Throughout the development of mobile communication society, people pursuit of higher performance network has never stopped, along with the Internet of things, the rise of new technologies such as car networking, Internet age is coming, all things are in the 4G network form of communication network will not be able to meet the huge amounts of equipment connection, such as explosive growth data traffic demand, therefore, 5G will arises at the historic moment, the construction of large-scale 5G network is becoming more and more urgent. However, considering the current carrying capacity of the transmission network, the large-scale construction of the station will certainly lead to a large amount of fiber core resources, which is bound to bring a heavy load to the entire transmission network.
In addition, there are some problems in the construction of transmission network, such as difficulty in property coordination and long regeneration cycle, so it is particularly important to realize the fast reconstruction of access network optical fiber by using fiber core multiplexing products.
In order to meet the requirements of 5G construction, the construction scheme of fast reconstruction of optical cable with fiber multiplexing equipment is proposed. This scheme can effectively solve the problem that the fiber core resources of transmission network are insufficient but need to complete the business access quickly, and can load the access business demand on the limited fiber core resources, thus releasing the idle fiber core to complete the other business access.
As a new type of equipment, optical fiber multiplexing equipment adopts the structure of splitter, and its design, production and procurement all meet operators' management standards. As passive equipment, optical fiber multiplexing equipment does not need to change the original active equipment network architecture, but only needs to be installed in the base station side and optical crossover box to connect the active equipment, which can meet the requirements of various construction scenes and has strong scalability.
In the aspect of network construction, facing the scene of unconditional new laying of optical fiber in the region with insufficient optical fiber resources, the traditional construction scheme cannot meet the requirements of construction period, etc., the adoption of optical and complex equipment can complete the fast reconstruction of optical fiber cable, reduce the consumption of fiber core resources, greatly shorten the time of station construction, and realize fast and large-scale station construction. However, if the optical fiber multiplexing equipment is frequently used, multiple cells may fail at the same time, so it is necessary to comprehensively evaluate the actual situation of the area to determine the construction plan.
In terms of cost management, the era of large-scale 5G network construction is coming. Project construction will face such problems as tight cycle, heavy workload and less resources, etc. The application of optical fiber reuse equipment can greatly reduce the property communication cost, construction time cost and construction cost of pipeline optical cable brought by new optical cable. However, the introduction of new equipment will inevitably increase user training and rework, which will also bring certain labor cost consumption. Therefore, it is necessary to comprehensively evaluate the cost of a single project to ensure that it can save the construction cost after use.
In terms of maintenance, each manufacturer of optical fiber WDM device feature of multiplexing equipment is different, good optical multiplexing equipment better optical performance indicators, transparent transmission channel, the colorful optical module has the characteristics of low insertion loss, which can realize plug and play, no business configuration, so in the maintenance level, should try to choose the appropriate manufacturer and prepare enough spare parts to complete maintenance work, maintenance reliability can be guaranteed. HTF is a reliable choice.
