Genuine Huawei 155M Fast Ethernet eSFP Single-Mode Transceiver 1310nm 40km S4015715 eSFP-FE-LH40-SM1310

This is an original Huawei 155M Fast Ethernet long-reach eSFP single-mode optical transceiver module (Huawei Part Number / BOM: S4015715, Model: eSFP-FE-LH40-SM1310). Housed in a hot-pluggable eSFP (Enhanced SFP) form factor with digital diagnostics, this legacy transceiver operates at a nominal wavelength of 1310nm. It is purpose-built to deliver continuous Fast Ethernet signaling over Single-Mode Fiber (SMF) infrastructure for mid-to-long range spans up to 40 kilometers (40km) without intermediate regeneration points.

Typical Applications

✅Enterprise WAN Interconnection

 Ideal for low-speed data backhaul across campuses or buildings.

✅Metro Access Networks

 Serves as a last-mile access module connecting remote base stations or small offices.

✅SONET/SDH Transport Networks

 Fully compatible with legacy TDM equipment, supporting OC-3/STM-1 rates.

✅Industrial Control & Security: Suited for surveillance and PLC communications where high bandwidth is not required but long distance is critical.

Product Highlights

✨100% Huawei Native Firmware Engineering

 Factory-certified assembly guarantees native configuration discovery. Unlike generic aftermarket modules prone to optical clock drift, this authentic hardware secures seamless synchronization across critical 40km industrial spans.

✨Cost-Effective Legacy System Upkeep

 Tailored for utilities and ISPs needing to sustain existing Fast Ethernet architectures without committing to expensive, full-scale Gigabit hardware retrofits.

✨Precision Telemetry Diagnostics

  Integrated DDM lets field engineers identify fiber degradation patterns over long distances directly from the central dashboard, reducing field labor costs and optimizing network uptime (SLA).
