HD1.25mm optical termination method

Tyco Electronics has developed the HD1.25mm optical termination method (terminus) for aerospace and defense applications where a common terminus for all types of connections is required.

The HD1.25mm is a physical contact method of connecting high-density, low-cost fiber-optic connectors. It can be used in a number of connector shell styles including the size 8 quadrax cavity reducer, ARINC 600, LC adaptor, MIL-C-38999 and general-purpose rectangular types. The mean insertion loss (method B) is 0.10dB for single-mode and 0.07dB for multi-mode applications.

The HD1.25mm termini combine a simple, robust and compact design that compares well with traditional MIL-T-29504 termini, said the company. For example, this terminus can be used for all connectors whereas other methods may require several terminus designs which typically increase complexity and cost.

In addition, the HD1.25mm termini use a pull-resistant design that does not require a strain relief on the backshell which simplifies assembly. They also use a genderless contact, which allow the use of the same contact on both connector halves. This also enhances the product's simplicity and ease of use, said the company.

Compatibility with multi-mode and single-mode fibers makes the HD1.25mm termini useful in a wider range of applications as compared to other methods. In addition, standard 1.25mm ferrules and sleeves along with LC-type connector polishing add to ease of installation.

HD1.25mm termini kits are priced at $5 to $10, depending on quantity. Delivery is from stock to six weeks.
