    Mr Pablo
    I was surprised when i made first order with Kocent Optec Limited in 2014. One container 40GP of GYXTW cable and one container 20GP for fast connector, patch cord and adapter. They finished this order in 2 weeks only. Now we also purchase many type of FDB box and Splice Closure Box from them. Hope we will be stronger and stronger in telecom field.

Product Description
D4 Fiber Optic Connectors Duplex for SM MM Optic Fiber Patch Jumpers
D4 fiber optic connectors provide reliable duplex connectivity for both single-mode and multimode fiber optic patch jumpers, engineered for precision performance in demanding network environments.
Connector Design & Construction
The D4 fiber optic connectors feature a 2.0 mm ceramic ferrule that securely holds a single fiber. While similar in design to FC connectors, D4 connectors incorporate a smaller ferrule and extended coupling nut for enhanced performance. These connectors deliver comparable properties and applications to FC connectors while offering superior precision alignment.
