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.

|Operating wavelength||C band: 1528-1563 nm, L band: 1570-1605 nm, 1310 band: 1295-1325 nm, 1480 band: 1465-1495 nm|
|Return loss/directivity||55 dB ¹|
|Pigtail tensile load||5 N ²|
|Optical power handling||4 W|
|Environmental qualification||Component design to 0.1FIT Failures in 10⁹ hours|
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. Guaranteed by design.
² Stripped fiber proof tested on rig to confirm strength.
