Transponder, DWDM, Client Side XFP, LR, 9.953 to 10.709 Gb/s (WRT-840)

The JDSUWaveReady™WRT-840 multi-rate, bidirectional transponder converts short-reach 10 Gb/s optical signals to long-reach, single-mode dense wavelength division multiplexing (DWDM) optical interfaces. The module is used with WaveReady 3000-series shelves to enable DWDM applications such as fiber relief, wavelength services, and Metro optical DWDM access overlay on existing optical infrastructure. Supporting dense wavelength multiplexing schemes, the WRT-840 can expand the useable bandwidth of a single optical fiber to over 300 Gb/s.

The WRT-840 provides a standard line interface for multiple protocols through replaceable 10G small form-factor pluggable (XFP) client-side optics. The data rates and typical protocols transported include synchronous optical network/synchronous digital hierarchy (SONET/SDH) (OC-192 SR1), Gigabit Ethernet (10GBaseS and 10GBaseL), 10 G Fibre Channel (10 GFC) and SONET G.709 forward error correction (FEC)(10.709 Gb/s). The module supports 3R operation (reshape, retime, regenerate) at supported rates.

The WaveReady WRT-840 also has advanced demarcation capability for carrier services, including loopback testing, power monitoring, and other features. These functions facilitate fault location and correction and simplify operations required by service management and service level agreements (SLA).

Locally and remotely, the WRT-840 can be managed over the in-band management channel through a WaveReady communications module and 3000-series shelf. It also supports both TL1 and simple network management protocol (SNMP) management.
