Juniper Compatible 400GBASE-ER8 400G QSFP-DD-ER8 PAM4 1310nm 40km DOM Optical Transceiver Module (SMF, 1310nm, 40km, LC Connector, DOM)

 

The Juniper 400GBASE-ER8 compatible optical transceiver module is designed with duplex LC connectors, reaching a link up to 40km over a standard pair of G.652 single-mode fiber(OS2). QSFPTEK manufactured 400GBASE-ER8 QSFP-DD transceiver module is compliant with IEEE 802.3cn protocol and 400GAUI-8, QSFP-DD HW Rev 5.0 and QSFP-DD CMIS Rev 4.0 standard. Besides, 400G ER8 is designed based on PAM4 (Pulse Amplitude Modulation 4-level) modulation technology, DSP (Digital Signal Processing) chip, and QSFP-DD form factor. With these features, this 400G QSFP-DD transceiver is widely applied in 400G telecom connections, DCI, metro network, long-haul, and high-performance computing networks application.
