Amphenol Fiber Systems International M29504 Fiber Optic Connectors

Amphenol Fiber Systems International (FSI) M29504 Fiber Optic Connectors operate in a -65°C to +150°C temperature range, making them ideal for fiber optic interconnections in harsh environments. These cost-effective, high-precision connectors are designed to fit into MIL-DTL-38999 Series III, pin size 16 connectors and are available for single-mode and multi-mode applications. The series conforms to the rigorous conditions of the MIL-PRF-29504D specification. Amphenol FSI M29504 Fiber Optic Connectors are optimized for low insertion loss, low back reflection, and durability. All ferrules are available in standard or ultra-polished end-faces for tight optical budget applications. The pre-domed design feature minimizes epoxy removal and polishing times.
