Metrobility adds CWDM to metro - New Products/New Services; Metrobility Optical Systems

Metrobility Optical Systems announced that it is introducing a scalable and flexible managed Ethernet CWDM solution for metro access or campuses to its Radiance model family. A cost effective passive optical networking solution to bring fiber optics to the curb, business and home, the R4000 CWDM models reduce the capital expenditure of the channel costs to approximately 1/3 that of DWDM, and reduces the operating expenditures by simplifying the installation, configuration, and management of the network.

Metrobility's R4000 CWDM solution maximizes the use of the existing fiber plant, is simple to deploy, leverages existing Ethernet expertise, and creates a solution that addresses quality of service issues since it is both highly available and highly manageable. Metrobility's CWDM solution utilizes a Gigabit Ethernet line card with wavelength-specific SFP pluggable optics based on the ITU-T industry standard 20nm spacing. The line card, available as copper-to-fiber or fiber-to-fiber, provides an inline electrical conversion mechanism for monitoring the optical power of every link against problems such as poor connections, wavelength degradation, and even physical breaks in the fiber.

Optical power management is accomplished through the company's EFM OAM feature-ready Radiance technology and Metrobility's NetBeacon SNMP Element Management software. Optional line protection and restoration capabilities are also available by providing dual wavelength-specific fiber connections that automatically failover should a link loss occur. The R4000 (1U high, 19 or 23" rack mount) multiplexer is a scalable solution that supports up to 12 wavelengths (from 1350nm to 1610nm) based on the ITU G.694.2 CWDM wavelength grid. Optical add/drop multiplexers provide either point-to-point or ring topologies and can support distances up to 80km without regeneration. The R4000 enables service providers to offer up to 12 Gigabits of bandwidth over a single fiber link. The R4000 is designed to meet NEBS certification requirements.
