Triple-Stone Launches 5G Fronthaul Application Circulator

发表时间:2020-04-26 00:00

5G fronthaul traditional passive wavelength division uses 1271 ~ 1371 nm 6 wavelength + 1471 ~ 1571nm 6 wavelength, total 12 wavelength CWDM color light module, but the cost of 1471 ~ 1571nm optical module is higher. In order to solve this problem, Triple-Stone released a circulator for 5G fronthaul applications. With this solution, 12-channel bidirectional communication can be achieved using only 1271 ~ 1371 nm 6 wavelength, thereby avoiding the use of relatively expensive 1471 ~ 1571nm optical modules.

     The function of a circulator: Port 1 to port 2; port 2 to port 3

     Traditional WDM:

      1.Need to use 1271~1371 nm + 1471~1571 nm WDM, total 12 wavelength

     WDM structure

    Triple-Stone circulator WDM solution:

1.only needs 1271~1371 nm

    The structure after using a circulator:

     The advantages of using circulators:

   1. Only need to use the general optical module in the industry from 1271 ~ 1371nm, avoid using the high cost 1471 ~ 1571nm

   2. Support bidirectional communication with the same wavelength

   3. 6 wavelengths can achieve 12-channel bidirectional communication
