3U Passive Optical Fiber Expansion Equipment

Product Overview

As the deployment of wireless networks becomes more and more intensive, the scale of large-capacity distributed base stations is also expanding. The deep coverage of base stations requires the location of the deployment to be closer to users. The passive optical fiber expander introduced by Visint® utilizes the characteristics of a single optical fiber that can transmit multiple optical carriers of different wavelengths at the same time. It effectively solves the problem of the lack of optical fiber cable resources between BBU and RRU/DU and AAU in the C-RAN architecture, and meets the requirements for deep coverage and flexible expansion of carrier base stations.

The Visint® Vispace 1000 series base station remote product effectively solves the practical problem of lack of fiber-optic cable transmission resources between BBU-RRU/DU-AAU in C-RAN architecture, and meets the requirements of deep coverage and flexible expansion of carrier base stations. Moreover, it can provide multi-solutions for full scene access and end-to-end loading.

 

Application 1: Passive Solution

Passive solutions need to deploy passive optical fiber expansion equipment between BBU/DU pool and RRU/AAU. Only one pair of optical fibers is required between the passive optical fiber expansion equipment. At the same time, we need to replace the SFP colored optical module provided by our company at the CRU port of RRU/AAU and BBU/DU.

Application 2: Active Solution 

Active solutions need to deploy active optical fiber expansion devices between BBU/DU pool and RRU/AAU. Only one pair of optical fibers is required between the active optical fiber expansion devices, and the original BBU/DU devices and RRU/AAU devices do not need to be changed. Plug-and-play, it supports mixed transmission of other types of services.
