January 12, 2006 State College, PA -- C-Cor has announced the availability of its 1-GHz CWDM 1311-nm Forward Path Transmitter. The company says the transmitter is the first in the industry to be ITU G.695-compliant for CWDM spacing, and utilizes a unique variable optical output power range that significantly reduces spare inventory, decreases the need for optical attenuators, and provides the flexibility to account for unexpected link loss during system implementation.

January 12, 2006 State College, PA -- C-Cor has announced the availability of its 1-GHz CWDM 1311-nm Forward Path Transmitter. The company says the transmitter is the first in the industry to be ITU G.695-compliant for CWDM spacing, and utilizes a unique variable optical output power range that significantly reduces spare inventory, decreases the need for optical attenuators, and provides the flexibility to account for unexpected link loss during system implementation.

The company says the advanced CWDM transmitter is ideal for cable operators looking to leverage their existing network infrastructure, without incurring the significant construction costs associated with additional fiber deployment, to support rapidly growing residential and business services. The transmitter is part of the company's CHP Max5000 high-density headend platform that converges headend, hub, and 1550-nm transmission onto one 2RU scalable system.

According to the company, the CHP 1311nm Forward Path Transmitter provides cable operators with a powerful set of capabilities including: multiplexing two forward and multiple analog return wavelengths on a single fiber; 1-GHz bandwidth that increases forward capacity for advanced services such as HDTV, VOD, HSD, VoIP, and digital simulcast; variable optical output for capex and opex savings; dual, high-isolation, full-bandwidth inputs for simultaneous advanced service deployment of video and telephony without cross-talk impairments; universal local or remote management through a Craft interface or SNMP HMS-compliant interface; and a low profile footprint capable of providing 200 transmitters in a standard rack.

The company says that cable operators benefitting most from the device will be those interested in platforms that expand optical network capacity by using multiple wavelengths on existing fiber. Applications, according to the company, include forward and return service group segmentation, adding Gigabit Ethernet business services, and extending the reach of existing links to new communities.

The company notes that the device should be used in conjunction with a CWDM wavelength allocation plan to maximize fiber capacity. The company also offers planning tools to assist in wavelength planning.
