In demanding environments, completely different requirements are imposed on fiber connectors and cables than ordinary equipment can supply. Foss has several series with robust contacts and makes Plug & Play solutions designed for our customer’s needs. 

Key features are resistance to water and dust, ability to operate in a wide temperature range, possibility to lock of connected contacts and, not least, that they can withstand substantially greater physical stresses. 

We build complete Plug & Play solutions for demanding conditions in defense, offshore and industrial environments, based on high-quality fiber optic cables and connectors. The advantages for such factory-configured solutions is that the work is carried out in a controlled environment by trained technicians, and that the products are carefully tested before they are dispatched to our customers.

4-fibre PBJR plug-PBJR plug, 50/OM2

Multimode OM2 tactical cable with 4 channel ProBeam Jr. plugs in each end. Probeam connectors are hermaphroditic so cables can be daisy chained.

8-fibre PBSR plug-PBSR plug, 9/OS2, PUR

Singelmode tactical cable with 8 channel ProBeam Sr. plugs in each end. Probeam connectors are hermaphroditic so cables can be daisy chained.

Reel, 250 m, green

Tactical reel in aluminum with capacity for around 250 m ProBeam tactical cable.



The ProBeam connector is an extreme robust connector. It can be used by anyone, almost anywhere. The plugs are water tight and can be used by unskilled personnel. In ProBeam, the light beam from the fiber is broadened in a ball lens to a diameter that is substantially larger than in a normal contact. This technique is often referred to as Expanded Beam Technology. This makes them much less sensitive to dirt, while cleaning the contacts can be done without special equipment. ProBeam comes in two sizes that deliver up to 4 or 8 fibers. The system is designed and certified for military purposes, but is used in a number of contexts where impurities are a problem. The special lens contacts spread out the light over an area that is many times as large as traditional contacts. This makes them much less sensitive to dirt, while cleaning the contacts can be done without special equipment. Our ProBeams are terminated on OCC tactical cables and are often supplied on our cable reels.

Cable reels

Our field drums are designed for handling fiber cables in temporary installations. The drums are lightweight, combined with high strength and manufactured in painted aluminum. They come in three sizes with capacity for 100, 250 or 500 meters of cable. All sizes have double flange for easy access to the inner-end and protected space for storing the contacts. The drums have brakes, fold-in swivel handles, and drums of the same size can be stacked in height. As standard, the drums are painted in military green RAL 6014, other colors available on demand.


The IP-series is based on standard LC or MPO connectors. The connector housing ensures mechanical protection while at the same time protecting against exposed weather conditions. These connectors are normally used in temporary connections. Typical applications is in antenna towers or between containers. The IP-series delivers LC and MPO connectors in a protective IP68 housing. The IP-series is ODVA compatible. The IP-series delivers LC connectors or MPOs in a protective housing that provides an protection against dust and water certified at IP68. IP-LC has 2 fibers, while IP-MPO has 12 or 24 fibers.

Harting HAN

The Harting Han is a robust fiber connector for industrial environments. It enables temporary connections with up to 24 fibers in one connector. A typical system consists of a cable with plugs at both ends. The ends are connected to the chassis connector which has the transition to standard fiber connectors. HARTING Han comes in different versions, based on the environment in which they are to be used. Harting HAN can be mounted on a long line of cables, but is mostly used with the industrial cables AICI and QFCI. They can also be combined with copper and fiber in the same contact. Hybrid versions that combines fiber and copper are also available.

Hawke series

The Hawke connector combines the strength of market leading connection range with the latest in Ex Fiber Optic specifications. It is designed to meet the latest BS EN 60079- 28:2015 standard for protection of equipment using fibre optics in explosive atmospheres. The FibreEx offers an easy-to-install solution that will keep the network running, even in the world’s most arduous environments. Hawke series are nickel plated connectors for use in explosive atmosphere (ATEX) according to EN 60079-28:2005. The Hawke connector may be delivered as connector plug, connector receptacle or bulkhead receptacle. Both single mode and multi mode is available. A protective cover is included on all variants.
