In a high-precision manufacturing facility, control cabinets are dispersed across multiple production zones with ambient temperatures ranging from –40 °C to +85 °C. Deploying the SRX-SFP-1GE-LH-ET small form factor pluggable 1000Base-LH Gigabit Ethernet optic module over single-mode fiber ensures reliable, low-latency communication between PLCs and SCADA hosts up to 10 km apart. Benefit: Maintains consistent gigabit performance in extreme temperatures, minimizes unplanned downtime, and supports real-time process control with enterprise-grade fiber resilience.
A multi-building data center campus requires a scalable, cost-effective backbone link to carry server-to-storage traffic across a 9 km campus ring. Integrating SRX-SFP-1GE-LH-ET 1000Base-LH modules in top-of-rack switches delivers seamless gigabit Ethernet connectivity over existing single-mode fiber infrastructure. Benefit: Delivers predictable 1 Gbps throughput under extended-temperature conditions, reduces fiber splicing complexity, and enables modular upgrades without replacing legacy cabling.
In an offshore drilling platform and adjacent onshore pumping stations, network nodes face salt spray, temperature swings, and vibration. The SRX-SFP-1GE-LH-ET SFP module provides hardened 1000Base-LH links over long-haul single-mode fiber, connecting environmental sensors and SCADA systems up to 10 km away. Benefit: Ensures continuous data acquisition in –40 °C to +85 °C environments, reduces maintenance visits, and strengthens industrial IoT telemetry with carrier-grade optical reliability.

The SRX-SFP-1GE-LH-ET is a Small Form-factor Pluggable (SFP) 1000Base-LH Gigabit Ethernet transceiver designed for long-haul data transmission over single-mode fiber.
This module supports data transmission up to 10 kilometers over single-mode fiber.
The SRX-SFP-1GE-LH-ET operates at a nominal wavelength of 1310 nm.
It operates reliably from ‑40 °C to +85 °C (extended industrial temperature range).
It is compatible with single-mode (SMF) fiber with an 8.3/125 µm core/cladding diameter.
Yes, the module is hot-swappable, allowing insertion or removal without powering down the host device.
It is MSA-compliant and works with most switches, routers, and media converters that support 1000Base-LH SFP ports.
Align the module with the SFP slot, insert until it clicks, then connect appropriate LC single-mode fiber cables.
Typical power consumption is 1.0 W, not exceeding 1.2 W under full load.
No, it uses a standard SFP interface and requires no additional drivers or firmware.
It meets CE, FCC, RoHS, and UL Class I Div 2 standards for safety and electromagnetic compatibility.
Check the link/activity LED on the host device and use optical power meters or built-in diagnostics (DOM) to confirm performance.
Both operate at 1310 nm, but 1000Base-LH optimizes extended temperature and longer reach up to 10 km.
No, using it on multi-mode fiber may cause significant loss; single-mode fiber is required.
It includes a two-year limited warranty covering manufacturing defects under normal use.
