ARINC 801

The ARINC 801 fiber optic terminus is the next generation of high density, butt joint interconnect technology. With its standard 1.25 mm ferrule and sleeve, the ARINC 801 terminus is designed for both multimode and single-mode applications. For the pull-proof design, the cable jacket is crimped on an external body and a floating mechanism avoids any loss of performance when pulling on the cable. This feature allows for the use of the connector without a backshell. Standard connector formats include MIL-DTL-38999 type, MIL-DTL-83527 type, ARINC 600 and ARINC 781.

DIN Contacts

Rugged DIN style contacts and connectors that are capable of supporting wide bandwidth applications. All fiber optic contacts are offered fully terminated and tested to ensure integrity for rugged environments. Smiths Interconnect also offers a complete line of fiber optic connectors to terminate to the other end of the cables. These include ruggedized single channel (RSC), FC, ST, LC Duplex/Simplex, MTP, MT-RJ and Ruggedized SC connectors. Please consult factory for cabling options.

Fibre Channel D-Sub
