Fierce Telecom: Scaling Optical Networks Far and Wide

Acacia — Thu, 09 Jul 2020 21:48:10 +0000

Bandwidth-intensive data services and applications have been driving continued demands for service providers to architect their networks for growth and flexibility. Client traffic from large bandwidth users such as hyperscale data centers has now reached 400G, thanks to recently introduced 400G port switches, routers and standardized 400G coherent optical modules. However, supporting 400G client traffic across multiple network segments can be a challenge if network operator legacy equipment is unable to address these data rates in an efficient, scalable, and cost-effective manner.

Network operators surveying both terminal and line-system equipment to address this new 400G “currency” paradigm are looking ahead to ensure a certain level of cost-effective future proofing for higher capacity demands as client speeds increase beyond 400G. This article examines how recent advancements in terminal equipment coherent technology and line-system channel capabilities help them achieve that goal.

Advancing Coherent Interoperability with OpenZR+

Acacia — Tue, 11 Feb 2020 00:55:59 +0000

History has shown that adoption of optical transceiver/transponder solutions accelerates when implementable standardization and interoperability are established.

Coherent optical technology, traditionally a closed-system technology with proprietary implementations, is evolving towards a similar path, which will help carriers and hyperscale data center network operators by ensuring multiple suppliers for their critical components.

Fibre Systems: Small Talk

Acacia — Tue, 11 Feb 2020 00:46:29 +0000

This article discusses the opto-electronic integration approach to ensuring networks continue to meet bandwidth demands.

With network capacity demands expected to grow 25-30 per cent per year, driven by applications such as self-driving cars, augmented reality, internet of things (IoT), and 4k/8k video streaming content, network operators are challenged with an ongoing need to deploy solutions that are able to keep up with these capacity demands while being, power, size, and cost efficient.

To: Acacia Customers

Re: Continued Supply of Acacia Products

Dear Valued Customer:

With the recent announcement of Cisco’s intended acquisition of Acacia, we wanted to take this opportunity to provide written assurances and confirm our shared intentions regarding the business you do with Acacia.

Cisco is fully committed to supporting the ongoing development, supply and support of Acacia’s coherent modules, DSPs, PICs, as well as products currently on its product roadmap.
Cisco is also committed to continuing and expanding Acacia’s customer base and to growing new customers. As part of this commitment, upon closing of the acquisition of Acacia, Cisco will honor the obligations outlined in written agreements in effect as of the closing between your organization and Acacia, including: meeting agreed upon lead times, pricing and product warranty commitments, as well as providing product roadmap updates, as needed.

We believe that the acquisition of Acacia by Cisco will further enhance Cisco’s silicon and optics portfolios, and will help accelerate the trend toward coherent technology and pluggable solutions while accommodating a larger footprint of customers worldwide. The team at Acacia will continue operating our business consistent with our practice prior to Cisco’s acquisition announcement, in order to continue to support your business needs through closing. Both Acacia and Cisco are looking forward to the combined benefits that we believe we will be able to provide to all of our customers upon completion of the acquisition.

We appreciate your business and the trust you have placed in Acacia and its products, and we believe that even after the closing of the acquisition, we will continue to be a trusted partner to you. Should you have any further questions, please feel free to reach out to either of us directly.

Sincerely,

CISCO SYSTEMS, INC.

Photonics.com – Trends in Silicon Photonics for Fiber Optic Communication

Acacia — Wed, 09 Jan 2019 00:31:58 +0000

The simplest form of fiber optic communication is coupling a laser to one end of a fiber, turning the laser on and off to transmit ones and zeros, and connecting a photodetector to the other end to record the photocurrent. This simple modulation format is called on-off keying (OOK), and the reception is called direct detection.

Coherent communication

Besides optical power in single-mode optical fiber, phase and polarization are two additional orthogonal dimensions that can be used to transmit information. Coherent communication uses these three dimensions, increasing the fiber’s data-carrying capacity by at least a factor of four in gigabits per second (Gb/s). Today, a capacity increase of a factor of 12 is deployed, which is achieved as a result of the receiver’s ability to read the amplitude and phase of the signal. Equalization permits practical complex multilevel modulation, such as 16-QAM (quadrature amplitude modulation) (Figure 1).
