Features and Benefits
- Operates optimally with low modal dispersion at both 850 & 1300 nm
- Radiation resistant
- Available with dual, hermetic-carbon & either PYROCOAT or high-temperature silicon coatings
- Available with tight tolerance on coating diameter to meet stringent military applications
Typical Applications
- Aircraft communications
- Military and space applications
The FLIGHTGUIDE family of aerospace cables provides high temperature and strength capabilities for a range of fiber types including Singlemode, 62.5 u and 100u core graded-index fibers. Proven success with 100/140u fiber based cable on F-22 aircraft and Comanche helicopters has been extended to meet the growing requirements for Singlemode and 62.5u fibers in stringent military and commercial environments.
For each of these base line fiber types, hermetic and PYROCOAT coating options are available. All fibers utilize the standard silicone/Tsfzel upbuffer configuration.
The Premium FLIGHTGUIDE configuration proven on F-22 aircraft has a guaranteed minimum bandwidth of 200 MHz-km at operating windows of both 850nm and 1300nm, and the PYROCOAT coating diameter has a high tolerance of +/- 1u. The higher bandwidth of the premium grade of FLIGHTGUIDE allows for the higher rate of transmission required for applications such as target acquisition, navigational system starus and high speed communications to and from mission computers. The special cable design of FLIGHTGUIDE allows for fiber optic harnesses to be deployed throughout an airframe without degradation to the optical signal.
