Emcore introduces second-generation 2804 fiber-optic transmitter and Medallion Series EDFAs for CATV

At the 2014 China Content Broadcasting Network (CCBN) show in Beijing, China (20-22 March), Emcore Corp of Albuquerque, NM, USA, which makes compound semiconductor-based components and subsystems for the fiber-optic and solar power markets, launched the 2804 Generation II 1310nm fiber-optic transmitter for cable television (CATV) applications. The second-generation 2804 is a fully redesigned version of the 2804 line of transmitters.

Featuring Emcore’s linear analog distributed feedback (DFB) laser, the 2804 Generation II transmitter is packaged in an economical form-factor, making it a suitable fit for small and independent operators requiring a reliable, easy-to-install high-performance solution.

The 2804 Generation II is offered in a 19 inch, 1 RU rack-mount, fully contained enclosure and features output power up to 15dBm. Several different configurations can be requested, including single or dual power supplies. Also available is a dual transmitter option, allowing users to deploy two 1310nm transmitters in the same space traditionally used for one transmitter.

“The new 2804 Generation II transmitter makes Emcore’s laser and RF technology accessible to small and independent operators,” says Jaime Reloj, VP of business development. “The innovative design offers the operator flexibility to configure their system in a variety of ways.”

Emcore expects to begin shipments of the 2804 Generation II 1310nm transmitter in second-quarter 2014.

Also at CCBN, Emcore launched the Medallion 7000 Series erbium-doped fiber amplifiers (EDFA) for cable television (CATV) applications. The new EDFAs extend Emcore’s Medallion series rack-mount CATV transmitter portfolio and feature the low noise and superior output power stability demanded by CATV operators for modern hybrid fiber coax (HFC) topologies and FTTx networks, the firm claims.

The Medallion 7000 Series EDFAs are packaged in sturdy, lightweight 1RU (7100) and 2RU (7200) housings compatible with industry-standard 19- and 23-inch rack systems. The platform provides stable optical outputs over a wide operating temperature range. Internally, Medallion EDFAs are supported with input and output isolators for enhanced system stability and performance. Optical power is continuously monitored at the input and output for automatic power control during operation.

Based on existing Medallion transmitter system design, Medallion 7000 Series EDFAs offer a rich feature-set including remote management capability through SNMP (Simple Network Management Protocol) and Telnet, plus a wide set of configuration options including port count, automatic power and gain control, connector options and integrated per channel WDM (wavelength-division multiplexing) for FTTx PON (passive optical network) or RFoG (radio frequency over glass) applications. They also support management information bases (MIBs) specified by the Society of Cable Television Engineers (SCTE) for this product class. The front panel’s VFD (vacuum fluorescent display) and controls provide the operator with the option to both monitor the status and operate the amplifier locally.

“They will provide our customers with exceptional performance characteristics to expand the capabilities of their CATV distribution networks, while providing outstanding monitor and control functionality,” claims Jaime Reloj, VP of business development. “The series offers a natural combination with Emcore’s Medallion 6000 and 8000 series externally and directly modulated CATV transmitters, enabling the complete 1550nm transmission path.”

Medallion 7000 Series EDFAs allow flexible configurations with up to 64 SC/APC output ports, high saturation output power up to 38dBm (pre-splitter), wide input dynamic range, front-panel optical input/output monitor ports, and dual redundant hot-swappable AC or DC power supplies.

Emcore expects to begin shipping the Medallion 7000 Series EDFAs in second-quarter 2014.
