Usage Guidelines & Laser Safety
All installers must wear ESD anti-static wristbands while handling 10G SFP+ DWDM Transceivers to prevent static discharge damage to delicate internal optical chips and circuitry. Never directly view powered LC connector ports, as invisible infrared laser radiation can cause permanent irreversible eye damage. For testing runs shorter than 10km, install 15–20dB optical attenuators to prevent APD receiver saturation and signal distortion risks. Thoroughly wipe fiber end faces prior to connection to lower insertion loss. Maintain adequate cabinet airflow around densely populated 10G SFP+ DWDM Transceiver racks to avoid thermal buildup and wavelength drift issues. Regularly export DOM diagnostic data via Cisco CLI tools to carry out proactive network health maintenance.
When the third-party compatible 10G SFP+ DWDM 100km transceiver is used in short distance transmission, please match it with the appropriate attenuator according to the table.
