he semi-active WDM products of Accelink are the wavelength division equipment deployed for the fronthaul network of wireless base stations, which are composed of remote passive optical multiplexer and demultiplexer, local active optical multiplexer and demultiplexer (OSP2200 supports 8 slots, OSP3200 supports 11 slots, OSP5200 supports 20 slots) and color optical modules. Through LWDM, MWDW, DWDM and other standard multiplexing technologies, the products realize the convergence of transmission services of multiple optical fibers into one optical fiber for transmission, improve efficiency for the use of optical fiber core, and achieve the purpose of saving optical fiber resources. LWDM, MWDM, and DWDM optical modules support amplitude modulation and multi-carrier frequency amplitude modulation, and support OAM management of optical modules. Semi-active WDM products can provide standard control interfaces, with the functions such as monitoring, protection, management, and alarm, which can solve the problem that "dummy resources" in the fronthaul network cannot be managed.
