Harmonic launches transmitters for squeezing more TV out of fibre

Michelle Clancy | 18-10-2012

Harmonic has launched a new family of compact transmitter modules to resolve key issues facing operators today — head-end real estate, power consumption and fibre availability. The goal is to make it easier for an operator to deliver high-speed data, IP video, high-definition video and time-shifted TV from a cable operator's existing fibre infrastructure.

"Harmonic's new optical transmitters allow cable operators to do more with less by saving precious rack space, optimising fibre usage, increasing operational efficiency and reducing overall expenditures as they continue to roll out bandwidth-demanding services," said Gil Katz, vice president of the Edge and Access business unit at Harmonic. "The transmitters also complement our recently announced NSG Pro Converged Cable Access Platform system by extending benefits such as high density and power efficiency to optical devices in the cable head-end."

The SUPRALink SPL 7210S DWDM and PWRLink 4200S DFB transmitters feature ultra-high-density optics and a compact design. They can support up to 20 transmitters in 3-RU, effectively doubling the amount of transmitters that can be added to the given rack space, resulting in a significant reduction in power consumption and enabling cost-effective delivery of additional high-quality, bandwidth-intensive services.

Designed as a universal replacement transmitter, the SUPRALink SPL 7210S DWDM offers a 40% deeper fiber reach than standard 1310-nm systems at a comparable price point, Harmonic said.

Up to 20 SUPRALink SPL 7210S or PWRLink 4200S modules can be mounted in the 3-RU Harmonic HLP 4800 broadband platform, thus reducing space, power and cooling requirements, thereby lowering an operator's operational expenses.

The transmitters can be combined with Harmonic's edgeQAM and node family. Harmonic is demonstrating both at the SCTE Cable-Tec Expo.
