F i n i s a r Product Specification 2.5Gbps 850nm VCSEL, LC TOSA HFE4190-441, HFE4191-441 PRODUCT FEATURES 850nm multi-mode oxide isolated VCSEL Extended Temperature Range Operation ( 40 to +85 deg operating range) Capable of modulation operation from DC to 2.5Gbps TO-46 tilt window metal can component, prealigned into LC Sleeve Designed for drive currents between 3-15mA average Packaged with a back monitor Attenuated window can These products are high-performance 850nm VCSELs (Vertical Cavity Surface-Emitting Lasers) designed for high-speed data communications and packaged with a custom designed power monitor diode. The power monitor diode can be used with appropriate feedback control circuitry to set a maximum power level for the VCSEL. These combined features simplify design for high data rate communication and eye safety. These products are designed to be used with inexpensive silicon or gallium arsenide detectors, but excellent performance can also be achieved with some indium gallium arsenide detectors (see HFD3180-103 and HFD3180-108 product data sheets). VCSELs produce circularly symmetric, non-astigmatic, narrow divergence beams that, with appropriate lensing, fiber couple all of the emitter power. These LC TOSA products are pre- aligned and focused fiber optic transmitters designed to interface with 50/125 and 62.5/125 m multi-mode fiber PRODUCT SELECTION Part Number Description LC TOSA with attenuated TO-46 component, VCSEL with Back Monitor HFE4190-441 Photodiode, Anode of VCSEL common with Photodiode Cathode LC TOSA with attenuated TO-46 component, VCSEL with Back Monitor HFE4191-441 Photodiode, Cathode of VCSEL common with Photodiode Anode Confidential and Proprietary 2012 Finisar Corporation.
