EMCORE Releases Model 3644 Mini-Tx 1.2 GHz

Emcore Corporation (NASDAQ:EMKR), a leading provider of advanced Mixed-Signal Optics products announced the release of Model 3644 Mini-Tx 1.2 Ghz, 1550 nm Linear Externally Modulated Laser.

According to the press release:

EMCORE’s new 3644 Mini-Tx is the most compact L-EML™-based transmitter released to-date. It will support links up to 100 km with all the core elements required for designers to quickly integrate the L-EML™ device technology into a variety of CATV transmitter platforms.

The L-EML™ technology breakthrough was invented, developed and is manufactured exclusively at EMCORE. It consists of a high-power, low-noise, narrow linewidth laser combined with a proprietary highly-linearized modulator in a monolithic assembly. It enables long distance optical link performance approaching traditional lithium niobate-based externally-modulated transmitters, but is much more cost-effective and far exceeds the performance of Distributed Feedback (DFB) laser-based systems.

EMCORE’s new 3644 Mini-Tx is designed to support traditional Hybrid Fiber Coax (HFC), Multi-Wavelength Node Splitting, Radio Frequency over Glass (RFoG) and RF overlay for Fiber-To-The-Premise (FTTP) applications. The platform supports RF loads of Analog, Quadrature Amplitude Modulation (QAM) and Orthogonal Frequency Division Multiplexing (OFDM) to 1218 MHz and is fully DOCSIS 3.1 compatible. The 3644 Mini-Tx achieves an exceptional Modulation Error Ratio (MER) of 44 dB across the entire operating band under full QAM load conditions. MER at the receiver is the key parameter for link performance in modern QAM based HFC networks. Additionally, there is an RF test port on-board with monitor and control via an RS-232 interface.

“Since their introduction, the acceptance of L-EML-based CATV transmitters has been tremendous,” said Grant Olecko, Senior Product Line Director at EMCORE. “Our customers asked us to expand on the form-factor options to allow them greater flexibility on how they integrate the technology into their platforms. With the new 3644 Mini-Tx we now have a wider range of form-factor options to satisfy broader customer and market requirements,” added Mr. Olecko.
