Dispositivos Ópticos Passivos

Wavelength Division Multiplexing (WDMs) and de-multiplexers combine multiple signals for transport on a single fiber, and separate combined signals for distribution to multiple destinations—increasing the bandwidth available on your existing fiber. 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

Coexistence elements allow you to support multiple services on a single fiber by combining signals from different wavelength. For example, you can offer GPON and XGS-PON over an existing PON fiber infrastructure without changing the outside plant, while being prepared to overlay future 25G or 50G PON signals and enabling test access for OTDR over 1600nm wavelength.

CommScope’s CEx elements are available in four configurations and two housing styles: NG4 and LGX.

CommScope’s CEx elements enable:

• Multiple PON services over existing fiber infrastructure
• Increased speed and performance over GPON systems
• Cost-effective migration to next-gen PON services
• Coexistence of GPON, XGS-PON, NG-PON2, RF video, optical time domain reflectometer (OTDR) and other future technologies
• Prepare for future utilization of unused spectrum through upgrade ports, including overlay of WDM for ethernet
