Emcore to show DOCSIS 3.1 optical link at OFC 2015

Optical components and subsystems vendor Emcore plans to host a demonstration of its end-to-end DOCSIS 3.1 cable television (CATV) optical transmission link capabilities at booth #608 during OFC 2015, 24-26 March in Los Angeles, California.

A DOCSIS 3.1 compliant prototype of Emcore’s Medallion 6000 Series 1550 nm CATV transmitter will be featured in the demonstration, along with the new Medallion 2100 optical A/B switch and Medallion 7100 CATV fibre amplifier transmitting over a 40-km fibre link to Emcore’s RFoG (radio frequency over glass) transceiver.

"Our end-to-end DOCSIS 3.1 demonstration at the OFC 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," said Gyo Shinozaki, director of marketing for Emcore’s 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."

The Medallion 6000 externally-modulated transmitter, based on Emcore’s proprietary continuous-wave laser technology, couples high optical output power of up to 11.0 dBm with low optical linewidth resulting in unmatched performance, the company claims. The transmitter uses proprietary pre-distortion circuitry to provide superior performance against composite triple beat (CTB) and composite second-order beat (CSO) with side-band suppression levels of greater than 21 dBm through 40km of fibre.

The Medallion 2100 optical A/B switch is a high-performance product for network protection and optical redundancy in CATV/FTTx networks. Its automatic switching protects the network from inadvertent service outages due to upstream optical signal degradation.

Emcore’s Medallion 7100 fibre amplifier provides very stable optical outputs over a wide operating temperature range, as well as the exceptionally high power and low noise figures demanded by CATV applications. Emcore’s RFoG transceiver is passive optical network (PON) compatible and supports 1310/1590/1610 nm burst-mode analogue return path, and digital or QAM upstream.
