Have you ever been accused of seeming “a million miles away”?  In reality, there are very few human-influenced things that actually are or have been a million miles away.  One exciting new thing that is indeed about one million miles away (932,000 miles, +/-, orbiting the sun in L2) is the James Webb Space Telescope … The post NeoPhotonics and Integrated Optics Pay Homage to Classical Optics in the James Webb Space Telescope appeared first on 100G Optical Components, Coherent, PIC, DWDM ..read more

Benefiting from state-of-the-art Sipho technology and advanced digital signal processor (DSP), packaged in the form factors of QSFP-DD, OSFP, and future OSFP-XD, 400ZR, 800ZR, and 1.6T coherent optical transceivers represent a very cost effective, small form factor, and power efficient solution to replace large, costly, and power inefficient DWDM network transponders from today and well … The post Silicon Photonics (Sipho) – Reliability and Cost Considerations for 400ZR, 800ZR, and 1.6T appeared first on 100G Optical Components, Coherent, PIC, DWDM ..read more

The exploding intra- and inter-data center (DC) traffic is driving the capacity demand of Ethernet switches/routers and optical transceivers at an extremely fast pace. For example, today’s intra-DC spine switch runs at 25.6Tb/s with 32 ports of 800Gb/s pluggable optical transceivers (e.g., 800G-DR8 over 8 pairs of fibers) or 64 ports of 400Gb/s pluggable transceivers … The post 800Gb/s and 1.6Tb/s Optical Transceivers on the Horizon appeared first on 100G Optical Components, Coherent, PIC, DWDM ..read more

High speed optical networks are always on, carrying traffic for data, video and personal communications.  Availability is assumed, but it is determined by factors of product quality and operational reliability.  This manifests in network operating expense for both direct operations and for maintenance or repair. Optical module or components products with poor quality or reliability … The post Optical Product Quality As A Driver of Total Operating Costs appeared first on 100G Optical Components, Coherent, PIC, DWDM ..read more

Lidar sensors with high-level integration are being developed to address the size, weight, and power -cost (SWAP-C) requirements of automotive, robotic, and industrial applications.  With the availability of silicon photonic integrated circuits (PICs) from CMOS fabs, designers now can integrate the transmit and receive functions of the lidar onto highly manufacturable silicon chips and power … The post Quest for Chip-Scale Lidar and the Role of Optical Beam Steering appeared first on 100G Optical Components, Coherent, PIC, DWDM ..read more

In determining the cost to deploy optical modules, one of the often-overlooked factors is power consumption.  Although it’s usually considered as a day 0 specification, it also manifests in long term operational expense (OpEx) through two factors, i.e., (1) direct cost (electricity), and (2) indirect costs (fan power, air conditioning) that may be significantly larger. … The post Benefits of Low Power Consumption and Higher Operating Temperature in Modules appeared first on 100G Optical Components, Coherent, PIC, DWDM ..read more

Traditionally, Coherent transmission technology has been used for connections between datacenters (DCI) while PAM4 has been primarily used for connections inside datacenters (intra-datacenter).  However, as speeds increase the cross-over distance between these two technologies gets shorter.  For example, the one significant application of PAM4 for connection between data centers was Inphi’s ColorZ 100G transceiver with … The post 800G Inside the Data Center – Coherent and PAM4? appeared first on 100G Optical Components, Coherent, PIC, DWDM ..read more

Mechanical Form Factor Evolution When coherent 40 Gb/s transponder was first introduced in 2008, it was a line-card with all components spread out on multiple printed circuit boards (PCBs), as shown in Figure 1. To increase the number of interoperable vendors, the Optical Inter-Networking Forum (OIF) developed Multi-Source-Agreements (MSA) for 100 Gb/s long-haul transponder form … The post Coherent Hot Pluggable Module Evolution and Future Outlook appeared first on 100G Optical Components, Coherent, PIC, DWDM ..read more

Chip scale LiDAR technologies are considered to significantly improve SWaP-C (Size, Weight, Power, and Cost) of a LiDAR system and lead to large-scale adoption of LiDAR devices for autonomous vehicles, ADAS L3/L4 vehicles and robotic applications. Coherent LiDAR, also known as FMCW LiDAR technology leverages photonic integrated circuits developed for coherent fiber optic communication to enable chip-scale LiDAR … The post High-power semiconductor optical amplifiers as the enabling technology for chip-scale LiDAR devices appeared first on 100G Optical Components, Coherent, PIC, D ..read more

Coherent fiber optic transmission systems are now being deployed that transmit 800 Gbps on a single wavelength, which is up from 600 Gbps per wavelength, which was introduced a couple of years ago, and, in turn, was up from 400 Gbps before that, and so on.  It is interesting to ask what improvements to technology … The post Class 60 Coherent Components Enable 800G per Wavelength Optical Transport appeared first on 100G Optical Components, Coherent, PIC, DWDM ..read more
