Telecommunication Brass D4 Fiber Optic Small Form Factor Fiber Connectors
D4 connector is one of the older generation connectors which is keyed, and spring loaded. Connector body is nickel plated brass for enhanced durability. D4 fiber connectors are made from a 2.5mm diameter ceramic (zirconia) ferrule for durability. They have a high-performance threading mounting system and a keyed body for repeatability and intermateability. The Fiber Optic D4 Connector's threaded mounting system provides a strong, secure connection and is popular for telecommunications and datacom fiber optic applications.The design of the D4 Fiber Optic Connector is similar to that of the FC fiber optic connector, except that the D4 has a smaller ferrule and a longer coupling nut. In addition to D4 Fiber Optic Connectors, we can offer fiber optic small form factor and standard size connectors for all of your termination needs.
