The VSMY98545 features a 42 mm by 42 mm emitter chip, which supports a low thermal resistance of 10 K/W junction-to-pin, and enables high drive currents up to 1 A and pulses up to 5 A.
The emitter’s integrated lens supports a +/- 45° angle of half intensity, resulting in ultra-high radiant intensity of 350 mW/sr at 1 A and 1600 mW/sr at 5 A (pulses). This is more than double the radiant intensity of devices without lenses.
With its extremely high drive current capabilities and optical power to 660 mW at 1 A, the VSMY98545 can replace multiple standard SMD devices, allowing designers to reduce the component count and improve performance in a wide variety of applications. The emitter is optimized for IR illumination in CCTV, gaming, and road cash systems, in addition to long-range proximity applications such as presence detection for wake-up functions in office equipment.
The device released today offers fast switching speeds down to 15 ns, low forward voltages down to 1.8 V at 1 A, and operating temperatures from -40 °C to +95 °C. The VSMY98545 ensures a shelf life of 168 hours and provides a moisture sensitivity level (MSL) of 3 in accordance with J-STD-020. Supporting lead -free reflow soldering, the device is RoHS-compliant, halogen-free, and Vishay Green.
Samples and production quantities of the new VSMY98545 are available now, with lead times of eight to ten weeks for larger orders.
Service Electric deploys Infinera InP transport network
The indium phosphide based PICs will be employed in Pennsylvania and New Jersey
Infinera has deployed its DTN platform across cable operator Service Electric Cable TV & Communications’ new regional network serving customers in Central and North Eastern Pennsylvania and North Western New Jersey.
Service Electric selected the Infinera Intelligent Transport Network for the speed, simplicity and reliability that the Infinera DTN brings to its network.
Service Electric provides residential and commercial cable and telecommunications services, offering a full range of broadband services to its customers.

By deploying the Infinera DTN, Service Electric can quickly deliver services ranging from 155 megabits per second (Mb/s) to 100 gigabits per second (Gb/s). The platform’s operational simplicity allows the existing engineering team to manage the regional network without the need to add additional engineering resources.
“We have a very busy engineering team, so we’re looking for intelligent solutions that simplify network operations and accelerate new service turn-up. This allows us to focus on growing our business,” says John M. Walson, President of Service Electric. “An Infinera Intelligent Network lets us do just that. With one-time optical layer engineering coupled with intelligent software that automates many provisioning operations that were previously manual, the Infinera solution allows our engineers to turn up services quickly. This gives us a competitive advantage with our customers.”
“Cable and telecommunication operators like Service Electric see the value in an optical networking solution that is simple to operate and can deliver on services quickly,” adds Mike Kelly, Vice President of Cable Sales at Infinera.
“The Infinera DTN, enabled by photonic integrated circuits and integrated digital switching, allows operators to add capacity to their network quickly without complicated engineering, and the DTN’s reliability means MSO engineers can spend more time generating new revenue rather than fixing problems in the network.”
Infinera’s solutions for cable operators include the Infinera DTN, an Intelligent Transport platform for long-haul and metro core platform; the Infinera ATN metro edge platform designed to provide scalable optical transport for access and commercial service aggregation; and the Infinera DTN-X platform featuring 500 Gb/s long-haul super-channels. Infinera’s Intelligent Transport Network solutions are widely deployed by major U.S. MSOs in national backbone, regional, and metro applications.
