◆ Description:

Miray’s GE-LX40-SM1310 Transceiver is a high performance, cost effective module which have a duplex LC optics interface. Standard AC coupled CML for high speed signal and LVTTL control and monitor signals. The receiver section uses a PIN receiver and the transmitter uses a 1310 nm DFB laser, up to 22dB link budge ensure this module 1000Base Ethernet 40km application.

Reliable 40km Fiber Reach for Network Expansion
This Cisco compatible sfp module is built to extend Ethernet connections across longer distances with a stable 1000BASE-LH design, supporting up to 1.25Gb/s data links and up to 40 km over 9/125 μm SMF. With a 1310nm DFB laser transmitter, PIN receiver, duplex LC optics interface, and hot-pluggable design, it gives procurement teams and system builders a practical option for deployments where standard copper links are not enough. For ethernet switch installations in offices, campuses, industrial facilities, and service networks, it provides the reach and interface flexibility needed to connect remote points with fewer constraints on cable distance.

Built for Monitoring, Power Efficiency, and Stable Operation
The module includes single +3.3V power supply support, a monitoring interface compliant with SFF-8472, and a maximum power draw of 1W, helping operators maintain visibility and control within managed infrastructure. Its compliance-driven design supports reliable integration with hardware from top network switch manufacturers, and it is well suited for teams working with network switch platforms that require consistent transceiver behavior under defined electrical and optical conditions. Available in industrial, extended, and commercial temperature ranges from -40°C to 85°C, -5°C to 85°C, or 0°C to 70°C, it offers deployment flexibility for environments where operating conditions vary and equipment stability matters.

Practical Fit for Industrial and Managed Ethernet Environments
For industrial ethernet switch manufacturers, optical transceiver manufacturers, distributors, and integration teams, this transceiver supports a broad set of application needs where long-reach fiber connectivity is required. It is RoHS compliant and lead free, making it suitable for regulated supply chains and projects that prioritize responsible material choices. Whether it is used in an ethernet switch, a poe switch, or another managed network switch platform, the module offers a dependable way to connect remote endpoints, upgrade existing optical ports, and maintain compatibility in systems that depend on consistent optical performance and controlled deployment planning.

Key Advantages

Stable Optical Performance for Long-Distance Links
This sfp module supports up to 1.25Gb/s data links and delivers reliable transmission over 40 km on 9/125 μm SMF, which makes it a practical choice for teams that need consistent connectivity across extended network spans. The 1310nm DFB laser transmitter and PIN receiver are built for stable signal handling, while the duplex LC interface and DOM support help optical transceiver manufacturers, system integrators, and industrial ethernet switch manufacturers maintain accurate link monitoring and easier fault checking in ethernet switch deployments.

Industrial-Friendly Design for Easier Deployment and Maintenance
With a single +3.3V power supply, hot-pluggable design, and maximum power of 1W, this transceiver is practical for equipment that must stay serviceable with less interruption. Its compliance with SFF-8472, RoHS, and lead-free requirements supports structured procurement for top network switch manufacturers, poe switch builders, and network switch maintenance teams, while the available industrial, extended, and commercial temperature ranges make it well-suited for installations that need dependable operation in varied environments.

Use Scenarios

Factory and Plant Network Uplinks
In industrial plants, warehouses, and other controlled production areas, operators often need to connect a remote ethernet switch or control cabinet to a central rack over a long distance without losing link stability. This transceiver acts as the optical layer between switches, supporting 40 km transmission and DOM monitoring so plant engineers can verify link condition during deployment and routine checks. Its temperature-rated versions make it a practical fit for installations specified by industrial ethernet switch manufacturers and maintenance teams working around machinery and electrical cabinets.

Carrier, Campus, and Equipment Integration Projects
For network upgrades in campuses, service rooms, and multi-building sites, procurement teams and integrators need an sfp module that fits existing optical ports and supports predictable long-reach connectivity between a network switch and upstream or downstream equipment. This transceiver is well-suited to that role because the LC duplex interface, hot-pluggable design, and 1310nm operation help simplify replacement and expansion work. It also supports system builds from top network switch manufacturers and OEMs that require stable optical links for structured fiber deployments.

FAQ

Q1. Is this SFP module compatible with a 1000BASE-LH Ethernet application?
Yes, this module is designed for 1000BASE Ethernet over single-mode fiber and supports up to 1.25Gb/s data links. The duplex LC interface and 1310nm DFB transmitter make it suitable for long-reach network switch deployments where a stable sfp module is required.

Q2. What distance can I expect over single-mode fiber?
