Aurora Networks' DT4030N Digital Transceiver is a component of Aurora's Integrated Digital Transport System that combines two major functions into one compact package: digitization of legacy 5–50 MHz RF return path signals and an Ethernet Access Device. The DT4030N transceiver digitizes the legacy RF return path and multiplexes native Ethernet traffic from the optical receiver port of a plug-in the Small Form Factor Pluggable (SFP) Multisource Agreement transceiver module into the return transport system. By providing virtual pipes for Fast Ethernet services and legacy RF return on a single fiber, the DT4030N Digital Transceiver alleviates fiber exhaustion, greatly simplifies the network and provides distinct time-to-market advantages in turning up new revenue bearing services, including voice, video and data services.

The DT4030N transceiver supports both point-to-point and concatenated applications. For concatenated applications, multiple DT4030Ns can be designed into a daisy-chained configuration. The module's optical transmit/receive ports are implemented with optional plug-in transceivers for ultimate flexibility and affordability. Conforming to SFP, these state-of-the-art transceivers are available in a variety of transmit/receive wavelengths, including dedicated 1310 nm (for 10 and 40 km links), 1550 nm (for links up to 40 km), and CWDM ITU-grid (for links up to 40 km), all operating at data rates of 2.125 Gbps. Longer spans are supported by using Aurora's DX4515 Digital Transponder.

The DT4030N is designed as a plug-in module for Aurora Networks' NC4000 series Optical Nodes. Aurora Networks supplies DT4030N transceivers either with the NC4000 as a fully configured and tested node or as modules for existing customers of the NC4000 desiring to implement digital return and/or upgrade to Ethernet transport capability.

DT4230N Digital Transceiver (5–50 MHz, 2 RF Inputs)

Aurora Networks' DT4230N Digital Transceiver is a component of Aurora's Integrated Digital Transport System that digitizes two discrete legacy 5–50 MHz RF return path signals from separate inputs. The module's optical transmit/receive ports are implemented with optional plug-in transceivers for ultimate flexibility and affordability. Conforming to the Small Form Factor Pluggable (SFP) Multisource Agreement, these state-of-the-art transceivers are available in a variety of transmit/receive wavelengths, including dedicated 1310 nm (for 10 and 40 km links), 1550 nm (for links up to 40 km), and CWDM ITU-grid (for links up to 40 km), all operating at data rates of 2.125 Gbps. Longer spans are supported by using Aurora's DX4515 Digital Transponder.

These dual channel/dual segment (or "2-fer") digital return transceivers allow twice the amount of information to be transmitted over the same fiber cable. Ideally suited for use in hybrid fiber/coax (HFC) and fiber deep architectures, Aurora's "2-fer" digital return path products (including node-hosted transceivers and headend dual channel receivers) support cost-effective growth in high-speed data and telephony penetrations by putting twice as much data onto the same fiber through two discrete return channels of upstream data from the optical node. Each channel is received independently by a dual channel receiver and routed through discrete RF return outputs. This operation provides fiber availability for additional return path bandwidth and rack space for additional return path receivers. Aurora's digital return products enable existing optical nodes to be fully segmented, with each RF input port treated as a discrete network, maximizing the available bandwidth per user, while at the same time conserving the cable operators' investment in the fiber network.

The DT4230N is designed as a plug-in module for Aurora Networks' NC4000 series Optical Nodes. Aurora Networks supplies DT4230N transceivers either with the NC4000 as a fully configured and tested node or as modules for existing customers of the NC4000 desiring to implement digital return and/or upgrade to Ethernet transport capability.
