Optical Cross Cabinet
Efficient Communication Hub: A Detailed Overview of Multifunctional Optical Cross Cabinet
A cross connect cabinet, also known as an optical cross cabinet or OCC is a device used for connecting, distributing, and dispatching trunk optical cables and distribution optical cables in communication networks for communication systems, power systems, traffic control systems and cable TV systems.
It has the functions of wiring, splicing, fiber storage and fiber adjustment, and can maintain performance in harsh field environments and resist severe climate changes.
The reasons for using cross connect cabinets are mainly related to their key role in communication networks. Here are some of the main reasons:
Connection and distribution
The cross connect cabinet is used to connect trunk optical cables and distribution optical cables to realize the distribution and dispatch of optical signals. It is an indispensable component of the optical fiber network.
Protect optical fiber
The optical cross cabinet provides physical protection for optical fibers, preventing Prevent the optical fiber from being damaged by the external environment, such as moisture, dust, mechanical damage, etc.
Easy maintenance and management
The internal structure of the optical cross cabinet or OCC is reasonably designed, which is convenient for technicians to perform optical fiber splicing, testing, maintenance and management.
Improve network reliability
By splicing and distributing optical fibers in the cross connect cabinet, the reliability and stability of the network can be improved, and network failures caused by optical fiber breakage or damage can be reduced.
Scalability and flexibility
The OCC can be flexibly configured according to network requirements, support network expansion and upgrading, and adapt to changing communication needs.
Support multiple access technologies
The cross connect cabinet supports multiple access technologies, such as FTTH (fiber to the home), FTTB (fiber to the building), etc., to meet different access needs.
Main features of the cross connect cabinet
1. Protection level: The box of the OCC has good sealing performance, and the protection level reaches IP65, which can adapt to various harsh environments.
2. Modular design: reasonable layout, multiple functions, high density, easy to expand and maintain.
3. Anti-theft safety: adopts anti-theft door lock shape, safe and reliable, with good anti-destruction function.
4. Adapter configuration: FC or SC type adapter can be used, and the adapter is designed with a 40° angle to avoid arc light directly hitting the human eye.
5. Grounding system: There are two layers of ground in the box, one is the protection ground, and the other is the rack ground. The two are not connected to each other to ensure safety.
6. Optical cable direct welding area: There is a special optical cable direct welding area in the box to facilitate the connection of optical cables.
Application scenarios
The OCC is widely used in FTTH access mode, placed in the community garden or on the roadside, is used to centrally distribute the optical power of the optical signal introduced into the trunk optical cable.
The classification of the junction box can be divided according to different standards. The following are several common classification methods:
1. Classification by material
IP65 grade stainless steel junction box: Made of stainless steel, with a high level of protection.
Unsaturated polyester glass fiber reinforced material (SMC) junction box: Made of SMC material, lightweight and with good protection performance.
2. Classification by capacity
The Optical cross cabinet mainly has several specifications with different core numbers such as 48 cores, 72 cores, 96 cores, 144 cores, 288 cores, 360 cores, and 576 cores.
3. Classification by matching method
Direct fusion junction box: a junction box for direct fusion of optical fibers.
PCL box junction box: a junction box that uses PCL boxes for optical fiber connection.
In summary, junction boxes play a vital role in modern communication networks and are key equipment for achieving efficient and reliable communications. If you need to know more about junction boxes, OMC’s sales and technical teams are always at your service.
