, and procurement teams that need dependable components with documented electrical and optical behavior rather than generic replacements.

Well-Suited for Long-Reach Deployment Across Diverse Network Builds
Available in industrial, extended, and commercial temperature versions, this transceiver is a strong fit for outdoor cabinets, plant-floor systems, telecom closets, and other environments where temperature tolerance and reliability affect uptime. Its RoHS-compliant, lead-free construction supports responsible sourcing, while the single-LC BiDi architecture helps simplify fiber planning in installations managed by top network switch manufacturers, resellers, contractors, and operators. Whether it is used to expand a transceiver inventory, support a new network switch deployment, or maintain legacy compatibility in an existing ethernet switch platform, the module gives teams a practical way to extend Gigabit connectivity with predictable performance and straightforward integration.

Key Advantages

Stable Link Performance for Long-Distance Fiber Builds
This sfp module is designed for 1.25Gb/s data links and supports up to 40km over 9/125 μm single-mode fiber, which makes it a practical choice for buyers who need reliable uplinks between a network switch and remote equipment. The 1310nm DFB transmitter, 1490nm PIN receiver, and DOM support help teams monitor operating status and keep the link within expected limits, reducing the risk of unexpected downtime in structured deployments.

Practical Compatibility for Managed Deployment and Maintenance
Built to match the SFP MSA and SFF-8472, this transceiver is well suited for use in systems supplied by top network switch manufacturers and integrated by optical transceiver manufacturers. The hot-pluggable LC interface and single +3.3V power supply make installation and replacement straightforward for operators working on an ethernet switch or poe switch, while the RoHS-compliant, lead-free design supports standard procurement requirements and long-term service planning.

Use Scenarios

Factory and Industrial Network Uplinks
In plant floors, utility rooms, and outdoor cabinets, industrial ethernet switch manufacturers and system integrators often need a fiber link that can carry traffic over longer distances while resisting routine maintenance issues. This transceiver fits that need by providing a stable 1000BASE-BX-U connection with DOM reporting and industrial temperature versions, so it can support links between control systems, remote access points, and aggregation switches where temperature variation and service access are real concerns.

Backhaul for Enterprise Switch Interconnects
When a buyer needs to connect an access ethernet switch or poe switch to a distribution network switch across separate wiring closets or building areas, the main problem is maintaining dependable fiber transport without changing the overall design. This module handles that role with a single LC connection and 40km reach, making it a well-suited option for resellers, contractors, and operators who need a practical replacement or expansion part for existing fiber-based switch installations.
