XKL launches DQT10 transponder
This transponder multiplexes waves outside of XKL’s typical integrated 1RU form factor, allowing network growth to 96 channels.
“At XKL, we are always looking for ways to innovate and give control directly to the customer,” comments Chad Lamb, Director of Engineering for XKL. “The DQT10 allows for seamless bandwidth upgrades and simple pairings between 10G and 100G products for increased capacity. What I like best about DQT10 is its use of alien wave injection to expand existing optical transport networks that could have been provided by a di erent vendor. That kind of flexibility is what today’s customers are looking for.”
link issues in an already operational network. “The 10G market for WDM equipment continues to be robust with 10G port shipments forecast to grow through 2017,” commented Heidi Adams, Senior Research Director of analyst firm IHS Markit. “With the addition of this transponder to its portfolio, XKL recognises the continuing importance of delivering reliable, modular and flexible 10G solutions into this market, while also evolving to meet customer demand for improved scale and e ciency.”
circuits between any pair of clients in a topology by soft- selecting the pathway. The transponder is field- upgradable from 120G to 240G to 360G and can grow up to 96 channels with 960G of bandwidth in 4RU of rack space. O ering customers improved control of their bandwidth future, the DQT10 system is easily integrated with 100GE products, to further increase bandwidth capacity.
XKL LLC has launched its latest DWDM solution, the DQT10 transponder, which is an extension of the DQM10 family of DWDM appliances. The device multiplexes waves outside of XKL’s typical integrated 1RU form factor, allowing network growth to 96 channels and augmentation of existing networks via alien wave injection. Designed with network architecture flexibility in mind, the DQT10 has an integrated digital ROADM providing Add/Drop functionality with soft-select configuration that implements the creation of

Yokogawa announces higher-performance successor to AQ6315A
The new AQ6374 is the successor to the Yokogawa and Ando-branded AQ6315A wideband optical spectrum analyser and includes di raction grating- based monochromator technology, an enhanced user interface and an air purging feature. Yokogawa has enhanced the control technologies originally developed for the AQ6370 series, with the AQ6374 model now achieving measurement speeds up to 40 times that achieved by the AQ6315A. The ability to sample 100001 points of data, 100 times as much as the AQ6315A, enables high resolution measurement over a broad wavelength range, while data-transfer rates during remote control via Ethernet are up to 100 times faster. The measurement performance achieved by the monochromator technology includes a wavelength resolution setting from 0.05 to 10 nm, a wavelength accuracy of ±0.05 nm (at 633 and 1523 nm) or ±0.2 nm (from 350 to 1700 nm), a level accuracy of ±1.0 dB, level
