Previctry Premises Wiring System Experts
Fiber-to-the-desk Wiring System

With the video conference system and Internet vod system, multimedia communication etc. Various value-added services.The development of the line for clients, higher bandwidth, usually adopts high Copper system to enhance the bandwidth, but from long-term development, optical fiber transmission system is still the best Channel, especially the zero water peak single-mode optical fiber system, optical fiber to the desktop/metope is right .The bandwidth solutions.

Systems usually consists of the following parts:

1, client fiber optic jumper cables, connecting optical information output and terminal equipment.
2, optical information export: usually placed on metope or desktop, optical fiber interface including ST, SC, LC, MTRJ etc.
Level 3, indoor cable: usually USES distributed or charge for indoor cable type, double cores, also have adopted ZIPCORD), pull chain (main cable connection information level of export and floor of XianXiang match between the management of fiber.
4 and floor level XianXiang: a wall with optical fiber, hanging and rack-mountable interface including ST, SC, LC, MTRJ etc. Equipment: connect the fiber optic jumper cables with equipment and fiber XianXiang floor, can also be connected directly with optic backbone optical fiber XianXiang and level with the light signal XianXiang, directly from the main lead to the desktop.

Optical fiber to the desktop interface type: ST, SC, LC, MTRJ etc
Optical fiber type: 822,000 125um/OM1 multimode fiber, 50/125um OM2 multimode fiber, 50/125um OM3 net of ten thousand multimode fiber, 9/125um single-mode optical fiber, 9/125um zero water peak single-mode optical fiber


Optical fiber to the desktop/metope output information product solutions


1 the optical fiber to metope, export information

For a single user, using standard double cores fiber wall panels, 86 type, type of interface for ST SC, LC, etc
Characteristics: simple, economic, general, metope embedded type, 86 for general box is general 86 panel

Electrical characteristics:

For double double cores fiber, using user gang) panel to double (structure, interface type for ST, SC, LC, etc.
Characteristics: simple, economic, general, metope embedded type, double as generic box is general quality.the panel, my company provides for embedded box.

2 Multimedia structural optical fiber to metope information output

Interface type include: ST, SC, LC, MTRJ etc.
Characteristics: all interface for the Keystone of unified interface to open in panel, multimedia installation of unity and multimedia distribution frames on the surface, and copper RJ45 interface, video and audio interface interface, cable TV, unified interface components installed the metope of multimedia information or desktop export.


Install boxes can install multimedia surface of optical fiber interface

Professional fiber to metope information output
Composition: interface module, panel, fiber fixing ring and bottom boxes
System features:

. Robert interface can be arbitrary combination, can satisfy ST, SC, LC, MTRJ etc, also can satisfy interface RJ45 video, audio, etc.
. Robert has fixed ring optical fiber to fixed superfluous, thereby fiber has enough fixed radius, ensure optical properties.
. Well, after all, the panel fixed the interface module can be removed from the front, easy installation and maintenance.
. Maximum termination, eight ST, SC interface, 16 LC interface.

Level XianXiang matchs fiber
1 . rack-mountable
.Meet ST, SC, LC, MTRJ etc, unified frame of the interface to install.
2 . Hanging wall,
Can directly is hanged on the wall, easy installation, for ST, SC, LC, MTRJ etc.
3 . Optical fiber and jumpers
Provide all kinds of optical fiber and the length of the tail, have different jump line interface type.
Indoor cable

Pull the core cable chain, double single user's needs



The core cable for cable with independent casing, excellent protection, can be in more places truncate the termination.
PDistributed fiber meet the needs of users.

Optical fiber construction standard
In optical attenuation in the same wiring inevitably. The causes of the internal and external has two aspects: the inner attenuation and fiber materials, And external attenuation and relevant construction and installation
Therefore it should be noted that:
You must pay attention to the construction of, don't make by weight or cable hard objects injured. In addition, traction should not exceed set maximum apply.
When turning, optical fiber to turning radius, it should be more than 20 times the diameter of fiber itself.
In the wall or wear, optical fiber, add with floor to protect mouth protection with plastic and will use the flame retardant. The tube filler fill. The building also can advance the amount of plastic pipe laying.
Robert times cloth length not too long 2km (generally) wiring should begin to both sides traction among.
When applied to backbone, optical network. Each floor wiring with at least 6 commonly between the core cable, advanced application is best can use 1 2 core cable from the three aspects of application of backup and expansion to consider.
A long fiber laying, the most important is to choose a suitable path. Here is the shortest path not best. Must pay attention to the land use right of the ground or erection. Possibility.
(3) melting in the operation when foreign
Don't use inferior, the bending deformation, especially has the heat shrinkable tube, such heat shrinkable tube in internal stresses on fiber. May of failure.
In the store, carry, casing. Notice clean. Don't let the sand into the casing.
In operation, the stripping knife cuts. The depth of the cable to grasp well, don't loose casing squashed make optical force.
It is temporary, cable, use the figure 8. Don't let optical disks by torsion.
Use stents, hold cloth fiber cable dish. Don't put it down after using cable from the spools similar to cloth fiber optic don't let by torsion.
The operation, optical fiber into (i.e. do not end when distribution frames) fiber externally too tight.
