GLSUN offers 6 Wavelengths WDM Module with features on low insertion loss, small module dimension
and excellent reliability for 5G fronthaul. GLSUN 6 wavelengths CWDM is coarse wavelength multiplexing/demultiplexing module combined with optical switch. Support bidirectional 6 CWDM wavelengths and each wavelength has PD for optical power detection. The COM port supports primary and backup optical path switching and bidirectional optical power detection.
Semi-active WDM: Passive colorful optical modules and multiplexer/demultiplexer units are deployed at AAU side, and active WDM equipment is deployed at DU side. Multiple AAUs share a fiber for transmission, and no power supply is required at the remote end.
In 4G era, because of low requirements for protection and monitoring, passive CWDM has been widely used due to its mature industry chain, power-free, and plug-and-play features. However, after entering 5G era, in the face of the contradiction between the high reliability of 2B service, the management of massive CRAN networks, and the limited number of operation and maintenance personnel, the application of semi-active technology has become a solution for how to meet new requirements of 5G era.
This is a possible schematic of a hybrid optical-wireless integrated network incorporating PON architecture. It consists of an optical headend or central office that acts as the gateway to the optical metropolitan backbone while serving a large number of optical network units (ONUs) for wired applications and antenna base stations for wireless applications. In this integrated network, the wired data and wireless signals from the trunk network are combined in the central office before distribution to the respective wired and wireless customers via a remote node (RN) or a hybrid wired/wireless base station (ONU/BS).
In the following subsections, we will review different wireless-PON integrated architectures and the enabling subsystem technologies to efficiently transport both wired and wireless signals while maintaining maximum signal transparency.
