ECOC22: Coherent intros micro-pump lasers for optical access

Coherent introduced I-Temp micro-pump lasers for extended ambient temperature operation in broadband optical access networks.

Coherent’s new industry-leading I-Temp micro-pump lasers are now capable of operating over the extended temperature range of -40 to 85 degrees Celsius, enabling optical amplifiers deployed at the network edge to withstand extreme weather conditions.

“The combination of small size, wide operating temperature, and low power consumption makes the I-Temp micro-pump a perfect solution for environmentally hardened optical amplifiers installed, for example, on utility poles,” said Dr. Richard Smart, Senior Vice President, ROADM Business Unit. “The I-Temp micro-pump leverages differentiated technology at every level of its vertically integrated design, including our GaAs semiconductor laser technology platform, with its proven reliability through decades of field deployments.”

The I-Temp micro-pumps maintain a steady output power of 400 mW with less than 2 W of power consumption and remain optimally wavelength-locked with a fiber Bragg grating, without the need for an internal cooler. They are available with 80 μm PM980 polarization-maintaining fibers and 125 μm HI 1060 bend-insensitive single-mode fibers.

Coherent wins DARPA contract for Space-BACN program

The Defense Advanced Research Projects Agency (DARPA) has awarded contract to Coherent to develop coherent optical transceiver technology for the agency’s Space-Based Adaptive Communications Node (Space-BACN) program. The aim of Space-BACN is to create low-cost, high-speed, reconfigurable, laser-based data links that will enable communications between various government and private-sector low-Earth-orbit (LEO) satellite constellations.

Under the contract, Coherent is specifically tasked with designing and fabricating coherent optical transceivers for a reconfigurable modem compatible with most existing single-wavelength communications protocols and able to readily adapt to work with new waveforms as they are introduced. The goal is to support multiple optical waveforms at total data rates of up to 100 Gbps on a single wavelength, while simultaneously meeting stringent size, weight, power, and cost (SWaP-C) constraints.

“Advances in digital technology, together with falling launch costs, have made it possible for many groups to launch ‘constellations’ of compact satellites possessing a multitude of capabilities, enabled by high-speed laser communications,” said Dr. Chris Koeppen, Chief Technology Officer. “Beyond just defense applications, these satellite arrays offer tremendous potential for low-cost global communications, sensing, imaging, space exploration, and more.”

American Tower tests Infinera's XR optics for point-to-multipoint

Infinera and American Tower completed the first point-to-multipoint coherent optical transmission in a carrier network environment in Latin America. 

This field trial was conducted with Infinera’s XR optics technology over American Tower’s Passive Optical Network (PON) network in Colombia. The trial demonstrated XR optics’ compatibility with existing GPON traffic over a single-fiber PON deployment in a metro regional area.

The proof of concept shows American Tower’s ability to take advantage of the transformative value that XR optics can provide in the company’s existing network infrastructure. 

Infinera said its XR optics could enable network operators like American Tower to dramatically simplify their network architectures and significantly reduce CapEx and OpEx costs while enhancing network scalability. 

“As American Tower is evolving its network in preparation of new Edge Data Center and 5G applications, we are always looking for innovative technologies to help us achieve greater value on our existing infrastructure,” said Paul Choiseul, Fiber CTO EMEA & Latin America at American Tower. “The success of the Infinera XR optics solution over our PON network is the culmination of an idea that was born two years ago, when we shared with Infinera our roadmap to test advanced DWDM technologies over ATC’s PON networks. This technology will allow us to provide high capacity, ultra-low latency solutions over our existing PON networks that will satisfy Edge Data Center and 5G requirements.”

“The trial with American Tower provides another proof point illustrating how Infinera’s digital subcarrier-powered XR optics can be applied to existing networks and can seamlessly coexist with GPON traffic,” said Dave Welch, Infinera Chief Innovation Officer and Co-founder. “This represents a radical shift in the way metro networks can be built, promising a dramatic reduction in TCO, setting a new benchmark in scalability, and increasing service flexibility and velocity.”

Acacia samples 100G coherent DWDM module in QSFP-DD

Acacia Communications has begun sampling a new 100G coherent DWDM pluggable aimed at edge and access applications. 

The new 100G coherent DWDM module , which is offered in the QSFP-DD form factor, is designed to provide scalable traffic aggregation. It also provides an upgrade path to migrate from existing 10G WDM networks to higher-performing 100G DWDM coherent links for new architectures in access networks, such as cable/fiber deep and 5G wireless X-haul applications.

The company said its 3D Siliconization approach, based on silicon photonics, will enable it to achieve high-volume manufacturing with this product. In addition, Acacia’s pluggable coherent solutions in QSFP-DD were designed to enable network scalability to 200G and 400G versions in the future. 

“As with our recently announced 100G point-to-point solutions, Acacia is working to satisfy the requirements of service provider edge and access applications with coherent solutions designed for this market,” said Anuj Malik, Director of Product Management at Acacia Communications. “The benefits of coherent have been demonstrated in the metro, long-haul and submarine markets and, with these new products, Acacia is looking to deliver the same scalability, operational simplicity and improved total cost of ownership to the edge and access space.”

“The edge of the network is evolving, and we’re bringing new solutions to market designed to provide scale and ease of use for new applications around IoT and edge computing,” said Jörg-Peter Elbers, Senior Vice President of Advanced Technology, ADVA. “As service providers upgrade their access and aggregation infrastructure, it is only a matter of time before coherent technologies make inroads in this space. Acacia has been a leading provider of pluggable coherent optics and their latest innovation provides interesting possibilities.”

Acacia samples 100G QSFP-DD fixed wavelength module with 120km reach

Acacia Communications has begun sampling a new 100G coherent pluggable transceiver for edge and access applications with unamplified links up to 120km.

The new QSFP-DD point-to-point (P2P), fixed wavelength, hot-pluggable module provides network operators with a coherent alternative to direct-detect solutions.

Acacia says its coherent P2P solutions are extremely tolerant to fiber types, chromatic dispersion, polarization mode dispersion (PMD), and back reflections. This simplifies installation, especially in edge and access networks because coherent technology ample optical margins to compensate for sometimes challenging fiber conditions. In addition, pluggable coherent solutions in QSFP-DD were designed to enable network scalability to ensure that data rates can scale-up by leveraging the QSFP-DD slots with 200G and 400G versions in the future.

“Acacia has a long-standing track record of driving coherent into new market applications by delivering the technology, scalability, feature set, and innovation that service providers need to maintain and grow their networks over time,” said Anuj Malik, Director of Product Management at Acacia Communications. “Leveraging our 10 years of high-performance coherent transmission expertise, we specifically designed our new 100G coherent P2P solutions to meet the needs of edge and access applications in terms of form factor, power consumption and cost, building on our technology leadership in silicon photonics and low-power DSPs.”

“Technology advancements have reached a point where coherent pluggables match the QSFP-DD form factor of grey optics, enabling a change in the way our customers build networks,” said Kevin Wollenweber, VP Product Management for Cisco’s Routing Portfolio. “100G edge and access optimized coherent pluggables will not only provide operational simplicity, but also scalability, making access networks more future proof.”
