Wavelength Division Multiplexing OTN Equipment
WDM systems are divided into three different wavelength patterns: normal (WDM), coarse (CWDM) and dense (DWDM). Coarse WDM provides up to 16 channels across multiple transmission windows of silica fibers.

Optical Module OTN
OTN (Optical Transport Network) consists of various optical network elements connected by optical fiber lines. An optical transport network (OTN) is a digital wrapper that encapsulates frames of data, to allow multiple data sources to be sent on the same channel. Our OTN processors and OTN physical layers (PHYs) offer leading innovation, integration and power for Data Center Interconnect (DCI) networks. They deliver the quickest time to market and lowest R&D expense for the OEM and minimize the total cost of ownership for the service provider. This recommendation, sometimes referred to as digital wrapper (DW), takes single wavelength SONET/ SDH technology a step further enabling transparent, wavelength manageable.

Two types of optical transmission modules for OTN
OTN defines a precise layered structure for transporting and managing data: Optical Payload Unit (OPU): Holds the client signal and ensures transparent mapping. Optical Data Unit (ODU): Adds overhead for performance monitoring, multiplexing, and protection. Function diagram 200 Gbit/s transponder/muxponder, aggregating 4x40 Gbit/s and 4x10 Gbit/s into a single 200 Gbit/s /OTU2C standard OTN trunk. Key technologies supported include 3G, 4G/LTE, IMS, Ethernet, OTN, FTTx, and various optical technologies (accounting for an estimated 35% of the portable fiber-optic test market). EXFO has a staff of approxim ately 1600 people in 25 countries, supporting more than 2000 telecom customers worldwide. In-depth coverage of DWDM, OTN, coherent optics, network design, and more — written by field engineers. Glossaries, troubleshooting guides, optical formulas, 80+ infographics, and ITU-T standards references. The diagram titled "The multiple layers of the OTN network" clearly illustrates how the various layers within the OTN framework work together to ensure smooth transport of different client signals, including Ethernet, Fiber Channel, MPLS/IP, and SDH/SONET.
