Pure passive solution:
The pure passive solution is mainly configured as a passive wavelength division + color light module.
The types of passive wavelength divisions that can be selected are: passive coarse wave division and passive dense wave division. Support channel customization, passive coarse wave division common channel has 6/8/10/12/16. The passive channel is a common channel with 6/8/10/12/16/32/40. The coarse wave division does not support optical amplification, and the dense wave division supports optical amplification, which can be used for a line segment where the optical fiber is lost for a long distance.
The color module speed is 10G and 25G. Corresponding to the wave division, there are also coarse wave modules and dense wave modules, and the specifications are 20/40/80 km.
The configuration and number of the two sides of the pure passive solution are the same, and the same number of passive wavelength division + color light modules.
Semi-active solution:
The configuration of the semi-active solution aggregation data room and the base station are not exactly the same.
The main configuration of the aggregation data room (5G DU or 4G BBU) is: XYT-1600 integrated transmission platform + wavelength division module + color light module + OTU service module + service optical module + optical protection module
The base station (5G AAU or 4G RRU) is mainly configured as: passive wavelength division + color light module.
The main models of the XYT-1600 integrated transmission platform are:
XYT-16104 (1U, support 4 function modules);
XYT-16208 (2U, support 8 function modules);
XYT-16416 (4U, support 16-function modules);
The XYT-1600 integrated transmission platform includes the network management module and supports the visual network management. Through the OTU service module, it can intuitively detect the illuminating situation of each service, and realize the functions of fault diagnosis and accurate positioning, alarm display, alarm statistics, alarm processing, etc. The 1+1 link protection, real-time monitoring of active and standby fiber power, and automatic protection switching can be implemented through the optical protection module. Dual power supply, support AC / DC free choice.
The service optical module has 10G and 25G rates, and is inserted into the OTU service module and the 5G AAU or 4G RRU device to implement service access OTU. The color light module has a rate of 10G and 25G, and is mainly inserted into the OTU service module to implement access to the wavelength division module.
The OTU service module is mainly used for service access and wavelength conversion, and realizes online real-time monitoring of each optical signal to facilitate maintenance and operation.
The optical protection module mainly implements the 1+1 dual link protection function.
Evolution:
By comparing the pure passive scheme with the semi-active scheme, both schemes are configured on the base station side to be the same product: passive wavelength division + color light module. The main difference is the configuration on the side of the aggregation machine room.
Therefore, in order to integrate the above products, there are two implementations to evolve from a purely passive solution to a semi-active solution:
First: In the pure passive scheme, the passive wavelength division + optical module on the side of the aggregation data room is gradually transferred to the base station side, and the data on the side of the aggregation data room is replaced by the XYT-1600 integrated transmission platform + wave division module + color The optical module + OTU service module + service optical module + optical protection module can realize the evolution from a pure passive scheme to a semi-active scheme, and will not cause waste of related products purchased by the purely passive scheme.
Second: In the pre-pure passive scheme, the passive wave division on the side of the convergence machine room is made into a module-type wave division that matches the XYT-1600 integrated transmission platform. When you need to evolve from a purely passive solution to a semi-active solution in the later stage, you only need to add "XYT-1600 integrated transmission platform + color optical module + OTU service module + service optical module + optical protection module" to the aggregation data room side. No waste evolution at all.
The above two schemes are based on the pure passive scheme for the pre-implementation project and the later transition to the semi-active scheme. The program has obvious advantages, simple construction, reusable products, no waste, and reduced data and labor costs. Moreover, the semi-active solution is highly intelligent, enabling remote network management and facilitating maintenance of maintenance personnel.
