The Prysmian ESDF4 In Line Joint is an underground cable joint suitable for direct burial and underground chamber applications. The fibre splices/joints, manufactured by Prysmian, are used for the jointing, splicing and branching of optical cables with a total capacity of 72 fibres.

The Prysmian joint kit is supplied with six splice trays each able to accommodate up to 12 fibre splices. Cable entry glands, splice protectors and mounting brackets are ordered separately to suit the application requirements.

Note: Four Cable Entry Kits must be ordered per joint. If only two cables are required blank entry kits must be used to seal the fibre splicde or joint.
