• Long-haul versatility with 40 km reach: The Accortec 1000BASE-LH40 SFP Transceiver is purpose-built for extended fiber runs. With a transmission distance of up to 40 kilometers on single-mode fiber, it enables campus-to-campus links, data-center interconnects, and remote site connectivity without the need for repeaters or amplifiers. This capability helps you design scalable networks that accommodate growth, reduce the number of active network hops, and simplify maintenance across distributed locations. The 1310 nm laser wavelength optimizes signal integrity over long distances and minimizes dispersion effects, delivering stable, reliable performance for backbone and distribution layers. Whether you’re linking data centers, connecting regional offices, or creating disaster-recovery paths, this SFP module provides the backbone you need for dependable, high-bandwidth access.
• 1 Gbps Ethernet over single-mode fiber with broad compatibility: This transceiver supports 1000BASE-LH40, delivering a full-duplex 1 Gbps link over OS2 single-mode fiber. Its compatibility with a wide range of switches, routers, and media converters makes it a flexible option for mixed-vendor environments, enabling seamless uplinks and downlinks across different devices. The SFP form factor ensures easy hot-swapping in standard SFP-enabled ports, reducing downtime and simplifying maintenance windows. With multi-source compatibility, you can rely on consistent performance while aggregating traffic from servers, storage systems, IP phones, and other networked devices, all while preserving your existing cabling infrastructure.
• Low power design, high reliability, and easy deployment: Accortec’s SFP modules prioritize energy efficiency without compromising performance. The compact transceiver consumes modest power, producing less heat and improving data-center cooling efficiency. Its hot-swappable capability minimizes disruption—simply eject the existing module, slide in the LH40 SFP, and re-establish the link with minimal downtime. The robust build quality provides dependable operation in typical data-center and enterprise environments, delivering steady performance in both steady-state loads and peak traffic periods. Expect fewer interruptions, quicker maintenance cycles, and a smoother path to network modernization as older links are upgraded to 1000BASE-LH40.
• Built for durability and environmental resilience: The Accortec LH40 SFP is designed to withstand the rigors of real-world deployments. Its rugged optical components, stable mechanical fit, and reliable signal integrity under a range of operating conditions help you avoid common transmission issues such as fiber bend loss, connector degradation, and micro-bending. While the module is optimized for standard data-center temperatures, its engineering emphasizes continued operation in challenging campus environments and edge locations, where reliable fiber performance is critical for mission-critical workloads, backups, and real-time data replication. This translates into fewer field service calls and more consistent network performance across sites.
• Diagnostics, monitoring, and easy management: Many Accortec SFP modules support Digital Optical Monitoring (DOM), enabling real-time visibility into optical power, temperature, and other critical parameters through compatible network equipment. This capability helps network engineers quickly identify link quality issues, anticipate maintenance needs, and verify that the transceiver operates within specified tolerances. DOM instrumentation supports proactive management, faster fault isolation, and better capacity planning—especially in densely populated data centers or multi-site networks where uptime and performance are paramount. The LH40 module’s monitoring features empower you to optimize performance and maintain service levels with greater confidence.

How to install Accortec 1000BASE-LH40 SFP Transceiver Module

• Preparation: Ensure your network device (switch, router, or media converter) supports 1000BASE-LH SFP modules and that the port is powered off or in a maintenance window before installation. Verify cable specifications for single-mode OS2 fiber and confirm connector types (LC duplex) match the transceiver and the fiber link.
• Power down the device (optional for some environments): In high-availability environments, plan a brief maintenance window. For most deployments, hot-swapping is supported, but it’s prudent to power down if you are uncertain about the device’s hot-swap capabilities.
• Insert the transceiver: Align the LH40 SFP with the device’s SFP slot and gently slide it in until it seats with a distinct click. Ensure the module’s metal shield is flush with the device faceplate and that the retention latch is engaged if applicable. Avoid excessive force to prevent damage to the slot or module.
• Connect the fiber optic cable: Attach a high-quality LC duplex single-mode fiber patch cord to the transceiver, ensuring clean, dust-free connectors. Tighten ferrules and confirm the cable is properly routed to prevent strain or bend radii that could degrade signal quality. Avoid sharp bends and keep fiber paths organized for serviceability.
• Power on and verify: Restore power to the device (if powered down) and check link status indicators. Use the device’s management interface to verify that the transceiver is recognized and that the link is establishing at 1 Gbps. If your equipment supports DOM, review optical power levels and signal integrity to confirm stable operation over time.
• Test and monitor: Run a basic throughput test between endpoints to confirm end-to-end connectivity and measure latency, jitter, and error rates. If you encounter issues, consult the device logs, check fiber integrity, and confirm that the correct transceiver type is installed in the appropriate SFP port. Maintain a record of the transceiver’s serial and lot information for future reference and warranty purposes.
