What are fiber optic connectors?

Fiber optic connectors are crucial components in fiber optic networks, designed to align and join fiber cables with precision. Here’s an overview of their characteristics and components:

Precision Requirements:

Unlike electrical cable connectors, fiber optic connectors must align microscopic glass fibers with high accuracy to ensure effective light signal transmission.

Design Variations:

While there are numerous types of fiber connectors, they generally share key design features. One fundamental distinction is between simplex (one connector per end) and duplex connectors (two connectors per end).

Major Components:

  • Ferrule: This is often a cylindrical part that securely holds the glass fiber. Made of ceramic, metal, or high-quality plastic, it features a hollowed-out center to grip a single strand of fiber tightly.
  • Connector Body: Made of plastic or metal, this structure houses the ferrule and connects to the fiber cable’s jacket and strength members.
  • Coupling Mechanism: Part of the connector body, it secures the connector when attached to another device, like a switch, network interface card (NIC), or bulkhead coupler. The mechanism might be a latch clip, bayonetstyle nut, or a similar device.

Types of the fiber optic connectors

There are more than one hundred types of fiber optic connectors, each designed for specific uses and characteristics. Here are some of the most common types:

SC (Standard Connector):

A push-pull connector that is widely used due to its durability and low-cost. It’s known for a locking tab that ensures a secure connection.

LC (Lucent Connector):

A smaller version of the SC with a similar push-pull style, but more compact. It’s commonly used in high-density applications.

ST (Straight Tip):

Utilizes a bayonet-style twist-lock mechanism. It’s commonly used in multimode networks, such as campus and building backbones.

FC (Ferrule Connector or Fiber Channel):

Features a screwon mechanism and is known for its high precision and secure connection, often used in datacom and telecom applications.

MPO/MTP (Multi-fiber Push On/Multi-fiber Termination Push-on):

These are multi-fiber connectors that can accommodate a large number of fibers (up to 12 or more), ideal for high-density applications like data centers.

MT-RJ (Mechanical Transfer-Registered Jack):

A small form factor connector that houses two fibers and integrates easily with existing RJ-45 copper plug designs.

MU (Miniature Unit):

Similar to the SC connector but half the size, used in high-density applications where space is a constraint.

DIN Connector:

Circular with 3-14 pins and a 13.2 mm diameter, it’s mainly used in older audio, video, and computer interfaces, like PC keyboards and MIDI instruments.

E2000 Connector:

Features a push-pull mechanism with an automatic metal shutter for dust and laser protection, making it suitable for high safety and high-power fiber optic applications.

Simplex vs Duplex Fiber Connectors

Simplex and duplex fiber optic connectors differ in signal direction and fiber count.Both simplex and duplex configurations can be used with various types of fiber optic connectors (like SC, LC, ST, etc.), with the choice depending on the specific requirements of the network or communication system.

Simplex Connectors:

Use one fiber strand for one-way signal transmission, meaning signals can travel only from device A to device B, but not back.

Duplex Connectors:

Employ two fiber strands for two-way communication, allowing signals to go back and forth between devices A and B.

3

Boot Length of the fiber optic connector:
Standard Boot vs Short Boot Connectors

Boot length in fiber optic connectors comes in two types, standard and short:

Standard Boot Connectors:

Have a longer boot for added protection, suitable for general use where space isn’t limited.

Short Boot Connectors:

Feature a shorter boot, ideal for tight spaces as they allow easier cable routing and maintenance without compromising performance.

4

Polishment: APC/PC/UPC Fiber Optic Connectors

Fiber optic connectors are categorized into PC, UPC, and APC based on their polishing styles, each with a unique color code and performance characteristics:

PC (Physical Contact) Connectors:

Black in color, they have a slightly curved end face for a decent connection quality with low insertion and return loss.

UPC (Ultra Physical Contact) Connectors:

Typically blue, these connectors feature a finer polish than PC, offering better signal clarity with lower signal loss.

APC (Angled Physical Contact) Connectors:

Green in color, they have an end face polished at an 8-degree angle, resulting in the lowest back reflection and superior performance in high bandwidth applications.

0.9mm, 2.0mm, and 3.0mm in the context of fiber optic connectors

The 0.9mm, 2.0mm, and 3.0mm sizes in fiber optic connectors refer to the compatible cable diameters:

0.9mm Connectors:

For thin 0.9mm cables, often used in tight spaces and internal device connections.

2.0mm Connectors:

Suitable for 2.0mm cables, balancing robustness and size for versatile indoor and outdoor use.

3.0mm Connectors:

Designed for thicker 3.0mm cables, ideal for harsh environments or where extra cable protection is needed.

Types of optic fast connectors

Optic fast connectors, designed for quick and easy field installations of fiber optic cables, come in various types, each with unique features catering to different requirements. Here are main typical types:

Optic Hot-Melt Fast Connector:

Uses pre-applied adhesive activated by heat. It’s ideal for strong, reliable connections with minimal insertion loss, suitable for onsite termination and field repairs.

Optic Fast Connector (Quick/No-Polish Connector):

A mechanical splice connector that doesnʼt require epoxy or polishing. It’s easy to install, making it popular for timesensitive applications and immediate service restorations.

Straight-through Fast Connector:

Designed for the fiber to pass straight through, using a mechanical splice for easy and quick field termination, suitable for repairs or temporary setups.

Pre-embedded Optic Fast Connector:

Features a factoryinstalled, pre-polished fiber stub, enabling quick, highquality connections with consistent performance, ideal for reliable and efficient installations.

How to select the right fiber optic connector?

Selecting the right fiber optic connector involves considering several key factors to ensure compatibility and optimal performance in your specific application. Here are the primary considerations:

Fiber Type:

Choose connectors compatible with your singlemode or multimode fiber, and the cable diameter (e.g., 0.9mm, 2.0mm, 3.0mm).

Polishing Type:

Select APC, PC, or UPC based on required back reflection and signal quality.

Connector Interface:

Decide among SC, LC, ST, FC, etc., based on your network’s design and equipment compatibility.

Simplex vs Duplex:

Decide among Simplex or Duplex based on the specific requirements of the network or communication system

Boot Type (Standard or Short Boot):

Decide based on space constraints. Short boots are useful in tight spaces.
