Salira debuts MW-PON

MAY 19, 2008 -- Salira says its multi-wavelength EPON system enables operators to quadruple bandwidth capacity of existing fiber networks using an implementation of CWDM.

MAY 19, 2008 -- EPON vendor Salira Systems Inc. (search for Salira) say it will unveil the what it claims is the industry's most flexible and cost-effective multi-wavelength EPON system at this week's Cable Show in New Orleans.

Known as MW-PON, the new system enables carriers and operators to quadruple the bandwidth capacity of existing fiber networks. Salira says its system uses an elegant implementation of CWDM to increase bandwidth capacity without any upgrades to the outside plant.

"Our goal in designing this product was to allow for maximum flexibility as it relates to deployment topology," explains Jeff Stribling, vice president of marketing and customer service for Salira. "Salira's solution increases the bandwidth capacity of a single fiber strand by a factor of four. This enables carriers and operators to offer individual service level agreements with extremely high-bandwidth or to increase the end-user density reachable on a single fiber."

Salira's MW-PON increases the bandwidth capacity from 1 Gbit/sec to 4 Gbits/sec for each PON link. Traffic is carried over four wavelengths, thereby quadrupling bandwidth that can be transmitted over a single fiber-optic cable, says the company. Moreover, MW-PON's bandwidth capacity is symmetric, meaning end-users can upload data at the same enhanced speeds.

Salira uses SFP modules on the CPE side to allow service providers to re-assign equipment as conditions change. Unlike DWDM options that are costly to implement and change, Salira says its cost-effective MW-PON gives operators the ability to easily re-assign equipment at both the headend and at the customer premises for maximum flexibility.

To demonstrate its ongoing focus on the cable industry, Salira will be exhibiting at the Cable Show in support of the new MW-PON offering from May 18 � 20, 2008.

Salira's products are based on the IEEE 802.3ah protocols for EPON. The company claims it was the first EPON equipment provider to attain MEF-9 and MEF-14 certification status for its Carrier Ethernet services. The company says its EPON platform is ideally suited for the high-speed transmission of voice and data--the most critical applications for business customers. Salira is also working with service providers worldwide to deliver IPTV, high-speed Internet access, and VoIP.
