1.[100G DR1 SINGLE-LAMBDA LINK] QSFP28 DR1 transceiver uses 1311nm PAM4 over duplex LC single-mode fiber and supports transmission up to 500m with FEC enabled. Includes digital diagnostic monitoring.

2.[WIDE COMPATIBILITY] Compatible with Cisco QSFP-100G-DR-S and other open network platforms that accept standard 100G QSFP28 DR1 modules. 

3.[PAM4 & FEC ARCHITECTURE] An integrated DSP converts the host-side 4x25Gbps NRZ electrical signals to a single 50Gbaud PAM4 optical signal and includes retiming and FEC functions. FEC must be enabled to support the maximum 500m link distance.

4.[DIGITAL MONITORING] SFF-8636 DMI provides real-time access to module temperature, supply voltage, laser bias current, transmitted optical power and received optical power.

5.[100G STANDARDS & POWER] Maximum power consumption is 4.5W with a single 3.3V supply and 0°C to 70°C operating case temperature. Compliant with QSFP28 MSA, IEEE 802.3cu, 100GE DR1 specifications and RoHS 2.
