Cisco ONS-SE-155-1550 Compatible OC-3 SFP CWDM 1550nm 60km/100km Transceiver Module

Like-for-like substitution is the whole brief for the ONS-SE-155-1550: it matches the Cisco original at 1550nm on the CWDM grid and repeats the 60km/100km reach rating, so an OC-3 span keeps its engineered behavior after the change-out. The fiber stays single-mode (SMF), the connector stays LC/UPC, and the host keeps whatever configuration it already runs. The temperature rating is 0 to 85°C (32 to 185°F). That matters on OC-3 CWDM spans where the optic is the only element due for replacement and the rest of the plant is staying put.
