波長分割多重 (WDM) とデマルチプレクサは、1 つのファイバーで複数の信号をまとめて伝送し、複数の宛先に分配するため、既存のファイバーで利用できる帯域幅を増やします。They can be applied in core and metro networks, transport networks, hybrid fiber cable (HFC) distributed access architectures and wireless transport, enabling true converged all optical IP communication.
WDM solutions require no power or additional fiber installation, making them quick and easy to install and maintain. The ITU.T has standardized wavelength channels in a Course and Dense WDM grid, offering a path to exploit the full optical spectrum in a single fiber, with the possibility to overlay signals, including coexistence of ethernet communications with PON technology.
CommScope’s WDM portfolio includes a variety of form factors for both CWDM and DWDM, optimal for a wide range of inside plant (ISP) and outside plant (OSP) applications. For example, CommScope’s LGX or NG4 ISP Multiplexing Modules can be used in the headend or central office facility to multiplex signals. They can be paired with FOSC or FIST fiber optic closures containing the matching De-mux modules, or use add-drop solutions optimal for daisy chaining.
With CommScope’s WDM, operators can:
- Support high-speed, high-capacity throughput with low latency
- Improve quality of service
- Make the most out of their fiber investments, for fixed and mobile access, optical transport
- Deploy GPON, CPRI and Ethernet traffic on the same network or fiber strand
- Migrate easily from 1G to 100G, 400G and higher – using latest technologies such as coherent optic transceiver technology
