A fiber termination box is the enclosure where the field cable ends inside the building, fibers are spliced to pigtails and access is provided through adapters. Rack-mount patch panels, wall-mount boxes and DIN rail boxes perform the same function in different mounting scenarios.
Three areas are planned together at a termination point: the front face holding the adapters, the splice tray storing the joints and the rear section where the field cable enters. Tray capacity limits fiber count; a 24-fiber cable cannot be terminated in a 12-position tray. The rear section holds the clamp securing the cable jacket and the area where slack fiber is coiled within its bend radius.
Rack-mount panels come in 1U and 2U heights. Blank panels are configured with adapter plates, so one panel can serve different connector types and be populated in stages. Loaded panels arrive with adapters fitted and shorten installation time. On density, 1U yields 24 ports with LC duplex adapters and roughly 12 with SC duplex.
Wall-mount boxes serve floor distribution points, small offices and areas without racks. A lockable cover prevents unauthorised access and dust ingress. In industrial settings, DIN rail boxes are mounted inside enclosures. Whichever type is chosen, labelling space matters: without a record of which port serves which link, every later intervention requires measurement.
