XKL LLC, US optical networking systems provider, unveiled a new product, the DQM400, a four-port optical multiplexing transponder (Muxponder) system, during the NANOG 88 North American Network Operators' Group meeting held in Seattle, Washington this week (June 12-14). The transmission systems supplier stated that the Muxponder simplifies data transmission over optical fibers while reducing complexity.
XKL claims that the DQM400, based on the company's modular XKL DarkStar architecture, is designed for quick installation and deployment in "a matter of minutes." Like all their products, the company designed this system to provide continuous and uninterrupted data transmission while reducing energy consumption, thereby lowering operational costs. The company further added that the control plane of the DQM400 is completely separate from the user data plane, enhancing data security. XKL stated that the Muxponder can easily integrate into existing network infrastructure and management systems.
The DQM400 accommodates four channels of up to 400G each on the client and line sides. The system utilizes QSFP28/QSFP-DD modules on the client side and OSFP transceivers on the line side. The client ports are software-configurable, supporting 100GbE, 2x100GbE, 3x100GbE, 4x100GbE, and 400GbE operations.
The system can be used by operators in various network topologies, including point-to-point, ring, linear, and protected (DMD-a).
Len Bosack, CEO of XKL, commented, "XKL is committed to introducing new technologies and solutions that provide network operators with elegantly engineered innovations, taking usability and network best practices into consideration. Our Layer 1 DWDM systems empower operators to flexibly address today's challenges and prepare for the future. With unprecedented bandwidth expansion, scalability, and enhanced security, we believe this technology will bring greater value to our customers and the industry as a whole."
