Optical Communication and RF Components

Built on more than 20 years of product innovation, TeraXion has developed an unmatched expertise in FBG technology used to deliver reliable chromatic dispersion management modules and narrow bandwidth optical filters for the dense wavelength-division multiplexing (DWDM) optical communications industry.  Moreover, TeraXion provides very narrow-linewidth DFB lasers to support analog and digital transmission in optical fiber links.

The move towards a hyper-connected world is forcing the optical communications landscape to evolve at an astounding speed. Many new services, such as enhanced broadband experience, cloud-computing and secure quantum communications are driving this change. As the transition to this hyper-connected world is accelerating, end-user expectations are also growing, leading to the generation of an ever-increasing quantity of data that must be transmitted.

The bandwidth demand created by this massive circulation of information stresses networks, particularly access networks, from data center interconnect to access networks. This leads operators to increase their networks’ capacity while keeping the cost-per-bit at a minimum. A reliable and effective way to achieve this is to use DWDM, intensity modulation direct-detection (IMDD) solutions.

TeraXion provides a range of chromatic dispersion management and emulation products that address the current expansion needs and enable researchers to develop next-generation solutions at a reasonable cost.

DCI & access DWDM systems

East-to-west traffic among regional and distributed data centers is increasing rapidly. To meet this demand, interconnect data rates must increase from 10 Gbps to 100 Gbps. Direct-detection solutions, such as 100G DWDM PAM4, addresses the major cost-per-bit concerns of operators; however, chromatic dispersion is becoming a growing challenge as data rates and distances continue to rise. The TDCMX-SM efficiently manages chromatic dispersion in point-to-point links, enabling direct-detection transmissions of up to 80 km using a single, simple module.

The continuous increase in data rates is also reflected in access and enterprise networks. Once the mainstream in long-haul networks, DWDM architectures at 10 Gb/s and 25 Gb/s are getting closer now to end users through access networks. In many cases, the reach of these systems is limited by optical fiber chromatic dispersion.  To overcome this limitation, TeraXion has delivered several tens of thousands of its flagship DCML solutions, which are compact and low-latency dispersion compensation modules that significantly extend the reach of any DWDM signal at 10, 25 and 100 Gb/s.

Radio frequency over fiber

High-end applications that require the transmission of RF signals using photonics benefit from the low loss and lightness of optical fiber combined with the high-speed response of optoelectronic components. In these applications, an optical carrier is used to transport RF information over an optical fiber, and the RF signal may consist of one or more RF subcarriers modulated by analog signals.

TeraXion’s PureSpectrum™ lasers provide a low-noise, stable optical carrier for RF photonic links, whereas TeraXion’s suite of high-isolation, narrowband FBG filters allows efficient side-band suppression and signal isolation for a much improved spur-free dynamic range (SFDR) for the link.
