Feature Description   More compact structural design: module height only 12mm Surface-mount I/O pins optimized for high-speed signal integrity Full metal casing Wide temperature range with anti-vibration design Equipped with received data signal detection function Operates solely on +3.3V single power supply LC interface type Pin and mounting dimensions fully compatible with STRATOS products

The 100G QSFP28 ER1 optical transceiver modules are designed to support 100G Ethernet, suitable for data center links up to 40km over single-mode fiber. The 100G QSFP28 ER1 module is compliant with the 100G-ER1-40 specification of the 100G Lambda MSA. The transmission end converts 4x25G NRZ electrical signals into 1x100G PAM4 optical signals. The reverse receiving side converts 1x 100G PAM4 optical signal to 4x25G NRZ electrical signal.
