(1) BBU and RRU are equipped with color optical modules (wavelength range 1271nm~1611nm), combined with passive wavelength division multiplexer, can realize one-core transmission, which greatly saves transmission optical cable resources

(2) A maximum of 9 signals (ie 9 RRU/AAU and 1 BBU/DU) can be realized, which can solve the problem of fiber resource shortage

Passive WDM solution for 5G fronthaul

In application, it can be divided into two-star, bus and other networking topologies according to specific scenarios.

Features of passive WDM solutions

(1) It is completely transparent to the service signal and can be connected to the service of any rate
(2) Channel expansion and transmission of wavelengths from 1271 to 1611 can be realized
(3) Passive products, plug and play, no configuration, simple maintenance;
(4) Small, lightweight, easy to install, and flexible to place; it can meet the needs of a variety of installation scenarios, including: indoor racking, indoor wall hanging, outdoor cabinet, outdoor wall hanging, and outdoor optical distribution box.
(5) Low insertion loss, high isolation, low polarization sensitivity, high return loss, excellent optical performance indicators, and does not affect the transmission quality of optical signals
(5) Good compatibility, can be applied to RRU/BBU equipment of mainstream manufacturers such as Huawei, ZTE, Ericsson, etc.
