1.2 GHz C-Band DWDM Forward Transmitters
ARRIS CHP CORWave® 3 1.2 GHz Forward Transmitters provide operators with significant operational and system benefits. Featuring the lowest power consumption among comparable forward transmitters in the industry, the CORWave 3 enables operators to decrease their headend footprint and significantly reduce powering costs. In addition, the CORWave 3’s industry-leading Dual Density, with two transmitters in a single-wide application module, allows cable operators to add other application modules for new capacity and new services without increasing their current footprint. The CORWave 3’s superior density also supports a 50% decrease in the number of physical devices operators need for forward path transmission, providing additional cost and power savings.
Reduce Complexity and Headend Space
The CHP CORWave 3 Dual Density is optimized for analog and digital channel loading. Available with front and rear fiber connections, the CHP CORWave 3 is backwards compatible with all current and legacy CHP chassis. It features two wavelengths in one single-wide application module to simplify operations, provide less headend “plumbing,” and provide easier module management. In addition, the CORWave 3 multiwavelength plan allows operators to reclaim fiber by leveraging their existing fiber infrastructures for u p to 44 multiplexed C-band wavelengths with a long reach over a single fiber.
Lower RF input allow s for less amplification in the headend, which reduces space and power consumption. To further reduce space in the headend, the single Broadcast input is internally split to both lasers, which reduces the number of external splitters and external cabling that is required.
CORWave 3 transmitters come equipped with tunable lasers, which provide the ability to tune up or down. This feature reduces the required spares, saving operators capital and operational expenses.
Add Value to Existing Assets
Operators with a large base of active CHP Headend Optics Platforms can transition seamlessly to CHP CORWave 3 Dual Density. By doing so, they can deploy new, revenue-generating services, reduce complexity for existing deployments, and transition easily to new CHP installs. For added operational value, operators can monitor CORWave 3 transmitters via the CORView Element Management System, which provides an intuitive and user-friendly interface for security, discovery, configuration, and inventory functions.
