EMCORE releases DOCSIS 3.1 laser module

EMCORE Corp. (NASDAQ: EMKR) has released the 1752A 1550-nm DOCSIS 3.1 DWDM distributed feedback (DFB) laser module for cable television (CATV) applications.

The latest model in the company’s 1550-nm QAM laser platform, the 1752A is fully compliant with the new DOCSIS 3.1 standard, supporting operational bandwidth up to 1.2 GHz, EMCORE says.

DOCSIS is the standard that facilitates the addition of high-speed data transfer over existing CATV systems. The latest version, DOCSIS 3.1, is designed to deliver several new benefits to cable companies including greater capacity and speed (see “CableLabs releases DOCSIS 3.1 chip specifications”). It allows for up to 50% more data throughput over the same spectrum to deliver up to 10 Gbps downstream and 1 to 2 Gbps upstream. DOCSIS 3.1 also decreases the cost-per-bit for data delivery by improving the efficiency of spectrum use, and it increases the energy efficiency of cable modems.

EMCORE says the 1752A laser platform has been designed specifically to support the latest DOCSIS 3.1 standard. It features 1.2 GHz operational bandwidth with low adiabatic chirp to maximize signal quality in short and long lengths of fiber. The 1752A is available in a wide range of ITU grid wavelengths and operates over an industrial temperature range. The laser's inherent linearity minimizes degradation of broadcast signals caused by quadrature amplitude modulated (QAM) channels.

"We are very pleased to introduce our first DOCSIS 3.1 laser module bringing EMCORE's leading-edge highly linear DFB laser technology to the latest standard in the CATV industry," said Jaime Reloj, vice president of business development for EMCORE. "The 1752A DOCSIS 3.1 laser is a key enabling component allowing our customers to provide fully DOCSIS 3.1 compliant systems."
