Fibre Optic Expanded Beam Connectors, WBT15

In stock
Stock Code

The WBT15 connectors, featuring expanded beam technology, hermaphroditic connection, rugged construction for field deployment and hybrid configurations, have been designed for harsh environment applications such as military tactical communications, avionics, offshore systems, outside broadcast, mining and plant.

The expanded beam technology uses expanded and collimated beams to couple optical fibres without any contact. It could allow for optics to be used in areas that have been quite restrictive due to the presence of damage or contamination at the fibre end. Hermaphroditic connector design enables fast deployment by daisy-chaining multiple cable segments. WBT15 connectors also enable the transfer of electrical signal or power using hybrid insert configuration.
