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 MILSTD-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.
DURABLE
• No wear on the optical interface
• Shock and vibration resistant
• Highly resistant to dirt and debris
REPEATABLE, LOW-LOSS
PERFORMANCE
• Low sensitivity to thermal
fluctuations and interface
contamination
