1000BASE-CWDM SFP 1270nm-1610nm 20km DOM LC SMF Transceiver Module
100% compatible switch, commercial grade temperature is very accurate, it has been used for a year, the quality is still very good, I leave this comment specially, I hope it can help everyone.
I have been looking for a 1000BASE-CWDM transceiver for a long time, and found that commbroad's products are much cheaper than other companies' products, and the delivery speed is much faster, it is worth buying.
