6.Aplication Cautions
6.1.ESD
This 100G.SHOPtransceiver is specified as ESD threshold 1kV for high speed pins and 2kV forall other electrical input pins, tested per MIL-STD-883, Method 3015.4/JESD22-A114-A (HBM). However, normalESD precautions are still required during the handling of this module. Thistransceiver is shipped in ESD protective packaging. It should be removed fromthe packaging and handled only in an ESD protected environment.
6.2. LASER SAFTY
This is aClass 1 Laser Product according to IEC 60825-1:1993:+A1:1997+A2:2001. This product complies with 21 CFR 1040.10 and1040.11 except for deviations pursuant to Laser Notice No. 50, dated (July 26,2001)
