Optical Communication and RF Components
Built on 18 years of product supply, TeraXion has developed an unmatched understanding of the chromatic dispersion management needs and challenges of the optical communications industry. To address these, TeraXion offers a line of simple and cost-effective products, suitable for DWDM and TWDM-PON high-speed networks as well as lab and research applications.
The move toward a hyper-connected world is causing the telecommunications landscape to evolve at an astounding speed. Many new services, such as enhanced broadband experience, cloud-computing and business connectivity 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 (metro data-center interconnects (DCI), fiber-to-the-premises (FTTx) and 5G X-Haul). 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 and Enterprise Networks
East-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 duo-binary and PAM-4, address the major cost-per-bit concerns of operators, but chromatic dispersion becomes a growing challenge as data rates and distances increase. The TDCMX-SM efficiently manages chromatic dispersion in point-to-point links, enabling direct-detection transmission up to 80 km using a single, simple module.
Access and Passive Optical Networks
Next-generation passive optical networks such as TWDM-PON networks use C-band optics, with data rates of 10 Gbps and beyond. At 10 Gbps, chromatic dispersion can generate system penalties in certain conditions involving reach, data rate and laser type. Once the data rate increases to 25 and 50 Gbps, chromatic dispersion becomes a definite problem and needs to be managed efficiently. Thanks to our leadership in the metro/regional networks, TeraXion is well-positioned to support vendors developing communications systems that will meet new PON standards.
Lab and Research
An ever-increasing thirst for bandwidth is driving the development and deployment of new technologies in the 200 Gbps and 400 Gbps ranges. A critical aspect of this research is the assessment and mitigation of chromatic dispersion effects. TeraXion's line of chromatic dispersion emulation products use exclusive fiber Bragg grating (FBG) technology to replace kilometers of optical fiber with compact benchtop instruments, making these emulators ideal for both laboratories and production floors.
Radio-frequency over fiber
High-end applications requiring 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 suppression of undesirable signals, for much improved spur-free dynamic range (SFDR) for the link.
