Emcore Unveils 1550 Nm Directly-modulated CATV Transmitter

The GaInAsP (gallium indium arsenide phosphide) device comes in a number of fixed fibre length options up to 25 km. They are ideal for extending traditional hybrid fibre coaxial CATV systems


The Medallion 8000 is the latest addition to Emcore's 1550 nm CATV fibre optic transmitter portfolio.







It is designed for wideband applications that require both CATV and Satellite-Intermediate Frequency (SAT-IF) signals to be transmitted over fibre lengths up to 30 km.

This facilitates network designs that use a single transmitter to carry multiple signals, while lowering costs, system complexity and rack space requirements.

The Medallion 8000 supports 79-channel NTSC analogue signals and/or a combination of Quadrature Amplitude Modulation (QAM) and SAT-IF signals with a reduced number of CATV analogue channels.

It features fixed fibre length options of 0 - 10 km, 5 - 15 km, 10 - 20 km and 15 - 25 km with a maximum of 18 dBm Stimulated Brillouin Scattering (SBS) suppression, and is also available with a selectable fibre length option.

The selectable fibre length option allows the user to set the Medallion 8000 for best optimized CSO (Composite Second Order) distortions at any fibre length from 0 - 30 km in 1 km increments and has a maximum SBS suppression of 20 dBm.

The Medallion 8000 family of transmitter products is designed to support various CATV transmitter applications with a common platform. A 75 ohm CATV RF video input supports frequencies up to 1002 MHz. Design features including low chirp control, noise suppression circuitry, and patented pre-distortion technology that provides outstanding performance with Emcore'S wide range of cooled broadband directly-modulated lasers. A second 75 ohm RF input supports frequencies up to 2700 MHz for FTTP (Fibre-To-The-Premises), SAT-IF, and wireless applications.                                                                                                                     

"The new Medallion 8000 directly-modulated transmitter family builds on the strengths of our popular Medallion 6000 externally-modulated series and augments our offering for concurrent transmission of CATV and SAT-IF signals over fibre," says Jaime Reloj, Vice President of Business Development for Emcore.

"Network providers are demanding high-quality, economical delivery of video to their customers, while extending capacity and improving network management intelligence. The Medallion 8000 series transmitters are ideal for extending traditional hybrid fibre coaxial CATV systems, for RF overlay for FTTP, and for RFoG (Radio Frequency over Glass) projects in countries around the world."                                                                                                                                

Monitoring and configuration of the Medallion 8000 is supported by Emcore's latest generation Web GUI, Telnet and Simple Network Management Protocol (SNMP) software via a convenient front panel display, RS-232 port, and Ethernet port.

The feature-rich WEB GUI and latest SNMP enhancements bring a whole suite of advanced operator monitoring and configuration options to the platform, allowing for secure, simplified and future-ready functionality for the next generation of intelligent networks.

The Medallion platform is mechanically designed for flexibility and space efficiency including universal rack-mount features, modular front panel design for private label convenience, and optional front and rear port placement. Dual-redundant field-replaceable fans and power supplies are standard.



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.
