EMCORE Corp. (NASDAQ: EMKR) has introduced the Medallion 7000 Series erbium-doped fiber amplifiers (EDFAs) for cable television (CATV) applications. These new EDFAs extend EMCORE's Medallion series rack-mount CATV transmitter portfolio; the company says the EDFAs feature the exceptionally low noise and superior output power stability demanded by CATV operators for modern hybrid fiber/coax (HFC) topologies and fiber-to-the-x (FTTx) networks.
Medallion 7000 Series EDFAs are packaged in a sturdy, lightweight 1RU (7100) and 2RU (7200) housings compatible with industry-standard 19- and 23-inch rack systems. EMCORE says the platform provides very 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 feature set that includes remote management capability through SNMP (Simple Network Management Protocol) and Telnet, plus configuration options including port count, automatic power and gain control, connector options, and integrated per channel WDM for passive optical network (PON) or radio-frequency-over-glass (RFoG) 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 vacuum fluorescent display and controls provide the operator with the option to both monitor the status and operate the amplifier locally.
"We are very excited about the new Medallion 7000 Series EDFAs because 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," said Jaime Reloj, vice president of business development for EMCORE. "The series offers a natural combination with EMCORE's Medallion 6000 and 8000 series externally- and directly-modulated CATV transmitters enabling the complete 1550-nm transmission path."
Medallion 7000 Series EDFAs offer up to 64 SC/APC output ports, high saturation output power up to 38 dBm (pre-splitter), wide input dynamic range, front panel optical input/output monitor ports, and dual redundant hot-swappable AC or DC power supplies, the company adds.
EMCORE expects to begin shipping the Medallion 7000 Series EDFAs beginning in the second quarter of 2014.
