Emcore Corp of Alhambra, CA, USA – which provides indium phosphide (InP)-based optical chips, components, subsystems and systems for the broadband and specialty fiber-optics markets – has launched the Medallion 6100 series DOCSIS 3.1 1550nm externally modulated CATV transmitter, which is on display in booth #1228 at the Optical Fiber Communication Conference & Exhibition (OFC 2016) in Anaheim, CA, USA (22–24 March) and also at the China Content Broadcasting Network (CCBN) show at the China International Exhibition Center in Beijing (24–26 March).
The Medallion 6100 series represents the next level of evolution of the widely deployed Medallion 6000 series. The use of Emcore's low-noise, high-optical-output-power and narrow-optical-linewidth laser results in what is claimed to be unmatched fiber-optic transmission link performance. The transmitter supports the DOCSIS 3.1 standard of 1.2GHz in the CATV domain, and optionally up to 3.5GHz in the SAT-IF band to support new international satellite deployments. Gain tilt control is now available for both the CATV and SAT-IF band. In parallel, the Medallion 6100 offers a number of platform upgrades including the addition of a USB port for local communication, a 1000BaseT Ethernet port with an on board 4-port Ethernet switch, support for IPv4/IPv6, and SNMPv3 for advanced services.
The Medallion 6100 transmitters leverage proprietary pre-distortion circuitry to provide superior CSO (composite second order) and CTB (composite triple beat) performance allowing links up to 150km, making it suitable for extending traditional hybrid fiber coaxial CATV systems. Additionally, SBS (stimulated Brillouin scattering) suppression levels greater than 21dBm through 40km of fiber makes the Medallion 6100 series suitable for RFoG (radio frequency over glass) and RF overlay in FTTx networks in countries around the world.
"Our Medallion series of rack-mount CATV transmission equipment is ideal for network systems providers that demand the highest-quality, economical delivery of high- and ultra-high-definition video and audio, along with the highest bandwidth data transmission," says Gyo Shinozaki, VP of marketing. "The Medallion 6100 transmitters extends bandwidth for DOCSIS 3.1 compatibility, while adding advanced platform features to support cable operators as they migrate their networks to the latest technology," he adds.
At OFC and CCBN, Emcore is also showcasing its chip-level devices portfolio for telecom, GPON FTTx, datacom and wireless applications including 1310, 1490 and 1550nm laser diode chips, 10G Fabry-Perot laser chips, and 2.5G and 10G APD photodetectors. In addition, Emcore is featuring its full line of distributed feedback (DFB) butterfly lasers, DOCSIS 3.1 lasers, TO-56 lasers, low-noise optical receivers, broadband photodiodes and components for wireless and distributed antenna system (DAS) applications.
