Versatile and easy-to-use fiber closures for FTTH networks

Charles fiber optic round closures (FORC) provide a versatile and functional cost-effective solution for FTTH network connections. These compact closures are a space saving solution. They have a feed port and two branch ports. The units are an ideal solution for a repair closure. In addition, the branch ports can be fitted with multi-cable grommets to splice in drops and can be used as a drop closure. These closures are fully sealed units which can be installed to meet any deployment requirement.
