Aurora's DS4004 Optical Ethernet Multiplexer enables delivery of Fast Ethernet over fiber, interfacing with standard media converters such as CPE devices. On the network side, the DS4004 is fully compatible with Aurora's high speed digital transport system and DWDM optical transport technology.

The DS4004 can be used over dedicated fiber or can operate over existing digital return infrastructure, generating additional revenues from spare bandwidth in these systems.

The DS4004 features one high-speed (2.125 Gbps) Network Port and four Fast Ethernet Local Ports, all populated by Small Form Factor Pluggable (SFP) plug-in transceivers for ultimate flexibility and affordability. SFP transceivers are available in a variety of transmit/receive wavelengths, including dedicated 1310 nm, 1550 nm, CWDM ITU-grid, and others. Each Local Port supports a 100 Mbps full duplex wire-speed Ethernet link that is terminated at the customer premises by a standard media converter.

The DS4004 module includes a sophisticated add/drop multiplexing function to serve its 2.125 Gbps Network Port, supporting software controlled add/drop of traffic at 100 Mbps granularity. This feature enables operators to add and drop only the amount of traffic required per site, conserving valuable bandwidth. The DS4004 also includes a Time Division Multiplexing function, serving the Local Ports to provide a high degree of security, low jitter and latency, and wire-speed performance to every customer port.

GE4132M GbE Node PON^® Module

The GE4132M GbE Node PON module is designed to work in any Aurora Networks NC4000 series Node. It enables the availability of GEPON functionality from a standard cable TV HFC node. With this module, cable operators can cost-effectively and selectively migrate an installed HFC network to a standards-based GEPON FTTH network—if and when it becomes justified by bandwidth demand and potential revenue growth. Aurora's Node GEPON solution was specifically designed for MSOs, with special consideration for their installed networks.

The GE4132M OLT enables delivery of 1000 Mbps Ethernet over fiber, interfacing with standard GEPON Optical Network Units (ONUs). The Passive Optical Network (PON) supports a point-to-multipoint fiber architecture with simple optical splitters. On the network side, the GE4132M is fully compatible with a standard Gigabit Ethernet transport that has been implemented with Small Form Factor Pluggable (SFP) transceivers (installed in the Ethernet 1 optical port). A second SFP facility (Ethernet 2 port) is available to support daisy-chaining of the Ethernet backhaul.
