CWDM Ethernet Access System Overview |
Aurora Networks' CWDM Ethernet Access System is an all-optical, high-speed,
full duplex Ethernet-to-the-business solution that can use the fiber optic portion of
existing hybrid fiber/coax (HFC) infrastructure to bring high-speed data access to
business customers over multiple CWDM wavelengths. Because cable operators can use
existing fiber to the node, including fibers already in use for analog video transport,
to simultaneously deliver high-speed data to multiple business customers, significant
savings are realized on installation and deployment costs.
The CWDM Ethernet Access System provides the cable operator a complete system
solution that includes:
• Aurora’s family of CWDM Media Converters for Fast Ethernet and
GbE transport, with 10 different CWDM wavelengths per fiber
• Aurora’s family of indoor and outdoor optical passives, including
CWDM multiplexers and demultiplexers, single-channel CWDM optical filters and 1310/CWDM
optical filters.
Most of the equipment required in a typical CWDM network implementation can
be viewed in this functional block diagram.
With no active equipment in the field, customers’ data services are not
affected by system power outages. In addition, this scalable solution provides optical
wavelength access per subscriber, allowing for easy data rate increases over the same
wavelength, without affecting other customers.
Every electrical and optical segment of the Aurora CWDM Ethernet Access
System is based on open standards. By conforming to non-proprietary IEEE Ethernet and
ITU CWDM Wavelength standards and open standard remote monitoring (RMON) and simple
network management protocol (SNMP) monitoring and management techniques, existing Ethernet
and optical technologies are brought together to provide a complete open standard solution
that can be used worldwide, delivering data at speeds up to GbE (1000 Mbps) data rates.
Aurora’s remote monitoring and SNMP management capabilities provide monitoring,
control and detailed analysis of key system elements, including the customer premises units,
and can be easily incorporated into existing network management systems.
Providing for flexible and cost-effective deployment of revenue-generating data
services, the Aurora CWDM Ethernet Access System addresses the growing need for high-speed
data access by small, medium and large businesses (as well as schools, medical facilities,
and other public and private venues) and further extends Aurora’s continually evolving
support for cable and telecommunications customers with innovative solutions for the delivery
of video, voice and data services.
