HIGH RELIABILITY 1480/1550 NM WDM

Fused Fiber WDM

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 programs, which can consist of accelerated ageing and Weibull analysis.

Manufacturing is carried out on specially-developed workstations. Advanced fiber management, in-process screening and customer-specific validation tests are implemented, to further enhance component reliability.

Component types available include fused fiber couplers, tap couplers and wavelength division multiplexers. The ultra-low loss of G&H fused fiber components helps to promote low noise figure and improved system margin in undersea transmission systems.

Components are supplied in regular (bare fiber) or custom housings, depending on the installation environment.

Please contact us to discuss your specific requirements.

1 Insertion loss over operating wavelength range and component life – not including PDL, TDL (25 years, typical service/storage conditions 40°C/60% RH).

2 Change in insertion loss over the operating wavelength range. 

3 Change in insertion loss over all input polarisation states in signal wavelength range. 

4 Change in insertion loss on signal path from -5 – 75ºC. Guaranteed by design.

5 Center wavelength tolerance for repeatability in system ±2 nm.

1 Return loss is the ratio of power launched to power reflected for port P1. Directivity for the 2x2 component is the ratio of power launched to P1 to the power reflected to P4. For 2x2 couplers return loss/directivity >60 dB and is guaranteed by design.

2 Stripped fiber proof tested on rig to confirm strength.
