The reference is different. Optical fiber distribution frame: optical fiber distribution equipment specially designed for optical fiber communication equipment room. ODF distribution frame: It is an important part of the information room, with optical cable fixed protection, optical cable connection and line adjustment functions.
ODF distribution frame: It is an important part of the information room, with optical cable fixed protection, optical cable connection and line adjustment functions. 2. Use differently. ODF distribution frame: It can protect the core and pigtail of the optical cable.
This ODF would normally be associated with the optical fibre cable first installed at the site. Equipment installed later (on the same or nearby equipment racks) required to operate over fibres in the same cable, would be connected to these fibres via optical patch cords running from the ODF to the new equipment.
