ODF distribution frame 48-core Rack Mount 4U type with SC/UPC Adapter

An optical distribution frame (ODF) is a frame used to provide cable interconnections between communication facilities, which can integrate fiber splicing, fiber termination, fiber optic adapters & connectors and cable connections together in a single unit. The basic requirement is ODF should allow for easy access to the connectors on the front and rear of those ports for insertion and removal. It is usually used as the interface between optical transmission network, optical transmission facility and between optical cables in access network of optical fiber subscribers. It can also work as a protective device to protect fiber optic connections from damage.

Wolonte 19" ODF offers flexible cabling access, expandable frame design and comprehensive cable management. A series of optical distribution frames of 12 fibers, 24 fibers, 48 fibers, 72 fibers and 96 fibers counts type are available.

Generally, the ODF unit box is a necessary part of the indoor optical distribution frame. 12 cores fusion splicing and distribution module plays the main role and its function is splicing, fiber storage and protection. A completed ODF unit will be with adapter, pigtail and accessories like splice protection sleeve, nylon tie, snake like tube, screw.
