RECAUTIONS FOR
U
SE
ESD protection is imperative. Use of ground straps, anti static mats, and other standard ESD
protective equipment is recommended when handling or testing an InGaAs PIN/APD or any other
junction photodiode.
Soldering temperature of the leads should not exceed 260℃ for more than 10 seconds.
Fiber pigtails should be handled with less than 10 N pull and with a bending radius greater than 1
inch.
