The pipe gallery construction specification requires that the pipe gallery fiber phone should have three performances

Pipe gallery construction specifications: What performance must the pipe gallery fiber phone have? This is estimated to be unknown to many people. The following 800 Tong Smart will introduce to you, one is dustproof, waterproof and moisture-proof performance; second is anti-interference performance; third is durability, these three points are essential. Let’s take a concrete look at the three performances of the tube corridor fiber phone:

According to the requirements of the “GB50838-2015 Urban Comprehensive Pipe Gallery Engineering Technical Specifications” of the Ministry of Housing and Urban-Rural Development and the General Administration of Quality Supervision, Inspection and Quarantine, it is clearly stipulated that a fixed communication system should be installed in the pipe gallery. In recent years, optical fiber voice telephones have developed rapidly, and optical fiber emergency telephone systems rely on long transmission distances. (Distance 120KM), strong anti-interference, low deployment cost and other advantages, has been favored by highway network departments and urban pipe gallery management departments.

The main three characteristics of the corridor telephone are dustproof, waterproof and moisture-proof performance, anti-interference performance, and durability. In special cabins, explosion-proof telephones are also required as terminals.

Anti-interference performance: Anti-interference performance means to minimize the impact of electromagnetic interference on voice calls and signal attenuation during long-distance transmission during calls and audio signal transmission.

Dust-proof, waterproof and moisture-proof performance: The dust-proof and waterproof performance is based on the national standard "GB4208-2008 Shell Protection Grade". At the same time, according to the pipe gallery engineering specification, its entry index shall not be lower than the IP65 protection level.

Durability: According to the pipe gallery engineering specification, the whole life cycle is defined as one hundred years. Under the PPP model, the owner’s planned life will not be less than twenty to twenty-five years. As an important terminal of the communication system, 800 Tong Intelligence puts forward the concept of "replace once", that is, to improve the durability of its phone in all aspects, ensuring that the design service life exceeds ten years, reaching 12.5 years. In the entire life cycle of the pipe gallery communication system, "replace once" or even reach the standard of no replacement.

As a new concept, the optical fiber phone has been widely verified. It has a self-healing function. That is to say, in a network, hundreds of simultaneous calls can be realized. The host and the extension can communicate at any node, and any extension Failure does not affect the use of other extensions, greatly improving the daily work efficiency and emergency handling capabilities.
