◆ Description:

Miray’s 2.5G-LX40-SM1310 Transceivers are a high performance, cost effective module which have a duplex 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 APD receiver and the transmitter uses a 1310 nm DFB laser, up to 25dB link budge ensure this module SONET OC-48 / SDH STM -16 40km application.

High-Speed Optical Reach for Carrier and Enterprise Networks
This 2.5G SFP OC48 STM-16 SMF 1310nm 40KM SFP transceiver module is built to extend reliable optical connectivity across demanding network environments where stable throughput and predictable performance matter. Supporting up to 2.67Gb/s data links, it gives procurement teams, system integrators, and network operators a practical option for upgrading an ethernet switch, network switch, or poe switch deployment with a compact sfp module designed for long-distance single-mode fiber links. The hot-pluggable format and duplex LC interface make it well suited to rack-level maintenance and field replacement, while the 1310nm DFB transmitter and APD receiver architecture support transmission up to 40km over 9/125 μm SMF, helping teams maintain dependable interconnection between sites, aggregation layers, and transport equipment without unnecessary complexity.

Built for Operational Reliability and System Visibility
Engineered for real-world deployment, this transceiver runs from a single +3.3V power supply and includes a monitoring interface compliant with SFF-8472, giving technical teams better visibility into module status during installation and operation. With a maximum power consumption of 1W, it fits efficiently into dense switch environments where thermal load and power budgets are important considerations for industrial ethernet switch manufacturers, optical transceiver manufacturers, and other hardware providers integrating optical interfaces into managed platforms. The module is also available across industrial, extended, and commercial temperature ranges, including -40°C to 85°C, -5°C to 85°C, and 0°C to 70°C versions, which makes it suitable for installations that must perform consistently in controlled rooms, roadside cabinets, and other variable operating conditions. RoHS compliance and lead-free construction further support procurement requirements for regulated and environmentally conscious supply chains.

Practical Fit for Network Builds, Upgrades, and Distribution
For buyers supporting enterprise backbones, access aggregation, or industrial communications, this transceiver offers a balanced mix of reach, compatibility, and installation convenience. It is a practical choice for top network switch manufacturers, distributors, resellers, and integrators looking to stock a dependable optical interface for platform builds, replacement parts, or customer upgrades where a 2.5G-class transceiver is required. In mixed network environments, it can support link extensions between an ethernet switch and remote equipment over single-mode fiber, helping teams maintain organized deployments with fewer compromises on distance or thermal performance. Whether used in factory networks, telecom rooms, or enterprise transport segments, this module provides a stable option for applications that need a verified optical path, efficient serviceability, and a form factor that works naturally with standard SFP slots.

Key Advantages

Stable Optical Performance for Carrier-Grade Links
This sfp module supports up to 2.67Gb/s data links and uses a 1310nm DFB laser with an APD receiver, which gives procurement teams and system integrators a practical choice for long-distance transmission where signal consistency matters. Its support for up to 40km on 9/125 μm SMF helps maintain dependable connectivity in backbone and uplink deployments, making it well suited for ethernet switch and network switch installations that must hold performance over distance.

Industrial Compatibility and Maintenance Efficiency
With a hot-pluggable duplex LC connector, single +3.3V power supply, and monitoring interface compliant with SFF-8472, this transceiver is built for easier installation and routine status checks in managed networks. The availability of industrial, extended, and commercial temperature versions gives optical transceiver manufacturers, industrial ethernet switch manufacturers, and top network switch manufacturers a practical module option for systems that need stable operation in varied environments, while RoHS compliance and lead-free construction support cleaner procurement requirements.

Use Scenarios

Telecom and Campus Network Uplinks
In telecom rooms, campus backbone cabinets, and equipment racks where operators need a stable optical link between switches across long distances, this module serves as the transceiver interface that carries traffic between ports without adding unnecessary complexity. Its 40km single-mode reach and duplex LC design make it well suited for network switch and ethernet switch uplinks where the main need is reliable transport between buildings or across large facilities.

Industrial Network Integration
In factories, utility sites, and outdoor enclosures where temperature variation and maintenance access can be challenging, plant engineers and integrators need components that support predictable operation and straightforward replacement. This sfp module fits that role by combining hot-pluggable handling, industrial temperature options, and monitoring support, which helps it work well in poe switch and managed switch deployments where uptime and serviceability are important for day-to-day operations.

FAQ

Q1. What network applications is this transceiver module suited for?
It is designed for 2.5G data links up to 2.67Gb/s and supports OC48/STM-16 transmission over single-mode fiber. With a 1310nm DFB laser and APD receiver, our sfp module is well-suited for telecom and carrier-grade network switch integration.

Q2. What fiber and connector requirements does it have?
