Usage Guidelines & Laser Safety
This medium-reach optical transceiver is engineered for 40km mid-low band CWDM access network transmission. Never view powered optical ports directly to avoid irreversible laser eye injury. Complete ESD static protection must be worn during handling to shield internal precision laser and receiver chips. Direct short-fiber jumper connection without attenuation will trigger APD receiver saturation and permanent hardware burnout. All lab bench testing and short-distance debugging must deploy 10dB–15dB fixed optical attenuators at the Rx receiving end. Keep LC port dust caps installed during idle periods to avoid dust contamination that raises extra link loss for this mid-low band Cisco CWDM 10G SFP+ Transceiver.
