Emcore launches 7840 DOCSIS 3.1 low-noise CATV optical receiver and Medallion 2100 optical A/B switch

Emcore Corp of Albuquerque, NM, USA, which makes components, subsystems and systems for the fiber-optic and solar power markets, has launched the 7840 DOCSIS 3.1 low-noise CATV optical receiver and the Medallion 2100 optical A/B switch for CATV (cable television) applications. The 7840 is the latest model in Emcore’s family of high-speed optical receivers and is fully compliant with the new DOCSIS 3.1 standard, supporting operational bandwidth up to 1.2GHz. The Medallion 2100 optical A/B switch is a high-performance solution for network protection and optical redundancy in CATV/FTTx networks.

DOCSIS (Data Over Cable Service Interface Specification) is the standard that facilitates the addition of high-speed data transfer over existing CATV systems for internet access through cable TV services. DOCSIS 3.1 is the latest version being adopted by cable companies to deliver greater capacity and speed. It allows for up to 50% more data throughput over the same spectrum to deliver up to 10Gbps downstream and 1 to 2Gbps upstream. It also decreases the cost-per-bit for data delivery by improving the efficiency of spectrum use and increasing the energy efficiency of cable modems.

The 7840 DOCSIS 3.1 low-noise optical receiver is a single-mode fiber-pigtailed module featuring a low-noise, impedance-matched broadband photodiode and RF amplification. The device receives optical analog and/or digital signals for a range of video broadcast options and delivers the corresponding RF electrical output. The wide bandwidth supports the delivery of any combination of analog and digital channels up to 1.2GHz of spectrum.

The Medallion 2100 A optical A/B switch is the latest addition to the Medallion family of rack-mountable CATV optical transmission elements. It is packaged in a convenient 1 RU rack-mountable housing and provides an automatic or manual fiber-switching function to protect the network from inadvertent service outages due to up-stream optical signal degradation. Each fiber’s optical signal power level is continuously monitored, as is an adjustable optical trip threshold for each channel. Derived from the feature-rich Medallion series software and hardware base platform, the Medallion 2100 series is a low-power, cost-effective, high-performance switching solution for applications that demand reliable and rapid response to changing network conditions. Multiple standard configurations are available, including up to four independent optical switches in a single housing. Custom configurations are also available.

“The 7840 DOCSIS 3.1 CATV optical receiver can be used in both 1310nm and 1550nm applications at different points of a given network and expands our line of DOCSIS 3.1 components, which also includes the 1616A and 1752A lasers,” says Gyo Shinozaki, director of marketing for Emcore’s CATV products. “The Medallion 2100 is capable of manual switching or can be switched remotely via SNMP, adding optical protection to many system applications,” he adds.

Emcore is debuting the new 7840 DOCSIS 3.1 low-noise CATV optical receiver and demonstrating the Medallion 2100 optical A/B switch in booth #1505 at the Society of Cable Television’s (SCTE) Cable-Tec Expo at the Colorado Convention Center in Denver (23-25 September).
