The 100GBASE-CWDM4 QSFP28 transceiver supports 100GBASE Ethernet up to 2km over single-mode fiber with duplex LC connectors. It operates on four CWDM wavelengths (1271, 1291, 1311, and 1331 nm) and complies with IEEE 802.3ba/802.3bm, 100G CWDM4 MSA, SFF-8665, SFF-8636, and ITU-T G.694.2 standards. Digital diagnostics are accessible via the I2C interface. With its hot-swappable design and reliable performance, it is ideal for data centers, high-performance computing, and enterprise core and distribution networks.
Note: The two pull-tab transceivers are shipped randomly due to different batches. And the quality is the same.
