# QSFP56-200G-FR4S 200G QSFP56 FR4 PAM4 CWDM4 2km LC SMF FEC Optical Transceiver Module

### 200G QSFP56 FR4 PAM4 CWDM4 lanes MUX/DEMUX Design 2km Optical Transceiver Module (1271nm 1291nm 1311nm 1331nm LC SMF 2km with FEC DDM)

  
200G InfiniBand HDR QSFP56 FR4 Transceiver Module is designed for 200GBASE Ethernet link up to 2km over single-mode fiber (SMF) using a wavelength of 1271nm to 1331nm with duplex LC connectors. The module supports four electrical interface channels and operates in 50G PAM4 coding mode, resulting in 200G (4x50G) data rates. It is compliant with IEEE 802.3cd, IEEE 802.3bs, QSFP56 MSA, SFF-8665, SFF-8024 and SFF-8679 standards. The built-in digital diagnostic monitoring (DDM) allows access to real-time operating parameters. It is suitable for 200G Ethernet, InfiniBand HDR, data centers, and cloud networks.
