In booth #1505 at the Society of Cable Television’s (SCTE) Cable-Tec Expo in Denver (23-25 September), Emcore Corp of Albuquerque, NM, USA, which makes compound semiconductor-based components and subsystems for the fiber-optic and space solar power markets, is hosting a demonstration of its end-to-end DOCSIS 3.1 CATV transmission link capabilities.
A DOCSIS 3.1-compliant prototype of Emcore’s Medallion 6000 Series 1550nm CATV transmitter is being featured, along with the new Medallion 2100 optical A/B switch and Medallion 7100 CATV fiber amplifier transmitting over a 40km fiber link to Emcore’s RFoG (radio frequency over glass) transceiver.
Based on Emcore’s proprietary continuous-wave laser technology, the Medallion 6000 externally modulated transmitter couples high optical output power up to 11.0dBm with low optical linewidth.
The transmitter leverages proprietary pre-distortion circuitry to provide what is claimed to be superior composite triple beat (CTB) and composite second order (CSO) performance with stimulated Brillouin scattering (SBS) suppression levels of greater than 21dBm through 40km of fiber.
The Medallion 2100 optical A/B switch is a high-performance solution for network protection and optical redundancy in CATV/FTTx networks. Its automatic switching protects the network from inadvertent service outages due to up-stream optical signal degradation.
The Medallion 7100 fiber amplifier provides stable optical outputs over a wide operating temperature range, as well as the high power and low noise figures demanded by CATV applications.
Emcore’s RFoG transceiver is passive optical network (PON)-compatible and supports 1310/1590/1610nm burst mode analog return-path, and digital or QAM upstream.
"Our end-to-end DOCSIS 3.1 demonstration at the Cable-Tec Expo will show Emcore’s capabilities to deliver the highest-quality video and audio, along with high-speed data transmission in a DOCSIS 3.1 compatible system,” says Gyo Shinozaki, director of marketing for CATV products. “Emcore’s line of CATV components and systems will support cable operators as they move to this latest DOCSIS standard for higher-speed data transfer over their existing CATV networks.”
