256 Cores Fiber Splice Enclosure 4 Ports

MBN-FOSC-A2 256 Cores Fiber Splice Enclosure 4 Ports is a universal access junction box that allows the continuity and segregation of medium capacity optical cables used in the deployment of optical power networks and transport. The design of the box allows the mechanical continuity of the cable pulling elements and protects the fibers,  the junctions and optical devices facilitating the organization of splices and fiber surplus storage. The box is airtight and resistant to weather conditions by which can be installed both outdoors and indoors buildings in chambers of record, boxes, walls, posts or cable galleries.

Features:
1.It has 4 independent cable accesses at one end. Each of them allows individualized entry into the less two medium-capacity multifiber cables (double inputs) and up to 6 small capacity optical cables (7mm.).
2.The closing cover is completely assembled and removed without the need for special tools thanks to the clip-type seal.
3.The sealing of access cables to the box is done by rubber gaskets with pre-cut entries.
4.Diameter inputs/outputs cables from 22 to 7 mm. Maximum 256 fusions of F.O (double layer).
5.Wide and easily accessible rectangular splice trays with extendable tabs for better fiber storage up to 32 F.O. (double layer). Both the support block and the individual trays allow 90º turn and its interlocking in fixed positions to facilitate installation.
6.The boxes can be opened, closed, and manipulated without interrupting the circuits in operation. It allows joining and segregating cables without having to cut all the fibers as well as the proper storage of the tubes and / or leftover fibers of the cables. 
7.Axial tension Cable load> D / 45 mm x 1000 N. D: cable diameter. 1 hour per cable. Cable offset <3 mm
8.Cable flex: 30 ° max. 500 N. Application of force: 400 mm from the end of the seal. No. of cycles: 5 / cable.
9.Cable twist: Maximum rotation torque 90 ° / max 50 N. Force application: 400 mm from the end of the seal. No. of cycles: 5 / cable.
10.Vibration Frequency: 10 to 15Hz. Speed: one octave per minute. Cycle: sinusoidal; amplitude: 3 mm (6 mm crest to crest). Cable clamp: 500 mm from the end of the seal. Duration: 2 hours per axis Static load> 1000 N (25 cm2, 10min).
11.Operating temperature -25 to +70 oC.
12.Degree of protection against mechanical impacts IK09 (20 J).
13.The box once closed is completely hermetic and resistant to weather conditions. Degree of protection IP-68.
14.The materials are designed for a minimum duration of 20 years.
