Optical cable distribution box
It is the core supporting equipment for optical fiber welding, terminal connection and wiring management in optical fiber communication networks. It mainly realizes the fixing, protection, connection and scheduling functions of optical fibers, and is widely used in communication rooms, access networks, data centers, security monitoring and other scenarios. The following is a detailed introduction from the core functions, classification, structure composition, application scenarios, etc
product parameters
Rack-type chassis:
is designed for standard 19-inch rack mount. Common specifications are 1U, 2U, 4U, etc. (1U = 44.45mm), which is suitable for cabinet space;
is mostly made of metal (such as cold-rolled steel plate) or high-strength plastic, which has dust, anti-static and shock resistance.
It contains a fusion tray (for fixing fiber fusion points), a fiber storage slot (for coiling excess fiber) and a heat shrinkable tube fixture to ensure that the welded fiber is neatly stored.
Adapter mounting panel:
This panel integrates fiber optic adapters (such as LC, SC, FC, MPO, etc.) to support the plugging and unplugging of different types of fiber optic connectors. Some panels support high-density installation (, MPO adapter can accommodate 12-core/24-core fiber).
Management accessories:
Fiber optic cable management rings, cable ties, label strips, etc., used to organize jumper wiring, mark link information and improve maintenance efficiency.
According to adapter type: LC type, SC type, MPO type, etc.
According to fiber type: multimode (OM3/OM4), single mode (OS2).
Insertion loss: single-mode 0.2dB, multi-mode 0.3dB (affecting signal transmission quality);
Return loss: single-mode 50dB, multi-mode 30dB (reducing signal reflection);
Compatible core: a single U-shaped patch panel usually supports 12-24 (LC/SC) or 48 (MPO), high-density design can reach 96 or more;
