ITT launches new fiber optic interconnect for harsh environments

by K C Krishnadas, TechOnline India - February 21, 2012

Ideal for defense and aerospace applications, the high-density PHD38999 connectors and terminations are qualified to the industry-standard M38999 specification.

ITT Interconnect Solutions, a manufacturer and supplier of connectors, interconnects and cable assemblies, has developed a fiber-optic interconnect solution for harsh environment applications. Using a tunable size 22 fiber-optic termination system, the PHD38999 Series interconnect is qualified to the industry-standard M38999 specification, making it suitable for use in demanding defense and aerospace applications, including vision systems, flight connectors and control systems.

The PHD38999 Series connector, with its size 22 termination system, has completed Design Verification Testing (DVT), including meeting stringent specifications for mating repeatability, temperature cycling, vibration, mechanical shock, humidity and mating durability.  It offers high density of up to 50 channels per square inch and features removable sleeve inserts that allow direct end-face access for termination cleaning and inspection. The PHD Series’ termination retention is achieved via ITT’s patented Little Caesar contact retention clip technology, which provides unparalleled flexibility for installing, servicing, cleaning and repairing a single optical channel.

DVT results for the size 22 PHD38999 terminations showed less than 0.20dB Change in Transmittance (CIT) after five hundred mating and de-mating cycles. The temperature cycling test was performed between extremes of -55°C and +105°C, with the connector being held at these extreme temperatures for an hour.
