1616A DOCSIS 3.1 1310nm DFB Laser Module

EMCORE, a provider of compound semiconductor-based components and subsystems for the fibre optics and space solar power markets, has expanded its recently launched DOCSIS 3.1 laser line with the release of the Model 1616A DOCSIS 3.1, 1310 nm DFB Laser Module for CATV (Cable Television) applications.

The new 1616A laser module is compliant with the new DOCSIS 3.1 standard; supporting operational bandwidth up to 1.2 GHz. 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 television services.

DOCSIS 3.1 is the latest version and is designed to deliver several new benefits to cable companies including greater capacity and speed.  It allows for up to 50 per cent 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.

The 1616A DOCSIS 3.1 laser module features EMCORE's advanced analogue chip design and operates over an industrial temperature range from -40°C-+85°C. It designed to have inherent linearity which minimises degradation of broadcast signals and is fully Telcordia qualified.

All EMCORE lasers utilizse the highly-linear, directly-modulated DFB technology which has become synonymous with high-speed photonics that drove the wide-scale deployment of fibre optics in CATV networks, satellite earth stations and mobile phone antenna sites.
