This new transceiver leverages the 140 GBaud IC-TROSA from Coherent, which was announced and demonstrated at ECOC 2023


Coherent Corp. (NYSE: COHR), a leader in high-speed optical networking technology, today announced the introduction of its 800G ZR/ZR+ transceiver in ultracompact QSFP-DD and OSFP form factors for optical communications networks.

Artificial intelligence and machine learning (AI/ML) applications are accelerating the exponential growth of datacenter traffic in cloud networks, driving the demand for efficient bandwidth upgrades in datacenter interconnects and optical transport networks. 

0 Gbps

The 800G ZR/ZR+ transceivers from Coherent are the world’s first digital coherent optics (DCO) that can plug directly into QSFP-DD and OSFP transceiver slots on IP routers. Leveraging their high output power of 0 dBm, these transceivers can connect routers directly to access, metro, and regional DWDM transport networks without additional intermediary interfaces, eliminating an entire layer of optical equipment and thereby significantly reducing both capital and operational expenditures.

“This 800G ZR/ZR+ pluggable transceiver is built on the 140 GBaud IC-TROSA that we introduced at ECOC in September 2023, which was also an industry first,” said Matthias Berger, Vice President, Coherent Technology. “We continue to advance the state of the art of optical transmission in core networks by leveraging the inherent capabilities of our indium phosphide technology platform. Indium phosphide photonic integrated circuits are differentiated by their high output power in combination with high performance, which enables disruptive use cases such as IP-over-DWDM in metro networks.”

“We demonstrated the new transceiver with 800G 16QAM for metro/regional transmission and with 400G 8QAM for long-haul transmission,” said Dr. Beck Mason, Executive Vice President, Telecommunications. “The module is designed to support multiple modulation formats including QPSK, 8QAM and 16QAM, and multiple data rates between 200 Gbps and 800 Gbps. This 800G transceiver features a high-efficiency indium phosphide modulator and receiver combined with a built-in tunable laser that delivers best-in-class transmission performance and high optical output power.”

Alpha samples of the 800G QSFP-DD DCO ZR/ZR+ transceivers will be available from Q1 2024.

Knowles: Power Divider Basics

Starvoy Technolgies represents Knowles Precision Devices across Canada – the below recently appeared on Knowles’ blog. For further information on the below – reach out to your account manager, or 

Radio frequency (RF) power dividers are designed to split an incoming signal into multiple outputs such that there’s a portion of the original signal’s power in each output. Given their critical function, power dividers play a particularly important role in antenna systems, telecommunications, and signal processing.

Coherent: Datacom innovation in the AI Era

How Coherent is powering innovation in artificial intelligence and machine learning for next-generation datacenters. Blog post from Coherent.

In the world of transceivers, change is the only constant — and we are in the early days of a step- change thanks to advances in artificial intelligence. Finisar (now Coherent) was a pioneer in pluggable transceivers so much so that the name Finisar became almost synonymous with transceivers.

From telecom networks to enterprise datacenters to web 2.0 hyperscalers, much has changed over the past two decades because of evolutionary and revolutionary changes in the key market drivers.
Today, we’re seeing another major market transition, namely the dramatic growth in artificial intelligence (AI) and machine learning (ML). These applications will define the next chapter in the optical transceiver story – a chapter we are already writing here at Coherent.

 It’s an important story because transceivers are a critical if invisible part of the modern world we live in.  Whether we realize it or not, most of us use the fiber optic network and transceivers on a daily basis.

How The Shift to SiC-Based Semiconductors in Military Power Supplies Affects Capacitor Selection

Blog post from Knowles Precision Devices. Starvoy represents Knowles Precision Devices across Canada, for further information on their range of highly engineered Capacitors and Microwave to Millimeter Wave components for use in critical applications in military, medical, electric vehicle, and 5G market segments.

To protect people and critical equipment, military-grade electronic devices must be designed to function reliably while operating in incredibly harsh environments. Therefore, instead of continuing to use traditional silicon semiconductors, in recent years, electronic device designers have started to use wide band-gap (WBG) materials such as silicon carbide (SiC) to develop the semiconductors required for military device power supplies. In general, WBG materials can operate at much higher voltages, have better thermal characteristics, and can perform switching at much higher frequencies. Therefore, SiC-based semiconductors provide superior performance compared to silicon, including higher power efficiency, higher switching frequency, and higher temperature resistance as shown in Figure 1.

As the shift to using SiC-based semiconductors continues, other board-level components, such as capacitors, must change as well. For example, as systems operate at higher frequencies, the capacitance needed decreases, leading to many instances where film capacitors can be replaced by ceramic capacitors.

Why You Need to Use Ceramic Capacitors with Your SiC Semiconductors

In general, ceramic capacitors are small and lightweight, making ceramic capacitors an ideal option for military applications where space and weight are at a premium. When using SiC semiconductors specifically, since the switching speeds are quite fast, high-frequency noise and voltage spikes will occur. Ceramic capacitors are needed to filter out this noise. And for high-frequency power supplies applications, ceramic capacitors are a preferred option because these components have a high self-resonant frequency, low equivalent series resistance (ESR), and high thermal stability.

Knowles Precision Devices: Your Military-Grade Ceramic Capacitor Experts

As a manufacturer of specialty ceramic capacitors, Knowles provide a variety of high-performance, high-reliability capacitors that are well-suited for military applications. At a basic level, they build all of their catalog and custom passive components to MIL-STD-883, a standard that “establishes uniform methods, controls, and procedures for testing microelectronic devices suitable for use within military and aerospace electronic systems.” We also hold the internationally recognized qualification for surface mount ceramic capacitors tested in accordance with the requirements of IECQ-CECC QC32100 as well as a variety of other quality certificates and approvals. For their high-reliability capacitors, they go above and beyond these quality standards and ensure components are burned-in at elevated voltage and temperature levels and are 100 percent electrically inspected to conform to strict performance criteria
