Finisar Product Specification 4.25Gbps 850nm VCSEL, LC TOSA HFE4192-581, HFE4192-582 PRODUCT FEATURES * 850nm multi-mode oxide isolated VCSEL * Capable of modulation operation from DC to 5Gbps * TO-46 tilt window metal can component, prealigned into LC Sleeve * Designed for drive currents between 315mA average * Packaged with a back monitor * Attenuated window can This product is a 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. It is designed to be used with inexpensive silicon or gallium arsenide detectors, but excellent performance can also be achieved with some indium gallium arsenide detectors. 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. VCSELs produce circularly symmetric, non-astigmatic, narrow divergence beams that, with appropriate lensing, fiber couple all of the emitter power. This LC TOSA product is pre-aligned and focused fiber optic transmitters designed to interface with 50/125 and 62.5/125 m multimode fiber PRODUCT SELECTION Part Number HFE4192-581 HFE4192-582 Description LC TOSA with attenuated optics, monitor photodiode, normal polarity LC TOSA with attenuated optics, monitor photodiode, reverse polarity Confidential and Proprietary (c) 2012 Finisar Corporation.

It may either increase or decrease with temperature, depending upon relationship of TA to TO. The magnitude of the change is proportional to the threshold at TO. 4) Slope efficiency is defined as PO/IF. 5) To compute the value of Slope Efficiency at a temperature T, use the following equation: (T) (25oC)*[1+(/ T)*(T-25)] 6) Rise and fall times specifications are the 20% - 80%. Most of the devices will measure <80ps fall time. 7) To compute the value of Series Resistance at a temperature T, use the following equation: RS(T) RS(25oC)*[1+(RS/ T)*(T-25)] 8) These specifications are for the TOSA component alone. Reflections introduced by any subsequent higher level assembly may affect these values. 9) Monitor current tracking is defined as follows: Deltrk = IPD(PO = 0.75mW) / 0.75mW IPD(PO = 0.45mW) / 0.45mW 10) Relaxation Oscillation Frequency (ROF) is determined by the relationship: ROF = 1 r -1 - r tc 2 t2 Where r= IF/ITH, tc is the photon lifetime (2.5ps), and 2 is the spontaneous emission lifetime (1ns). Both tc and 2 are functions of temperature. When operating at high temperature, the r (IF/ITH) value can be significantly reduced and still maintain adequate speed performance. This is recommended in order to preserve reliability. III. 2 Typical Performance Curves Emitted Power vs. Current: Power varies approximately Threshold Current vs. Temperature: Threshold linearly with current above threshold. current varies parabolically with temperature; thus it can be nearly constant for a limited temperature range.
