Military cable assembly solutions

Military cable assemblies are specialized data & power cable systems designed and manufactured to meet the stringent requirements of the military and defense industries. These cable assemblies play a critical role in various military applications, including communication, data transfer, power distribution, and more.

  • Built to withstand harsh environmental conditions
  • Compatible with the latest military standards
  • Highly customizable

Fiber optic solutions

To guarantee flawless data transmissions through fibers, the process of cutting, stripping and assembling fiber optic components must be performed with the highest precision and requires dedicated tooling, techniques, procedures, and craftsmanship.


The precise alignment and positioning of the fibers, as well as their preparation and outgassing, are particularly challenging tasks, and a meticulous execution is needed to reach best optical performances. Furthermore, only correctly cleaned fiber strands can prevent bad fusion splices and inadequate bonds. Our optical solutions offer:

  • Optimal quality and stability of the optical link
  • Designs enduring rough use in extreme outdoor conditions
  • Easy use in the field

Single Pair Ethernet

The increasing density of sensors, actuators and controllers in networked devices used in industrial automation, transportation, smart cities and defense poses particular challenges in Ethernet connectivity, among which long cabling distances to cover, bandwidth limitations from legacy connectivity systems, and complexity from managing multiple protocols. These challenges have fueled the demand for a smaller, lighter and more affordable version of the Ethernet, the Single Pair Ethernet (SPE), which uses just one pair of twisted copper wires and offers:

  • Data transmission at speeds ranging from 10 Mbit/s to 10 Gbit/s
  • Power over Data Line (PoDL) up to 52 Watts
  • Over distances from 15 meters (at 10, 100 and 1,000 Mbit/s) to 1,000 meters (at 10 Mbit/s)

In leveraging our technologies dedicated to applications requiring faultless precision, durability and resistance to extreme conditions, we combine SPE’s unique features with our high-reliability, high-performance, sealed connectors to take SPE connectivity to new application dimensions in industrial production lines and defense UAVs.


Miniature & high-density cable assembly

Cabling miniature and dense connectors is extremely challenging and requires special technical know-how and specific tooling, assembly techniques and testing methods, well mastered by our operators. Miniaturization processes pertain to the entire chain of the cabling design and manufacture, including:

  • Part alignment on both the plug and receptacle
  • Bend relief cutting and cable jacket stripping
  • Conductor back trimming and stripping
  • Soldering, braid shielding, insulator tube and back nut potting
  • O-ring and boot bend relief fixation, etc.

Leverage our expertise in miniaturization to design compact, lightweight and small-footprint cable assemblies that fulfill the shape, size, weight and power (SWaP) requirement of your device and electronic ecosystem.


Silicone cable assembly solutions

Overmolds and heat-shrink tubing that provide sealing at the junction of the connector and the cable can impart functionality such as abrasion and impact resistance, low friction, vibration damping and protection from fluid ingress. One of the insulation materials available in rubber is silicone. It’s generally non-reactive, stable, resistant to extreme environments, and offers the widest thermal range (from -60 °C to 180 °C). Silicone cable assemblies thus stand up to any sterilization challenge you can throw at them: steam autoclave, high heat, disinfectants and sterilant solutions. Our wide range of silicone cable assemblies includes:

  • Custom silicone overmolds
  • Custom geometries
  • Low-friction coating to prevent damage over the lifetime of the cable
  • Custom colors available

The silicone overmolds from the Fischer Core Series in sizes 104 and 105 are medical cable assemblies tested to ISO 13485.


Optimized cabled solutions

No matter what stage of the design process you’re at, whether it be initial project sketches or fully defined design solutions, our experienced cable assembly engineers will work with you to help specify and select the proper materials and optimize the form, fit and function of a large variety of electrical, optical, fluid/gas and hybrid connections. Our engineers consider the end-use application and its environment and ecosystem as a whole, and integrate third-party connectors as well. Our capabilities include:

  • Overmolded cable assemblies for bend protection (thermoplastic and silicone) and right-angled overmolds
  • Wiring harness assemblies
  • Internal potting enhancing sealing level to allow for submersion
  • Heat shrinking for added protection and support to exposed wire
  • Breakouts, pigtails, fiber optic termination
  • Low cost and disposable options, etc.

Our solutions are compliant with the highest technology standards in terms of ruggedness, sealing and high-speed data transmission.


Rugged cable assembly solutions

Connectors and cables must be assembled and optimized through specific tools, techniques and materials for your rugged device to function properly, reliably and durably in severe operating conditions and harsh environments. Rely on our engineers and operators’ designs, materials and technologies to ruggedize your cable assembly solution so as to make it withstand weathering, abrasion, shocks, vibrations, temperature extremes, electromagnetic interferences, radiations, chemicals, as well as sterilization and cleaning processes.

  • High sealing performance
  • EMI shielding
  • Flex life
  • Resistance to tension force

The ruggedization processes we master comply with the highest connectivity standards.

Custom overmolds and cable colors are also available, e.g. tan 499 for defense applications.
