Fused Fiber Optic Components

Passive optical components are widely used for branching optical signals as well as interfacing with the outside world. Components manufactured from single mode optical fiber are often used in telecommunications systems, sensor systems and biomedical systems. Multimode components are often used in high power fiber laser systems.

2000nm (2um) Components

The 2um region of the spectrum is becoming increasingly important for sensing and fibre laser applications. In particular, 2um fibre laser technology has the potential to open a whole new area of industrial micromachining applications such as marking glass and plastics, as well as other materials which are transparent in the 1um spectral region. G&H’s 2um components are manufactured on the same platform as our existing components ensuring high reliability and high optical specifications as standard.

High Reliability Couplers (HI REL)

High Reliability (hi-rel) Components are deployed in environments such as undersea and space where the costs of component replacement are prohibitive. Gooch & Housego is established as a supplier of these components to major undersea equipment manufacturers. G&H’s hi-rel capability is built upon the foundation of a long established history of manufacturing very reliable terrestrial components. Full facilities are available to carry out customer-specific hi-rel qualification programmes which can include accelerated ageing and Weibull analysis. Manufacturing is carried out on specially-developed workstations. Advanced fibre management, in-process screening and customer-specific validation tests are implemented to further enhance component reliability. Component types available include fused fibre couplers, tap couplers and wavelength division multiplexers. The ultra-low loss of G&H fused fibre components helps to promote low noise figure and improved system margin in undersea transmission systems. Components are supplied in regular (bare fibre), semi-ruggedised (0.9mm sleeving) or custom housings, depending on the installation environment.
