F i n i s a r Product Specification 2.5Gbps, 850nm VCSEL, TO-46 Package HFE4091-341 PRODUCT FEATURES 850nm multi-mode oxide isolated VCSEL Capable of modulation operation from DC to 2.5Gbps TO-46 flat window metal can component Designed for drive currents between 3- 15mA average Packaged with a back monitor Attenuated window can Unattenuated versions also available 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 high radiance VCSELs designed to convert electrical current into optical power that can be used in fiber optic communications and other applications. As the current varies above threshold, the light intensity increases proportionally. 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 HFD3081-108 and HFD3081-203 product data sheets). The low drive current requirement makes direct drive from PECL (Positive Emitter Coupled Logic) or ECL (Emitter Coupled Logic) gates possible and eases driver design. These are designed to interface with 50/125 and 62.5/125mm multi-mode fiber. They produce circularly symmetric, non-astigmatic, narrow divergence beams that, with appropriate lensing, fiber couple all of the emitter power PRODUCT SELECTION Part Number Description Attenuated TO-46 component, VCSEL with Back Monitor Photodiode, HFE4091-341 Cathode of VCSEL common with Photodiode Anode Confidential and Proprietary 2013 Finisar Corporation.
