Overview
The GigaWave® Optical Hub (O-HUB) is a field hardened platform based on the ATX GigaXtend® GS7 1.8GHz Optical Node. Instead of supporting an RF amplifier module in the base, the O-HUB has no RF circuitry and is entirely based on digital optics distribution. It supports optical amplification for long distance transport as well as optical switching for redundancy.
A fully loaded GigaWave O-HUB supports up to four Erbium Doped Fiber Amplifiers (EDFAs), two optical switches, four dispersion compensation passives, a controller card for status monitoring, and up to two AC/DC power supplies. Each EDFA features interstage variable gain of up to 25dB and delivers flat amplification across the C-Band DWDM spectrum, supporting ITU channels 15 through 63. To streamline integration and simplify operations, the platform shares the same power supplies and hardened housing as the ATX GigaXtend GS7 1.8GHz Optical Nodes and legacy Cisco® GS7000 Nodes.

Benefits
EDFA, C-Band Optical Amplifier
The GigaWave O-HUB EDFA is a dual-stage Erbium-Doped Fiber Amplifier designed to increase network reach with up to +20dBm output power and variable gain up to 25dB. Up to four EDFAs can be installed in the Optical Hub lid alongside optional Dispersion Compensation Modules. GigaWave EDFAs can also be paired with external/removable interstage Dispersion Compensation Modules (DCMs) of up to 40km.
Optical Switch
The GigaWave® O-HUB Optical Switch provides seamless optical path redundancy, ensuring service continuity during fiber cuts or signal degradation. Up to four switches can be installed in either the hub base or lid (space permitting).
Optical Passives
ATX’s GigaWave portfolio includes a variety of Optical Passives to complement the company’s digital optical transport and amplifier solutions. These field-hardened, low-insertion loss filters are designed for use in indoor and outdoor environments and provide flexible options for multiwavelength applications.
Solution: Distributed Access Architecture (DAA)
ATX designed the GigaWave Optical Hub, to enable cable operators to gracefully transition to a distributed architecture. A highly efficient and integrated solution, GigaWave enables MSOs to dramatically expand the capacity of access links, migrate to a Remote-PHY/MAC architecture, push RF generation deep into the network and replace expensive hubs.
