First, the fiber optic wiring box (FTTH fiber optic sub-fiber box) Indoor Wall Mount Fiber Enclosures (hereinafter referred to as "fiber enclosures") is mainly used in residential, building or campus and other fiber access network, base stations and other indoor fiber optic network coverage wiring connected to the network, is the fiber into the area, and other parts of the building or campus wiring devices of choice. The product is a fixed set of fiber optic cable, fiber optic splice tray storage and wiring plug interconnection and other functions into one, enabling the signal cable and drop cable interconnect master cells, buildings or campuses. Second, the characteristics ◆ set fixed cable, optical disk storage and welding, wiring plug interconnection and other functions. ◆ use locks the door lock wiring, to ensure the safety door switch box wiring box. ◆ cable clamping, and aramid fiber reinforced core fixed and other accessories can ensure a good connection between the cable and wiring boxes, cable tensile strength increase. ◆ card-mounted adapter plate for easy installation adapter plate and the separator between. Third, the main technical indicators ◆ Ambient temperature: -40 ℃ ~ + 80 ℃ ◆ Relative Humidity: <85% (30 ℃ when) ◆ Atmospheric pressure: 70 ~ 106KPa ◆ operating wavelength: 850μm, 1310μm, 1550umμm (based on the use of optical fiber may be) ◆ Connector Insertion Loss: ≤0.3dB (connection loss: ≤0.5dB) ◆ Connector Return Loss: ≥45dB (PC), ≥50dB (UPC), ≥60dB (APC) ◆ connection plug life: 500 times ◆ insulation resistance between the chassis and the grounding: ≥1000MΩ / 500V voltage between (DC) ◆ Chassis and ground: 3000V (DC) / 1min (no breakdown, no arc).
