Product Details

An Optical Fiber Patch Cord (also called fiber jumper or patch cable) is a fundamental passive component for connecting optical devices in fiber-optic networks, featuring pre-terminated connectors at both ends.

Here’s a comprehensive introduction:
It is a short-length optical fiber (typically 0.5m–10m) with standardized connectors attached to each end. Its key role is to establish temporary or permanent optical connections between devices like transceivers, switches, patch panels, PLC splitters, and FAUs, facilitating signal transmission with minimal loss.

Key Components & Structure

Optical Fiber Core

The transmission medium, available in single-mode (SMF, 9/125 μm) for long-distance, high-bandwidth applications or multi-mode (MMF, 50/125 μm or 62.5/125 μm) for short-range, high-data-rate scenarios.

Cladding & Coating

Cladding (around the core) ensures total internal reflection, while a protective polymer coating prevents mechanical damage and moisture intrusion.

Strengthening Member

Materials like aramid yarn (Kevlar) or steel wire enhance tensile strength, resisting breakage during installation or handling.

Jacket

Outer sheath (PVC, LSZH, or OFNR/OFNP) provides additional protection and meets fire safety or environmental requirements.

Connectors

Pre-installed at both ends (e.g., SC, LC, ST, FC, MPO/MTP), polished (PC, UPC, or APC) to minimize insertion loss and return loss.

Critical Features

Low Insertion & Return Loss Typical insertion loss <0.3 dB, return loss >45 dB (UPC) or >60 dB (APC), ensuring signal integrity.

High Compatibility Standardized connectors and fiber types match global industry specifications, enabling universal use.

Mechanical Durability Reinforced structure withstands bending, twisting, and repeated plug-unplug cycles (≥1000 times).

Environmental Adaptability Operates stably in temperatures ranging from -40℃ to +85℃, suitable for indoor or outdoor use.

Flexible Configurations Customizable in length, fiber type (SMF/MMF), connector type, and jacket material to fit specific application needs.

Common Types & Classifications

By Fiber Type

Single-mode Patch Cord (for long-haul communication, PON networks) and Multi-mode Patch Cord (for data centers, LANs).

By Connector Type

SC-SC, LC-LC, SC-LC, ST-FC, MPO-MTP, and other customized configurations.

By Jacket Material

PVC (cost-effective, indoor use), LSZH (low smoke zero halogen, safe for public areas), and OFNR/OFNP (flame-retardant, for vertical/riser applications).

Typical Applications

Data Centers

Connect servers, switches, and storage devices to patch panels, supporting high-speed Ethernet (10G/40G/100G).

Telecommunication Networks

Link base stations, OLTs (Optical Line Terminals), and ONUs (Optical Network Units) in PON/FTTH systems.

Enterprise & Campus Networks

Facilitate connections between network hardware in offices or industrial facilities.

Test & Measurement

Used in fiber optic testing setups to verify signal performance, insertion loss, and network integrity.

Frequently Asked Questions

What is the primary function of an Optical Fiber Patch Cord?

An Optical Fiber Patch Cord is used to establish temporary or permanent optical connections between fiber-optic network devices such as transceivers, switches, patch panels, PLC splitters, and FAUs, facilitating signal transmission with minimal loss.

What is the structural difference between Single-mode and Multi-mode cores?

Single-mode fiber cores (SMF, 9/125 μm) are designed for long-distance, high-bandwidth applications. Multi-mode fiber cores (MMF, 50/125 μm or 62.5/125 μm) are suitable for short-range, high-data-rate scenarios.

What are the typical optical performance specifications for these patch cords?

They offer high signal integrity with a typical insertion loss of less than 0.3 dB, and return loss values greater than 45 dB for UPC connectors or greater than 60 dB for APC connectors.

Which jacket materials are available and how do they differ?

Jacket options include PVC (cost-effective for general indoor use), LSZH (low smoke zero halogen for public and safety-critical areas), and OFNR/OFNP (flame-retardant jackets designed for vertical riser applications).

How durable are Optical Fiber Patch Cords?

They feature a reinforced structure with strengthening members like aramid yarn (Kevlar) or steel wire, allowing them to withstand bending, twisting, and repeated plug-unplug cycles of 1000 times or more.

In what environments can these patch cords operate?

They have high environmental adaptability and can operate stably in temperatures ranging from -40℃ to +85℃, making them suitable for both indoor areas (data centers, offices) and outdoor telecom cabinets.
