Haikou Cabling

Haikou undertake integrated wiring cabling project, the Division I by virtue of hard work, the spirit of good faith for, we have made remarkable achievements one after another in a market economy, and successfully recognized by the market, a large number of projects to prove, relying wholeheartedly do construction, do the best security to the public, we believe that the construction, we do better. Interested parties please feel free to contact us! University campus network using fiber optic cabling between buildings campus network fiber optic connection, due to the geographical environment campuses is inconsistent, resulting in large campuses network topology Aiba Drive, North Campus using ring - star topology, South Campus and the Art Institute in a tree topology, adult education college with a star topology, Vocational and Technical College in a tree - a bus topology, the use of armed college bus network topology. By design and construction of the campus network, summed up the following experience (1) Due to the large size of the campus network, the geographical environment is complex, network campuses vary and must be in accordance with the principles of the four unified network construction, namely unified planning , unified design, unified construction, unified management. (2) In the wiring design and construction, strong electricity (power lines) and weak (fiber optic, twisted pair, telephone lines, cable TV lines) cables must be separated from the wiring interval of at least 1 m or more, and do not cross your travels. This can effectively prevent the weak of strong electrical interference. (3) In order to ensure signal quality, length of twisted pair to the information from the patch panel module must not over 90 meters, information module to the user terminal cable length should not exceed 10 meters, special requirements of the port from the switch to the terminal computer line Cable length should not exceed 100 meters, or will cause significant signal attenuation. If the user terminal to a cable length of over 100 meters the main distribution frame, an effective solution is an additional signal amplification HUB, if the terminal is a large room, it can use HUB to be connected in cascade. (4) To ensure 1000Mbps bandwidth to the building, the largest single segment of multimode fiber length can not be more than 600 meters, the distance from the main wiring between buildings over 600 meters, will have to use single-mode fiber connections. (5) redundant design. In order to ensure the stability and reliability of the system, but also to facilitate future expansion, from three switches to port two switch from fiber to twisted pair, you must have redundancy. The room should be equipped with two main center three switches each other hot backup; to fiber each building must be at least 4 core (preferably a 6-pin), two of the core as a normal connection, and the rest as a backup; at least in each room There are two information outlets, a telephone interface and a CCTV interface module should have two pieces of information for each information outlet, one for normal use, and the other as a backup. When? (6) may also be twisted pair telephone line wiring, its performance is better than ordinary telephone lines, but the high cost, but for the same room more than one phone, using twisted pair is the best solution, This is because a four pairs of 8-core twisted pair telephone connection 4. ?
