New PWRBlazer™ 3142E Optical Node Enables Operators to Easily Scale Networks and Lower Costs

Harmonic Inc. (NASDAQ: HLIT) today introduced the PWRBlazer™ 3142E, a compact 4×4 scalable optical node that addresses the need for a dense, cost-effective node with forward and return path flexibility. Redundancy and four-way segmentation options, offered in both forward and return paths, enable the PWRBlazer 3142E to economically deliver today’s broadcast services as well as support additional narrowcast services such as VOD, data or telephony. The PWRBlazer 3142E, like Harmonic’s other scalable and environmentally hardened optical nodes, streamlines the process of segmenting the hub-to-home section of the cable network in order to increase the effective bandwidth to and from the subscriber.

“The new PWRBlazer 3142E provides operators with greater density and flexibility to facilitate a wide variety of configurations. Cable MSOs can more easily segment their networks without the significant capital expenditures associated with new plant constructions,” said Harry Chou, Senior Director of HFC Product Marketing for Harmonic Inc.

Ideal for fiber-deep architectures and distribution applications, the PWRBlazer 3142E is easy to configure and includes an ergonomic, rugged, die-cast aluminum housing. The housing supports an easy-to-use fiber management system, dual AC input buses (for redundant network powering), optional backup power pack, RF output module and motherboard. The RF module supports four high-level outputs, power-passing capability, and four-way segmentation in both the forward and return paths. A return mute switch in each RF return path enables operators to individually isolate the source of ingress. An optional status-monitoring transponder allows remote monitoring to ensure network reliability.

Harmonic’s award-winning video stream processing, edge and HFC access systems are deployed by cable operators around the world to power their TV services. The comprehensive portfolio of Harmonic cable solutions will be on display at ANGA Cable 2010, stand #H39, taking place in Cologne, Germany from May 4-6.
