Optical fiber distribution box
Designed and produced according to the communication industry standard YD/T 2150-2010, it integrates the introduction of optical cable (fixing, peeling, protection), optical fiber fusion, and wiring, and independently completes the optical fiber wiring management function. It is suitable for indoor/outdoor fiber splitters of optical distribution points in optical access network, and its waterproof performance is up to IP65 level.
Use environment:
Working temperature-10 ℃ ~ + 60 ℃.
The storage temperature is-25 ℃ ~ + 60 ℃.
The relative humidity is no more than 95%. Atmospheric pressure 70kpa~106kpa.
Optoelectronic performance of adapter:
Insertion loss (IL) ≤ 0.2dB. Return loss (RL) ≥ 55dB.
High voltage protective grounding device:
The insulation resistance ≥ 1000m Ω / 500V (DC). The voltage withstand voltage ≥ 3000V (DC) / 1min, no breakdown, no flying arc.
Main mechanical performance parameters:
The insertion and unplugging durability life of ZJ connector is more than 1000 times.
The whole curvature radius of the fiber is controlled to ensure that the curvature radius of the fiber is greater than that of 30mm at any position.
It clearly marks each optical fiber to avoid confusion caused by disassembly during maintenance.
Technical requirements:
Hanging wall installation, modular design, high density.
It has perfect optical cable introduction device and grounding protection device, which is convenient for optical cable introduction and fixing, safe and reliable.
Card adapter installation, suitable for SC, FC and other adapters, adapter installation tilt to the front of the chassis 30 °, easy to plug and unplug, easy to install.
Avoid arc light directly into the eye, and at the same time facilitate alignment.
The whole curvature radius of the fiber is controlled to ensure that the curvature radius of the fiber is greater than that of 30mm at any position. The entry and exit of distribution fiber, distribution tail fiber and jumper fiber are independent and do not interfere with each other, and each core is clearly marked.
With the installation of inclination angle, the winding of tail fiber is natural and smooth, and the radius of curvature is large, which can minimize the transmission loss of optical fiber.
The welding box has a cascading structure, which is convenient to increase and decrease, easy to operate, and can be adapted to the fusion of ribbon optical fiber.
The body of the box is tightly sealed with a sealing strip, which can effectively prevent the entry of dust, and adopts electrostatic spray molding, which has a simple and beautiful appearance.
