Optical Fiber Accessories (Adapters & Patch Cords)

Optical fiber adapters and patch cords for structured fiber networks, covering ST, SC, LC, FC and MTRJ connector types.

Key Features

Connector coverage, fiber mode options and build quality of our fiber accessories line.

ST/SC

Full Connector Type Range

ST, SC, SC Duplex, LC, LC Duplex, FC and MTRJ Duplex adapters cover most fiber network connector standards.

SM/MM

Singlemode & Multimode Patch Cords

ST-ST, SC-SC and FC-FC singlemode patch cords, plus LC-LC and MTRJ-MTRJ multimode duplex patch cords.

LOSS

Low Insertion Loss

Precision connector ferrules minimize signal loss at every patch and cross-connect point.

PGTL

Fan-Out Pigtail Assemblies

Multi-fiber, color-coded pigtail bundles for splice tray and patch panel termination.

DUR

Field-Ready Durability

Connector housings built for repeated mating cycles in data center and telecom cross-connect environments.

CFG

Custom Length & Connector Combinations

Patch cords built to your required length and connector-type pairing.

OEM & ODM Capabilities

Custom connector combinations, length, fiber count and packaging tailored to your project.

CONN

Custom Connector Combination

Mix connector types on either end (e.g. SC-LC, ST-SC) to match your patch panel and equipment ports.

LEN

Custom Length

Patch cords produced to your required length, from short jumpers to long cross-connect runs.

CNT

Custom Pigtail Fiber Count

Fan-out pigtail bundles produced in your required fiber count for splice tray termination.

PKG

Custom Packaging

Bulk bagged, boxed or reel packaging tailored to your installation and logistics requirements.

LOGO

Custom Branding & Marking

Customer logo and cable surface marking printed to your brand specification.

MOQ

Sampling & Volume Production

Small-batch sampling for qualification followed by scalable volume production once specifications are confirmed.

Construction & Configuration

How fiber core, ferrule, connector housing and jacket come together in each patch cord.

KEXINGYU fiber connector construction diagram ferrule housing boot
1

Fiber Core — Singlemode or Multimode

Patch cords are built on singlemode or multimode fiber core to match the connector product line.

2

Connector Ferrule

A precision ferrule aligns and polishes the fiber end-face for low-loss mating at each connector.

3

Connector Housing — ST / SC / LC / FC / MTRJ

Connector housings are built to the ST, SC, LC, FC or MTRJ standard footprint for equipment and patch panel ports.

4

Cable Jacket — Mode Color Coding

Jacket color follows industry convention: yellow for singlemode, orange for multimode, for quick visual identification.

5

Simplex or Duplex Configuration

Single-fiber (simplex) or two-fiber (duplex) cable configuration depending on the connector pairing.

6

Boot & Strain Relief

A color-coded connector boot protects the fiber from bending stress at the termination point.

Standards & Test Documentation

Connector compatibility, fiber mode color coding and where to get full datasheets.

Connector Compatibility

ST / SC / LC / FC / MTRJ

Adapters and patch cords cover the ST, SC, SC Duplex, LC, LC Duplex, FC and MTRJ Duplex connector standards.

Fiber Mode Color Coding

Yellow / Orange Convention

Cable jackets follow the industry convention of yellow for singlemode fiber and orange for multimode fiber.

Documentation

Datasheet on Request

Connector-specific insertion loss, return loss and dimensional data available on request.
