The 4 cores Wall Mount Metal Fiber Terminal Box is a compact metal fiber optic termination box (FTB/OTB) designed for small-capacity optical distribution, pigtail fusion splicing, and cable patching. Fabricated from premium cold-rolled steel sheet with an electrostatic spray-coated finish, this indoor enclosure delivers superior mechanical strength, corrosion resistance, and physical protection for optical fibers.
Serving as a compact demarcation and distribution point, the unit securely anchors incoming distribution cables, provides dedicated routing tracks for bare fibers, and enables direct cross-connection to subscriber drop lines via front-access adapter ports.
