Optical transfer box is the abbreviation of optical cable transfer box. It is a transfer equipment that provides optical cable termination and patching for trunk layer optical cables and distribution layer optical cables. After the optical cable is introduced into the optical cable transfer box, after being fixed, terminated, and distributed, fiber jumpers are used to connect the trunk layer optical cable and the distribution layer optical cable. Optical cable transfer box is a wiring device used to connect trunk optical cables and branch optical cables in optical cable communication networks, and to terminate, protect, connect and dispatch and manage optical cables and optical fibers. It has the functions of optical fiber splicing, storage and wiring, and can be installed in floor-standing, overhead, wall-mounted or pole-mounted installation methods.
Introduction
Box material: grade stainless steel, unsaturated polyester glass fiber reinforced material ()
Reference dimensions (length, width and height):
Installation method: floor-standing, overhead , pole type, wall-mounted
Application scope: The optical cable transfer box is an interface device used for the trunk optical cable and distribution optical cable nodes in the optical cable access network. It has the functions of optical cable splicing, straight-through, optical fiber storage, and wiring. .
★ Remarks: The above sizes are regular sizes. If special specifications are required, they can be customized according to customer requirements.
Classification
According to material classification, it can be divided into high-grade stainless steel and unsaturated polyester glass fiber reinforced materials ().
According to capacity classification, optical cable transfer boxes mainly include core, core, core, core, core, core, core, core, core, core, core.
Structure
General optical cable transfer boxes are composed of: box body, integrated splicing tray, optical cable fixing plate, and fiber hanging column.
Features
The transfer box has the functions of wiring, welding, fiber storage and fiber adjustment. It has the performance of tenaciously resisting the outdoor environment, and can withstand severe climate changes and harsh working environments. The box is sealed The performance is good and the protection level meets the grade requirements.
The box can be opened from the front or from the front and back. There is sufficient space for fiber cloth and fiber storage in the box, as well as enough winding reels and thread hanging hooks to facilitate user operation.
Modular design, reasonable layout, multiple functions and high density.
It adopts anti-theft door lock shape, which is safe and reliable, and has good anti-vandal function. The box has a flexible incoming and outgoing optical cable structure and a flexible internal connection structure.
You can use an or-type adapter with a beveled angle to prevent arc light from direct exposure to human eyes.
According to customer needs, the optical cable reinforcement core can also be in the form of an optical cable fixed cover, which is suitable for ordinary and ribbon optical cables.
Grounding method: There are two layers of ground in the box, one layer is the protective ground, and the optical cable reinforcement core is connected to the protective ground. The other layer is the rack ground. The two layers of ground are not connected to each other. They are connected to the computer room ground through their own ground wires.
There is a special optical cable straight-through welding area in the box, and the optical cables at both ends are connected in the straight-through welding area.
The bottom of the box is high and the space is large, which facilitates a larger radius of curvature when the optical cable is introduced, and the installation and operation are convenient.
The rack has a good grounding system.
The plastic parts inside the machine are made of flame retardant materials.
Conditions of use
Working temperature: ℃～+℃
Relative humidity: % (at +℃)
Atmospheric pressure:～
Storage and transportation temperature: ℃～+℃
Moisture-proof, rain-proof, dust-proof and anti-theft comply with standards

Withstand voltage level: The withstand voltage level between the grounding device and the metal workpiece of the box should be no less than (direct current) without breakdown or arcing.
The optical fiber connector loss (including insertion, interchange, repeatability) is not greater than .B.
Optical fiber connector return loss: type B type B type B
Optical fiber connector plug-in and pull-out durability life times
Each surface of the box can withstand a pressure perpendicular to the surface greater than , the vertical pressure that the outermost end should be able to withstand is greater than
functional requirements
. Optical cable fixing and protection functions: Optical cable access, fixation and protection devices should be provided. This device introduces the optical cable and fixes it on the frame to protect the fiber core of the incoming optical cable from damage. The metal part of the optical cable is insulated from the machine. The fixed metal sheath and reinforcing core of the optical cable should be reliably connected to the high-voltage protective grounding device.
． Optical cable termination function: It should have an optical fiber termination device, which facilitates the operation, construction, installation and maintenance of optical cable core and pigtail connections. It can fix and protect the joint part straight without displacement, avoid the influence of external force, and ensure that the core and pigtail of the coiled optical cable are not damaged.
． Line adjustment function: through fiber optic jumper connector. It can quickly and easily schedule the core serial number in the optical cable and change the path sequence of the optical transmission system.
． The protection function of the optical cable core and pigtail: after the optical cable is stripped, the core has a protective device and is fixed before being introduced into the optical fiber termination device.
． Capacity: The capacity of each rack and the unit capacity (determined by the number of adapters) should be stipulated in the product enterprise standards. The optical fiber termination device, pigtail coiling device, adapter card holder, pigtail and adapter should be able to operate within the full capacity range. Complete configuration.
Installation Instructions
. When installing on the floor: First reserve 2 anchor screws according to the installation size on the prefabricated cement base. The anchor screws protrude from the surface of the base for approximately 100 meters. When installing, open the equipment first. Door, pull out the two latches at the bottom of the equipment, and open the equipment base panel. Place the equipment on the cement base, tighten the anchor screws in the base with nuts, close the base panel, insert the latches, and lock Tight panel.
. When installing overhead: Leave a hole in the appropriate position of the platform, and secure the equipment reliably according to the installation dimensions.
