XKL releases DQT400 12-port optical transponder

Feb. 14, 2023
The DQT400-12 is configurable and can support forty-eight 100GbE services, twelve 400GbE services, or a combination of 100GbE and 400GbE services

XKL LLC is using this week’s NANOG 87 in Atlanta, GA, to release the DQT400 12-port optical transponder. The new offering expands on the DQT400’s launch port count of four (see "XKL DQT400 Optical Transponder now available in all markets").

The DQT400-12 is configurable and can support forty-eight 100GbE services, twelve 400GbE services, or a combination of 100GbE and 400GbE services – a total of up to 4.8 Tbps of capacity across the transponder. The increased density of the DQT400-12 leads to a lowered power consumption of an estimated 0.1 W per gigabit. Multiple transponders can be combined within a rack to enable 19.2 Tbs of capacity in 5 RUs. Thus, the DQT400-12 can offer a 48-channel configuration in  5RUs instead of the 13 RUs alternatives might require.

“We are consistently seeing data centers and enterprises nearing their 100G limits as the use of data intensive applications continues to grow. As a result, customers are looking for solutions that can help them meet today’s needs while preparing for tomorrow’s increased demand,” said Len Bosack, founder and CEO of XKL. “To help customers address these needs, our team has worked hard to develop the DQT400 12-port optical transponder, which provides customers with an easy-to-install, scalable, and reliable solution to support 100G and 400G deployments.”

The DQT400 suite members can be used for 100G services today and are software-configurable when 400G becomes a requirement. The software-configuration capabilities means no downtime or hardware modifications are required for this upgrade if the system is purchased with DR4 client optics.
