Optelian’s TMX-2200 is an ideal DWDM transport solution for 100 GbE or OTU4 services. It interfaces to standard 100G SR4 or LR4 client optics, and incorporates a CFP2-DCO pluggable line interface with a software programmable DWDM modulation format that can operate in 100G DP-QPSK or 200G DP-16QAM mode. Up to two 100G client services can be transported over a single DWDM wavelength with optional physical layer encryption. It provides full client- and line-side performance monitoring for clear service demarcation, fault localization, and SLA assurance.


200G Transponder and Muxponder


The TMX-2200 provides efficient transponding and DWDM transport for 100 GbE and/or OTU4 client services. It incorporates a pluggable CFP2-DCO with a software programmable modulation format, and fully-integrated coherent transceiver, including DSP. The line signal can be set to SDFEC for the longest possible reach, or staircase HGFEC for interoperability. It can be used for point-to-point DWDM links of any distance with up to 26 dB link budget, or provide all-optical transmission over 1000 km or more in amplified systems. Integrated physical layer encryption capabilities are also available*. The two QSFP28 client interfaces allow two 100G client signals to be muxponded onto a single 200G DWDM wavelength, or a single 100G client signal to be transponded onto a single 100G DWDM wavelength. The client interface supports 100 GbE and/or G.709 OTU4 protocols using a QSFP28 SR4 or LR4.

The TMX-2200 is compatible with the ITU flexible grid, and 100 GHz and 50 GHz fixed grids, allowing it to be used with existing DWDM OADM and/or ROADM infrastructure. As a Layer 1 networking device, it transports client services at the full 100G data rate with deterministic low latency. The software programmable line interface allows for a trade-off between reach and spectral efficiency, depending on the OSNR of a given wavelength circuit. Where high spectral efficiency is desired for very long wavelength circuits, the reach can be extended to any distance using the RGN-2200 configured as a bi-directional regenerator for 100G DP-QPSK or 200G DP-16QAM wavelengths.
