Firecomms III-V / Silicon Optical Transceivers In Full Production

The firm's new RedLink transceivers incorporate InGaP/InGaAlP/GaAs technology. They are suited to industrial applications and are compatible with versatile link connectors
Firecomms is in full production and is shipping its new RedLink line fibre optic transmitters and receivers for the industrial command, control and communications markets.

Specifically designed to be compatible with Versatile Link connectors from Avago Technologies, the RedLink family of products includes transmitters and receivers which operate from DC-1 Mb, DC-5 Mb, DC-10 Mb and DC-50 Mb.

Firecomms' optical transceivers combine compound and silicon semiconductor technology with inventive small-scale integration.

The Redlink transmitter uses a large-current aperture (150 μm diameter) red (650 nm) eye-safe RCLED (Resonant Cavity LED) based on InGaP/InGaAlP/GaAs technology. It operates over a wide range of drive current that can be adjusted using a serial resistor to minimise current consumption for a given link distance.

The receiver uses a monolithic IC with fully integrated dual photo-diodes which act as a differential light sensor, giving enhanced immunity to EMI/EMC from the local environment making the unit ideal for use in electrically noisy applications. It has a single data output compatible with TTL/CMOS electronics.

Firecomms puts its RedLink devices through thousands of hours of testing to guarantee extended lifetimes at high temperatures.

Due to the company’s unique RCLED technology, which keeps the transmitters burning brightly after several decades, and the monolithic architecture of Firecomms fully integrated receivers, customers can design with confidence in the toughest of applications.

“Our customers’ products operate in the harshest of environments and are regularly exposed to extremes of temperature, climate and electromagnetic interference," says Hsin Chia, Firecomms CEO. “Not only must our devices operate within these harsh environments, they must operate effectively for many, many years. We are delighted to hit this milestone which is a reflection of the thousands of hours our team has invested in meeting our customers’ launch plans."

“Our new RedLink devices have been ordered by some of the world’s largest industrial conglomerates for use in applications such as electric trains, high voltage grid stations, wind and solar energy converters, mining, oil and gas exploration and motor drives," says Hugh Hennessy, Firecomms VP of Worldwide Sales and Marketing. “We are pleased with the positive response we received to bring a reliable source to market and plan to build on these successful deployments with continued innovation and expansion of our RedLink portfolio."

Firecomms utilises in-house photonics, and transmitter and receiver chips together with a world class internal production facility to guarantee the quality of its supply chain. Its vertical integration around the core technologies used in fibre optic transceivers enables Firecomms to respond flexibly to customer demands while maintaining tight control of major cost drivers.

In addition to the RedLink family of products, Firecomms produces a range of integrated 100 Mbps to 500 Mbps transceivers in its innovative OptoLock and compact LC connector systems for higher speed communications links in the medical, industrial and consumer home networking markets.



AngelTech Live III: Join us on 12 April 2021!

AngelTech Live III will be broadcast on 12 April 2021, 10am BST, rebroadcast on 14 April (10am CTT) and 16 April (10am PST) and will feature online versions of the market-leading physical events: CS International and PIC International PLUS a brand new Silicon Semiconductor International Track!

Thanks to the great diversity of the semiconductor industry, we are always chasing new markets and developing a range of exciting technologies.

2021 is no different. Over the last few months interest in deep-UV LEDs has rocketed, due to its capability to disinfect and sanitise areas and combat Covid-19. We shall consider a roadmap for this device, along with technologies for boosting its output.

We shall also look at microLEDs, a display with many wonderful attributes, identifying processes for handling the mass transfer of tiny emitters that hold the key to commercialisation of this technology.

We shall also discuss electrification of transportation, underpinned by wide bandgap power electronics and supported by blue lasers that are ideal for processing copper.

Additional areas we will cover include the development of GaN ICs, to improve the reach of power electronics; the great strides that have been made with gallium oxide; and a look at new materials, such as cubic GaN and AlScN.

Having attracted 1500 delegates over the last 2 online summits, the 3rd event promises to be even bigger and better – with 3 interactive sessions over 1 day and will once again prove to be a key event across the semiconductor and photonic integrated circuits calendar.

So make sure you sign up today and discover the latest cutting edge developments across the compound semiconductor and integrated photonics value chain.
