Description

Black Box EFN310-003M-LCLC OS2 Singlemode Fiber Optic Patch Cable

Overview

The Black Box EFN310-003M-LCLC is a 3-meter OS2 9/125 singlemode fiber optic patch cable. It terminates with LC connectors on both ends, providing a reliable physical link for optical signals. This cable is critical for extending network connectivity between network devices, such as media converters, switches, or transceivers, over longer distances than copper Ethernet can support, particularly in environments requiring high bandwidth and immunity to electromagnetic interference, like industrial surveillance deployments.

Compatibility

This OS2 singlemode fiber optic patch cable is compatible with any network equipment utilizing LC (Lucent Connector) style singlemode fiber ports. This includes, but is not limited to, SFP/SFP+ transceivers, media converters, and network switches from various manufacturers that support singlemode fiber transmission. It is designed for use with 9/125 micron fiber optic cabling infrastructure.

Installation Notes

Handle fiber optic connectors with care to avoid contamination and damage. Use appropriate cleaning tools before connecting. Ensure the bend radius of the cable does not exceed its specifications to maintain signal integrity. The black color aids in distinguishing it from other cable types in a dense rack environment.
