Using our proven fused biconical taper process, our HI REL capability is built upon the foundation of the long-established manufacturing history of very reliable terrestrial components.
The ultra-low loss of our fused fiber components helps to promote low noise and improved system margin in undersea transmission systems.
Full facilities are available to perform customer-specific HI REL qualification programs, which can consist of accelerated aging and Weibull analysis. Our design standard is 0.1 FITs, meaning failure-free operation for one billion field hours.
Manufacturing is carried out on specially-developed workstations, and advanced fiber management, in-process screening, and customer-specific validation tests are implemented, to further enhance component reliability. Components are supplied in regular or custom housings, depending upon the installation environment.

¹ All specifications are for operation on slow axis at center wavelength (975 and 1545nm), room temperature, SOL (start of life) and no guard banding.
² CH1 wavelength range is below the 2ⁿᵈ order mode cut-off for the fiber used to manufacture this product type. Performance specified for single-mode incident on this path.
³ Custom specifications available on request.
⁴ 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. Guaranteed by design.
⁵ For operation at powers of greater than 4 W the component housing and fiber must be adequately heat-sunk (for additional information contact G&H sales). Components intended for high power operation are only available in the 2x2 configuration. Component performance and reliability under high power must be determined within the customer system.
⁶ Fiber and taper proof tested during build to confirm strength.
