The 25G DWDM SFP28 optical module is designed specifically for high-speed communication equipment serving distances from 24.33Gb/s to 25.78Gb/s between 10km (PIN) and 15km (APD), with low cost, excellent performance, and reliability. Basic. Low power consumption, powered by 3.3V DC power supply and provided within the industrial temperature range. They comply with the SFP28 MSA, SFF-8431, and SFF-8432 standards.
The optical components with low jitter and low bit error rate have D18~D61 EML laser emitters and PIN/APD receivers. It utilizes internal clocks and data recovery (CDR) units on the transmitter and receiver chains to achieve low jitter compliance. The differential AC coupling Tx and Rx data interfaces are compatible with CML. This device complies with Class I laser safety standards.
