    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.
