DWDM Reach Extension and Regeneration

The WaveReady WRT-842 is a multirate, full C-band tunable, bidirectional transponder that converts short-reach 10 Gbps optical signals to long-reach, single-mode dense wavelength division multiplexing (DWDM) optical interfaces. Dispersion reach can be as high as 176 km (3000 ps/nm) at +5 dBm output power. Supporting dense wavelength multiplexing schemes, the WRT-842 can expand the useable bandwidth of a single optical fiber to over 400 Gbps.

Automatic Rate Detection

The WRT-842 automatically detects incoming data rates so that no provisioning is required. The WRT-842 provides a standard line interface for multiple protocols through replaceable 10G small form-factor pluggable (XFP) client-side optics. The XFP supports various protocols and reaches including OC-192/STM64 (SR-1), 10 Gigabit Ethernet (10 GigE) (10GBaseSR, 10GBaseLR, and 10GBaseER), 10 G Fibre Channel (10 GFC), and synchronous optical network (SONET) over ITU G.709 (10.709 Gbps).The module supports 3R operation at all supported rates.

Optical Service Demarcation

The WRT-842 also has advanced demarcation capability for carrier services, including remote management, data-rate provisioning, loopback testing, and power monitoring, among others. These functions facilitate fault location and correction and simplify operations required by service management and service level agreements (SLA).

AON and Agile Transmission Modules

The WRT-842 is a tunable transponder in the JDSU Agile Transmission Modules family, products designed for agile optical networks (AONs). The flexibility of the WRT-842 is critical to the successful and rapid deployment of next-generation, Internet Protocol (IP) based voice, data, and video services, which are driving new network management challenges for communications service providers.
