Description

576 Core Fiber Optic Cross Connect Cabinet,Max.Suitable for 16 PCS Box Type Splitter,Installation Ways:Floor Installation or Wall-Mounted is optional,Size:1450mmx760mmx540mm,Material:Material Stainless Steel.


General

This series optical cross-connection cabinet is mainly made up of Stainless Steel or SMC case, fixing elements of the case frame, cable fixing and protective device, direct welding module, terminal module integrating welding and distributing, wiring duct and tail optical fiber coiling device. The distribution box is suitable for the connection, distribution and dispatching of outdoor link fiber cable and optical distribution cable. Besides.


Features 

Large capacity: the maximum distribution capacity is 96-cores, 144-cores, 288-cores, and 576-cores four types of optical fiber cables, and the capacity of direct welding is single, 120-cores -240-cores, and 240-cores -480-cores ribbon optical fiber cables.

The cabinet adopts special high-strength corrosion-resistant materials, has good waterproof, anti-condensing, moisture resistance properties, and can stand various adverse effects caused by climate and environment.

The cabinet is equipped with horizontal wiring duct, and makes the optical cable layout more reasonable and tidy.

Adopts the terminal tray integrating welding and distributing. Welding and distributing are performed at the same level, which makes the operation convenient, reduces the length of ribbon tail fiber and lowers the cost.

The terminal module adopts the horizontal draw-out structure with 12 cores as a unit, each core can be drawn out separately, which makes it convenient to operate in distributing, and reduces the number of bends arising from the distributing of tail fiber.

The optical fiber splitter is structurally reasonable, the optical fiber cable core is sheathed with sleeve, and the fixing, grounding and other operation on optical fiber cable can be performed, without removing the optical fiber splitter.

Method of Operation

1. Unlocking method: (see the map below)

(1) Insert the key, rotate 90 degrees, press down “PUSH” button, and make the handle pop up outwards.

(2) Hold the handle to rotate it to the bottom counterclockwise, hold the handle and open the door.

(3) Close the box door, hold the handle to rotate it clockwise to the vertical position, press down the handle inwards and reset it; then rotate the key 90 degrees and lock the door. (Warning: if the door is opened not in this unlocking method, it is forbidden to pull out the handle by force).

      

2. Cable entering method:

③ Upper layer of welding-distributing board   ④ Reserve excess length

Binding position of optical fiber cable

(1) Remove the plastics at the bottom plate threading of the case bottom. Strip the cable at the position 50mm away from the bottom plate and the stripping length shall not be less than 3m.

(2) After the cable enters the box, bind up the cable and fix it on the fixing plate of cable; meanwhile, fix the strength member, penetrate the fiber core protective sleeve, and insert it into the duct of fiber splitter head.

(3) After the optical fiber that is sheathed with sleeve goes through the horizontal wiring duct, traverse the hole on the right side of bottom plate, tie it up with strapping tape in appropriate poison of the right plate; finally, the optical fiber reserves the excess length, and fixes the cable with the strapping tape at the entrance of cable of upper layer of tray. See Figure 5.

(4) After all cables enter the box, seal it with greases in the position of cable entering of bottom plate.

3. Tail fiber arrangement and optical fiber welding

(1) Pull out the composite tray outwards, and open the cover plate.

(2) Lead the optical fiber cable core (about 1m to 1.5m) to the composite tray, coil the excess fiber on the upper layer of composite tray, strip off the cable optical fiber core wire sheath at the head, clean the exposed fiber, and lead it to the welding block.)

Fix the splitter of ribbon tail fiber or bundle tail fiber at the lower layer of composite tray, as shown in Figure 7, coil the surplus tail fiber on then end of connector on the composite tray of lower layer, clean the connecter head, and fix it on the adapter, as shown in Figure 6. Twist the ribbon or bundle part from bottom to upper layer, coil the surplus tail fiber and lead it to the welding block.

 

Figure 6 Wiring diagram (ribbon tail fiber 12 cores)

If it is single-core tail fiber, first clean its connecter and connect it with the adapter; coil the surplus tail fiber on the lower composite tray, go through the upper tray, remove the yellow sheath of tail fiber, and lead the tail fiber into the welding block, as shown in Figure 7.  

 

Figure 7 Wiring diagram (sing tail core 12 cores)

(3) Cover the core wire with the heat shrinkage bush at the welding blocking, weld it with the tail fiber, slide the heat shrinkage bush to the welding point, heat it to make it shrink, and finally insert it into the duct of welding block.

(4) Recover the upper and lower tray of composite trays, cover the aluminum alloy cover plate, and push the composite tray into the guide rail of composite tray.

(5) Clean both ends of jumper wire, fix one end with the adapter of composite tray, through the fiber protection circle and vertical wiring duct, coil the surplus fiber on the fiber storage can, and jump the other end to the adapter of composite tray. In this way, through cross connection, finish the optical fiber cable circuit connection and adjustment. Its working principle is shown in Figure 8.

(6) When it is unnecessary to dispatch the link fiber cable and branched cable, they can be welded directly, and the excess fiber can be stored on the fiber coiling tray.

4.  For small capacity external optical fiber cable (not exceeding 12 cores), the fiber splitter is not required, and it is only necessary to bind up and fix it, and fix the strength member onto the fixing position of cable core.
