Alcatel 1916 Gbit/s digital Laser Module with integrated electro-absorption Modulator
Description This Alcatel 1916 contains Alcatel laser with monolithically integrated electro-absorption modulator (ILM). This chip provides much lower dispersion penalties than directly modulated DFB, without complexity LiNbO3 external modulators. Alcatel 1916 optimized ultra long-haul transmission systems using non-dispersion shifted optical fiber amplifiers. Features
Very dispersion penalty over 750km Gbit/s operation InGaAsP monolithically integrated laser modulator chip High frequency butterfly package with impedance matching bias filtering drive voltage Vpp) Internal optical isolator High power available STM-16 OC-48 ultra long-haul transmission systems Terminals submarine transmission systems
Applications
Industry-standard 14-pin butterfly package
