This 62.5 µm multimode graded-index fibre optic cable is an aerospace-grade solution tailored for in-flight connectivity and avionics networks. Engineered as a compact 1.8 mm simplex cable, it is ideal for use in aircraft data systems such as in-flight entertainment, internet access, and cockpit display networks. Its ruggedised single-jacket construction is designed to withstand vibration, bending, and challenging aircraft operating conditions.
The cable is intended to meet or exceed ARINC 802 requirements for tight-buffered fibre cables in commercial aircraft. A bend-optimised optical design helps preserve signal integrity through constrained routing paths. The lightweight construction supports efficient installation where space and weight are critical. With strong mechanical durability, broad chemical resistance, and aerospace-focused performance, it is well suited for reliable optical links in commercial and defence aviation environments.
The FlightLinx® 62.5/125 µm multimode fibre cable is built for aircraft networking environments where reliability, compact routing, and low weight matter. As a rugged 1.8 mm simplex aerospace fibre optic cable, it supports applications such as in-flight entertainment, Ethernet access, display systems, and avionics data links.
Its construction combines a graded-index multimode optical core with protective buffering, reinforcement for pull resistance, and a fluoropolymer outer jacket for durability in harsh aerospace conditions. The result is a dependable fibre solution for commercial aircraft installations that demand performance, safety, and long-term mechanical stability.

FAQs
for FlightLinx® Simplex 1.8 mm Ruggedised Cable 62.5 µm Multi-mode Graded-Index
This is a multimode fibre optic cable using a 62.5/125 µm graded-index core. It is intended for multimode transmission, typically at 850 nm and 1300 nm wavelengths, in aerospace networking and data applications.
The cable is specified with attenuation of ≤ 4.0 dB/km at 850 nm and ≤ 2.0 dB/km at 1300 nm. It provides bandwidth of ≥ 160 MHz·km at 850 nm and ≥ 500 MHz·km at 1300 nm, making it suitable for aircraft data and video links over typical onboard distances.
The cable is presented as meeting or exceeding ARINC 802 requirements for commercial aircraft fibre cabling. It is also described as meeting FAR 25.869 flammability criteria, supporting use in aircraft environments where fire safety and low smoke behavior are important.
Yes. It is designed as a rugged aerospace cable for installation in aircraft systems where vibration, constrained routing, and exposure to harsh conditions can occur. The construction is intended to support dependable performance in demanding aviation applications.
The cable includes aramid fibre reinforcement for mechanical strength. It is rated for a maximum installation tensile load of 86 N (19.3 lb) and a maximum operating tensile load of 43 N (9.7 lb), helping protect the fibre during deployment and service.
The recommended minimum bend radius is 25 mm during installation and 8 mm during operation. This supports routing through tight aircraft spaces while helping preserve signal quality and cable integrity.
Because the cable uses a tight-buffered simplex construction, it is suitable for termination with standard aerospace fibre optic connector systems designed for this cable style. This can help simplify integration into avionics and aircraft network assemblies.
Yes. The outer jacket is described as PFA fluoropolymer, which offers strong resistance to aviation fluids, oils, hydraulic chemicals, and cleaning agents. This makes the cable suitable for environments where incidental chemical exposure may occur.
Yes. The wider FlightLinx product family is described as including additional multimode and single-mode variants, allowing selection based on bandwidth, distance, and system performance requirements while maintaining a rugged aerospace-oriented design approach.
