◆ Description:

Miray’s GE-BX20-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 14dB link budge ensure this module 1000Base-LX Ethernet 20km application.

Long-Range BiDi Connectivity for Stable Network Expansion
This 1.25Gb/s 1000BASE-BX BiDi SFP module is built to give network teams a practical way to extend an ethernet switch or network switch connection over single-mode fiber without adding unnecessary complexity. Using a 1550nm TX / 1310nm RX design with an LC connector, it supports up to 20km transmission on 9/125 μm SMF, making it a strong fit for plant links, campus backbones, and remote equipment rooms where consistent optical performance matters. For industrial ethernet switch manufacturers, top network switch manufacturers, and system integrators, this sfp module offers a dependable option when a compact, single-fiber transceiver is needed for practical deployment and long-distance point-to-point connectivity.

Built on Proven Optical Components and Monitoring Support
The module combines a 1550nm DFB laser transmitter with a 1310nm PIN photo-detector to deliver stable data links up to 1.25Gb/s, while the hot-pluggable design helps simplify installation and replacement during maintenance windows. It follows the SFF-8472 specification and includes digital diagnostics through the 2-wire serial bus, giving operators and procurement teams better visibility into module status and link health. With a single +3.3V power supply and maximum power consumption of 1W, this transceiver is well suited to systems that need efficient operation and predictable integration. As a result, optical transceiver manufacturers, poe switch solution builders, and industrial networking teams can rely on it as a controlled, standards-aligned component for scalable infrastructure.

Practical Fit for Industrial and Commercial Deployment
Available in industrial, extended, and commercial temperature versions, this BiDi SFP is designed to support real operating conditions ranging from -40°C to 85°C, -5°C to 85°C, or 0°C to 70°C depending on the version selected, which makes it suitable for outdoor cabinets, factory floors, telecom rooms, and other environments where thermal range is a key buying factor. RoHS compliance and lead-free construction also make it easier for distributors, resellers, and procurement teams to align with current compliance requirements. For buyers sourcing components for an ethernet switch, network switch, or industrial communication platform, this module delivers a practical balance of reach, diagnostics, and environmental tolerance that supports reliable system design and long-term deployment.

Key Advantages

Stable 1.25Gb/s Link Performance
This sfp module is built for 1.25Gb/s data links and supports up to 20km over 9/125 μm single-mode fiber, which gives procurement teams and system integrators a practical option for long-range ethernet switch and network switch deployments. The 1550nm DFB transmitter and 1310nm PIN receiver are designed for consistent optical performance, helping reduce link instability in fixed installations where uptime matters.

Practical Maintenance and Compatibility
With a hot-pluggable single LC interface, this module is easier to install and replace during service work, which supports maintenance planning for operators of poe switch and industrial network systems. Compliance with SFF-8472 monitoring allows teams to check operating status through the serial interface, and the single +3.3V supply with RoHS-compliant lead-free construction makes it a practical choice for buyers working with industrial ethernet switch manufacturers, optical transceiver manufacturers, and top network switch manufacturers.

Use Scenarios

Factory and Plant Network Uplinks
In industrial plants and production areas, teams often need a stable fiber link between a control room and remote equipment room where electrical noise and distance can affect copper connections. This transceiver module serves as the optical link inside an ethernet switch or network switch setup, providing long-distance transmission over single-mode fiber and helping keep communication between controllers, monitoring systems, and field devices reliable in temperature-demanding environments.

Equipment Integration for Network Hardware Builds
For OEMs, panel builders, and distributors assembling switch platforms, a compact sfp module is needed when the design calls for a verified 1000BASE-BX BiDi optical path with simple LC cabling. This module fits that role because it supports monitoring, hot-swap service, and industrial operating ranges, making it well-suited for product lines from industrial ethernet switch manufacturers and network hardware teams that need a practical fiber option for poe switch and standard switch configurations.

FAQ

Q1. What applications is this transceiver module suited for?
It is designed for 1.25Gb/s data links and 1000BASE-BX use over up to 20km on 9/125 μm single-mode fiber. With a single LC interface, it is well suited for ethernet switch and network switch deployments where a compact BiDi optic is required.

Q2. What optical configuration does it use?
This unit uses a 1550nm DFB laser transmitter on the TX side and a 1310nm PIN photo-detector on the RX side. That BiDi arrangement supports single-fiber operation through an LC connector, which we supply for stable integration in standard SFP slots.

Q3. What power and monitoring features are available?
The module runs from a single +3.3V power supply and includes a monitoring interface compliant with SFF-8472. Our diagnostics support makes it practical for operators and maintenance teams that need module status visibility during deployment and routine checks.

Q4. Can this module operate in industrial environments?
Yes, we offer versions for industrial, extended, and commercial temperature ranges: -40°C to 85°C, -5°C to 85°C, and 0°C to 70°C. This gives procurement teams and system integrators flexibility when selecting a fit for controlled rooms or harsher sites.

Q5. Is this transceiver compatible with common procurement and deployment needs?
The module is hot-pluggable, RoHS compliant, and lead free, with a maximum power of 1W. We position it for practical use in optical transceiver manufacturers, industrial ethernet switch manufacturers, and teams sourcing an sfp module for poe switch or network builds.
