Choosing the right multi-channel connector

Selecting the appropriate multi-channel fiber connector for your application is crucial to ensure optimal performance, reliability, and ease of maintenance. Multi-channel fiber connectors are connectors that allow multiple optical fibers to be terminated in a single connector, facilitating high-density connections and efficient data transmission. Here, we'll explore some commonly used multi-channel fiber connectors to help you make an informed decision.

Expanded Beam Connectors - are different from traditional connectors, instead of the fibers physically touching when mated, the light is beamed through optical lenses. This technology gives advantages when it comes to durability, reliability, susceptibility to contamination, and ease of maintenance. MIL-DTL-83526 optical performance.
- Easy maintenance and cleaning
- Less susceptible to contamination
- Less susceptible to misalignment

MIL-DTL-38999 - are widely used in military and aerospace applications for optical transmission due to their high performance and reliability in harsh environments. These connectors offer a compact circular package and are available in various different shell sizes, materials, and finishes. It can be configured using MIL-PRF-29504 pin and socket that fits the standard size 16 copper contact inserts.
- Self-locking vibration resistance
- Threaded circular connector
- Variety of interface configurations

ARINC 801 - is a standard for fiber optic connectors used primarily in aerospace and military applications. These connectors are designed to provide high performance and reliability in harsh environments. Genderless terminus design with removable alignment inserts using ceramic alignment sleeves and ferrules to ensure accurate fiber alignment results in reliable connections and ease of maintenance. Rotation-locked termini enable APC interfaces for improved return loss performance.
- Available in UPC or APC end-face
- Genderless terminus design
- Removable alignment sleeve insert
