Specifications
Cisco Compatible QDD-400G-LR8 400G QSFP-DD LR8 PAM4 1310nm 10km DOM Optical Transceiver Module (SMF, 1310nm, 10km, LC Connector, DOM)
The Cisco QDD-400G-LR8 compatible optical transceiver module is designed with duplex LC connectors, reaching a link up to 10km over a standard pair of G.652 single-mode fiber(OS2). F-tone manufactured 400GBASE-LR8 QSFP-DD transceiver module is compliant with QSFP-DD MSA, IEEE 802.3bs protocol, and 400GAUI-8/CEI-56G-VSR-PAM4 standard. Besides, 400G LR8 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.
