What is the white fiber optic cold connector

A fiber optic cold connector (white) is a field-installable mechanical connector that terminates fiber optic cables without fusion splicing, offering fast, reliable, and reusable connections.

Overview

A fiber optic cold connector, also known as a mechanical splice or fast connector, allows for quick termination of fiber optic cables without the need for epoxy, polishing, or heating . The connector aligns the bare fiber with a short fiber stub inside the connector body using index-matching gel or mechanical clamping, enabling efficient optical signal transmission . White-colored connectors are available for aesthetic or coding purposes and are commonly used in indoor FTTH deployments .

Types and Specifications

  • SC/APC Cold Connector: Features an 8-degree angled endface polish, providing return loss ≥60dB, ideal for GPON, EPON, and CATV networks where low back reflection is critical .
  • SC/UPC Cold Connector: Uses ultra-physical contact polish with return loss ≥50dB, suitable for general FTTH applications .
  • Material: Many connectors use PEI (polyetherimide) for the body, offering high temperature resistance (-40℃ to 75℃), fire retardance, and wear resistance .
  • Performance: Typical insertion loss is <0.3dB, and connectors can be reused up to 1000 times .

Applications

  • FTTH Deployments: Terminating drop cables at customer premises, patching within distribution boxes, and emergency repairs .
  • Small-scale or rapid installations: Ideal for situations where fusion splicing is impractical or time-consuming .
  • Indoor and outdoor LANs: Compatible with both single-mode and multimode fibers .

Installation Process

  1. Strip the fiber coating and clean the bare fiber with alcohol .
  2. Insert the fiber into the connector body and align it with the internal fiber stub .
  3. Clamp and lock the fiber using the connector's mechanical mechanism .
  4. Install the SC housing and secure the dust cap . No specialized fusion splicing equipment is required, making installation faster and more convenient for field technicians .

Purchasing Options

White fiber optic cold connectors are available from electronics distributors like Mouser Electronics and online marketplaces such as Amazon . They are sold individually or in bulk packs, often including SC/APC or SC/UPC variants suitable for FTTH projects. In summary, a white fiber optic cold connector provides a fast, reliable, and reusable solution for terminating fiber optic cables in field installations, particularly in FTTH networks, without the need for complex splicing equipment .
