HELOS OS2 Single-Mode 9/125μm Duplex Fiber Patch Cable, E2000® APC to LC, LSZH Yellow, 7.5m

With a return loss of ≥60 dB on the APC connector, this HELOS patch cable practically eliminates back reflections, ensuring signal integrity in the most demanding single-mode links. The E2000® APC (LSH) connector features an integrated spring-loaded shutter that protects the ferrule from dust and laser radiation, while the LC duplex connector provides a compact, high-density connection. The 9/125μm OS2 fiber is optimized for wavelengths from 1310 nm to 1550 nm, supporting high-speed data transmission over long distances. The LSZH yellow jacket is flame-retardant and low-smoke, making it safe for use in enclosed spaces. Each cable is individually tested for insertion loss (≤0.25 dB) and return loss, and comes with a test report for quality assurance.

Overview

This HELOS fiber optic patch cable is engineered for reliable performance in data centers, telecommunications networks, and FTTx applications. It features a duplex configuration with two single-mode fibers, allowing bidirectional communication over a single cable assembly. The E2000® APC connector on one end provides superior return loss performance, while the LC connector on the other end offers a small form factor for high port density. The cable is 7.5 meters long, providing flexibility in equipment layout. The yellow jacket indicates single-mode fiber, and the LSZH material meets strict fire safety standards.
