What Is the Difference Between LC, SC, FC and MPO Fiber Optic Patch Cords? How to Choose?

Created on 09.07
When purchasing fiber optic patch cords, customers often encounter different types of fiber optic connectors, such as LC, SC, FC, and MPO/MTP.
These connectors differ in size, structure, connection method, and application. Therefore, when selecting a fiber optic patch cord, it is important to consider the equipment interface, installation space, and specific application requirements.

LC Fiber Optic Patch Cord

LC is one of the most widely used compact fiber optic connector types.
The LC connector has a small form factor and is suitable for high-density installations. It is widely used in data centers, server racks, network switches, and fiber optic distribution systems.
Common LC patch cord configurations include:
  • LC-LC fiber optic patch cords;
  • LC-SC fiber optic patch cords;
  • LC-FC fiber optic patch cords;
  • LC/APC fiber optic patch cords;
  • LC/UPC fiber optic patch cords.
For applications where a large number of fiber connections need to be installed in limited space, LC connectors are often an excellent choice.

SC Fiber Optic Patch Cord

SC is a classic fiber optic connector that uses a push-pull connection mechanism.
The SC connector is larger than the LC connector, but it has a simple structure and is easy to install and operate. It is still widely used in telecommunications networks, FTTH systems, and fiber optic distribution systems.
Common SC patch cord configurations include:
  • SC-SC;
  • SC-LC;
  • SC-FC;
  • SC/APC;
  • SC/UPC.
SC/APC fiber optic patch cords are commonly used in FTTH and PON applications.

FC Fiber Optic Patch Cord

FC connectors use a threaded locking mechanism, providing a secure and stable mechanical connection.
FC fiber optic patch cords are commonly used in telecommunications equipment, testing equipment, and applications where reliable connector fixation is important.
Common configurations include:
  • FC-FC;
  • FC-LC;
  • FC-SC;
  • FC/APC;
  • FC/UPC.
If the equipment uses an FC interface, a compatible FC fiber optic patch cord should be selected.

MPO/MTP Fiber Optic Patch Cord

MPO/MTP is a multi-fiber, high-density fiber optic connectivity solution. Unlike traditional single-fiber connectors such as LC and SC, MPO/MTP connectors can integrate multiple fibers into a single connector.
MPO/MTP fiber optic patch cords are suitable for high-density and high-bandwidth network environments.
Typical applications include:
  • Data centers;
  • High-speed Ethernet networks;
  • Fiber optic backbone connections;
  • High-density fiber distribution systems;
  • Connections between servers and network switches.
As data centers continue to require higher bandwidth and greater cabling density, MPO/MTP fiber optic solutions are becoming increasingly important.

How to Choose Between LC, SC, FC and MPO/MTP?

The following table provides a simple reference:
Connector
Main Features
Typical Applications
LC
Compact size, high density
Data centers, network switches
SC
Simple structure, easy connection
FTTH, telecommunications
FC
Threaded locking, secure connection
Telecommunications, testing equipment
MPO/MTP
Multi-fiber, high density
Data centers, high-speed networks
When selecting a fiber optic patch cord, you should also consider the fiber type, connector end-face type, and equipment interface.
For example:

Data Centers

Data center applications commonly use LC and MPO/MTP connectivity solutions together with multimode fibers such as OM3, OM4, and OM5.

FTTH/PON

For FTTH and PON networks, the appropriate connector should be selected according to the equipment interface and network architecture. SC/APC and LC/APC are commonly used options.

Traditional Telecommunications Equipment

Depending on the equipment interface, FC, SC, or LC fiber optic patch cords can be selected.

A Fiber Optic Patch Cord Is More Than Just a Connector

When purchasing fiber optic patch cords, it is important not to focus only on the connector type.
You should also confirm the following specifications:
  • Single-mode or multimode fiber;
  • OS1, OS2, OM3, OM4, or OM5;
  • UPC or APC;
  • Simplex or duplex;
  • Cable length;
  • Insertion loss;
  • Return loss;
  • Cable jacket type;
  • Operating environment;
  • Customization requirements.
Fiber optic patch cords can be supplied in various configurations, such as LC/UPC, LC/APC, SC/UPC, and SC/APC, with different fiber types and cable lengths to meet specific project requirements.

Why Choose Custom Fiber Optic Patch Cords?

Different customers and projects have different network structures and installation requirements.
Some projects require standard-length fiber optic patch cords, while data centers, telecommunications systems, and industrial applications may require specific cable lengths, connector combinations, or special cable jackets.
Customized fiber optic patch cords can provide a better fit for the actual installation environment.
Solanm can customize fiber optic patch cords according to customer requirements, including:
  • Fiber type;
  • Connector type;
  • Cable length;
  • UPC/APC end-face;
  • Simplex/duplex configuration;
  • Fiber count;
  • Product labeling;
  • Packaging.
