Since ultramodern times, due to the material and chemical parcels of optic filaments that have been extensively used in dispatches, medical, computer, and other diligence, a series of products similar as fiber access terminal and optic fiber boxes have also been developed in large amounts. In itself, this material is a huge advantage in terms of communication.

1. Fast transmission speed optic fiber access can give high-speed bandwidth of 10 Mbps, 100 Mbps, and 1000 Mbps; realize two-way data coetaneous transmission, fast Internet speed, stable quality, low packet rate, and further security, which can meet the requirements of druggies for colorful services. Conditions, similar as CRM, ERP, videotape, voice, VPN, etc.

2. Long transmission distance the optic fiber connection distance can reach 70 kilometers; the attenuation is small, and the attenuation per kilometer of the optic fiber is further than an order of magnitude lower than the attenuation per kilometer of the communication coextensive string with the largest capacity; The operating frequency is 8 to 9 orders of magnitude advanced, so the developed capacity is veritably large.

3. Stronganti-interference capability, because optic fiber is an anon-metallic dielectric material, it isn't subject to strong electric hindrance, electrical signal hindrance, and lightning hindrance, and has strong anti-electromagnetic palpitation capability and good confidentiality.

4. The optic fiber network provides data services and has a complete monitoring and operation system, which can meet the requirements of the broadband integrated service digital network in the future, break the" tailback", and make the information trace disencumbered.

5. Easy to expand capacity, a standard optic fiber line with a bandwidth of 2M can fluently be upgraded to 4M, 10M, 20M, up to 100M, and no need to replace any outfit.
