Albis Optoelectronics announces new 28 Gbd Avalanche Photodiode (APD) with high optical damage threshold
At the virtual OFC exhibition Albis presented its new, topside illuminated 28 Gbd
demonstrated. Typical applications include 28 Gbaud PAM-4, 100GBASE-ER4 and 25G EPON. Other 28 Gbd APD solutions offered by Albis consist of bottom- illuminated chips with an integrated backside lens. The integrated backside lens focuses the incoming light beam onto the detection area, enabling an easy and efficient optical coupling. For example, APS20D1 consists of such a 28G APD chip that is flip-chip soldered onto a ceramic carrier having either a coplanar GSG or a Y-shaped contact pad layout. The large pads allow placement of multiple bonds for optimized RF performance. Albis Optoelectronics is a leading designer, developer and manufacturer of high-speed
photodiodes. For more than 15 years, the company has offered the broadest portfolio of Telcordia qualified InP and GaAs photodiodes for datacom and telecom applications in the industry. All photodiode products are manufactured in-house in Albis’ dedicated clean-room facilities. Product highlights include: PIN photodiodes for
PAM-4 and 100GBASE-ER4 applications. Side-illuminated monitor diodes and monitor diode arrays. Photodiodes with integrated lenses and optical filters. And last but not least hermetically packaged, short and long wavelength microwave photodetectors up to 30 GHz.
APD chip APD20E1. Key features of this
innovative APD are a large dynamic range and a high optical damage threshold of up to +5 dBm. The company states that 100% of devices produced are actively tested for this extended damage level, thus guaranteeing high power operation in the field. On top of that, this novel APD chip provides low noise multiplication and a high gain- bandwidth product enabling the design of high sensitivity 28G receivers. Record sensitivities of -25 dBm @ BER of 5E-5 have been
10G, 28G and 56G digital and analog receivers. High power photodiodes and packaged photodetectors. Low bias APDs for 2.5G and 10G OLT/ONUs. 28G APDs for 28 Gbaud
Fujikura’s New 90S+ Fusion Splicer
Fujikura Europe has launched its new 90S+ fusion splicer for engineers working on network upgrades and maintenance across Europe. Fujikura says the addition of the 90S+ model to its 90S series, which was first launched at the end of 2019, is in response to a doubling of internet use in some European nations in 2020. Fujikura says the thinking behind the 90S+ is that as the surge in usage puts more strain on network infrastructure, network operators have had to rely on regular maintenance and upgrades to keep people online. This means engineers’ work schedules are even busier, so a splicer which
makes the entire splicing process faster and easier was an obvious choice. With fully automated features, the 90S+ uses Active Blade Management (ABM) technology to improve the efficiency of the cleaver to reduce costs and boost productivity. It also has new Active Fusion Control Technology (AFCT), which analyses the condition of the cleave end face to perform optimal fusion control and minimise splice loss. Neil Bessant, Fujikura Europe’s Fusion Splicer divisional manager, comments, “Against previous models, the 90S+ reduces overall working time and the unique design of the 90S+ has engineers front of mind. The
easy splice positioning system makes it quicker for the user to handle the fibre, while real- time fusion control analyses the fibre’s brightness intensity during fusion – contributing to stable, reduced splice loss. The 90S+ is
one of the most reliable splicers on the market as it offers quick return on investment, is able to withstand all the elements and has a lifespan over many years – all vital for engineers looking to win upcoming installation projects.”
