Rugged Single Mode and Multimode Optical

Performance for Harsh Environments

Leveraging our industry accepted PRO BEAM Expanded Beam technology, TE

Connectivity (TE) has developed its newest rugged expanded beam optical termini —

Single Mode (SM) and Multimode (MM) EB16. The EB16 termini are size 16 optical

contacts, fit-form compliant with MIL-DTL-38999 Series I and Series III and MIL-

STD-1760 lanyard release size 16 AWG cavity. These termini are drop-in replacements for

the MIL-PRF-29504 /4 and /5 physical contact termini used in many ruggedized circular

connector systems and can also be used in a hybrid combination with power contacts.

Non-Contacting Interface

Contrary to the physical contact 29504 termini, the springless EB16 does not

require mating by a spring force. This feature is particularly useful in reducing the

substantial mating force required when using high-count connector inserts. The

expanded beam optical, non-contacting interface prevents wear and tear on the light

carrying elements of the termini, especially in high-mating cycle, high-vibration

and/or high shock applications.

The ball lenses of the pin and socket termini expand and collimate the optical signal

into a beam size well beyond its original size to provide easier optical alignment, low

sensitivity to contamination and consistent performance over thermal changes. The

beam traverses the interface airgap from the transmission side and is then refocused

back into the core of the receiving fiber.

The beam area is expanded approximately 150 times between lenses with limited

signal deterioration by airborne contamination particles of the same size that affect

the performance of the PC connection. The termini’s end-face is easily cleaned.
