Read this document First !DocumentNo.FTS-C006PRECAUTIONS FOR COAXIAL LASER DIODE MODULEL PRECAUTION FOR SAFETYWarning: The laser light emitted from the optical fiber end orthe edge of the receptacle is invisible and will behazardous to human eyes.Avoid looking into the optical fiberor the receptacle,when the device is operated.1) The laser diode modules are used as an optical source in the data transmissionmodules, and operated at certain bit rate in digital signal form. These modulesshould be operated after connecting with the fiber, which is used for a medium ofoptical signal.2) In viewing the laser beam, we strongly recommend to use infrared-to-visibleconverter, such as fluorescent screen or TV camera.3) Operating the laser diode module outside of its absolute maxinium ratings maycause device failure or a safety hazard.4) Do not open the housing.5) Do not pull or bend the optical fiber strongly.6) We recommend incorporating a fail-safe function in the transmitter, such as a LDdisabhng function.7) A "Warning Label", an "Aperture Label", and an "Identification and CertificationLabel", which depict the laser radiation classification, the output power, thewavelength, and the radiation direction, are attached to the individual laser diodecontainer.

Read this document First !DocumentNo.FTS-C0062, PRECAUTION FOR OPERATING1) Electrical precautionsThe device shall be handled as an electrostatic sensitive device. For the purposeof avoiding electrical static damage, lead pins are shorted by using an electricallyconductive material. In removing the device out of the container, appropriateprecautions against the damage, such as a wristband with ground cord, must betaken. The relative humidity should be maintained above 20 percents becausethat can reduce the risk of damage due to static electricity. These precautionsapply to the storage, transport, handling and testing of the device.2) Handling precautionsIncreasing junction temperature of the laser diode contained in the device maydegrade the device. For the purpose of reducing the degradation, the drivingcurrent should not go over the specified LD forward current (Ifmax).3) Mechanical precautionsThe attached optical fiber is subject to breakage if mishandled. Do not pull thedevice by the fiber. Do not coil the fiber into a loop of less than 60 millimeters indiameter.4) Thermal precautionsThe operation of the laser module at temperatures higher than specified Tc willcause a rapid degradation.The soldering time should be less than 10 seconds at temperature below 260-C.5) Operating precautionsThe output power varies in terms of the operating temperature. We recommendmaintaining the operating current and the bias current depending on theoperating temperature in order to avoid excess laser radiation.It is important to read this document carefully, since there is much important information and safetyprecaution in this document Keep this document near the products, so that it is easy to refer it whenevernecessary
