400G QSFP-DD

2021-10-18

TEOSCO launched 400G QSFP-DD SR8, DR4, FR4 and LR4 Optical Transceivers. They comprise high-performance, hot-pluggable, small size, high-speed and low power consumption features.

The 400G QSFP-DD SR8 optical transceiver complies with IEEE 802.3bs and QSFP-DD MSA standards. It offers 8 parallel transmitter and receiver channels, each of the 8 channels operates at 850nm wavelength and supports 53.125Gbps (PAM4), transmission distances up to 100 meters. It delivers a total bandwidth of 400Gbps over OM3 multimode fiber (MMF) with an MTP/MPO-16 connector.

The 400G QSFP-DD DR4 optical transceiver is designed for 400G data center interconnects comply with QSFP-DD MSA standards. On the transmit side, the DR4 transceiver converts 8 channels of 50Gb/s (PAM4) electrical signals into 4 parallel optical channels, each running at 100Gb/s, resulting in a total optical bandwidth of 400Gbps. On the receive side, the module converts 4x100Gb/s optical signals back into 8x50Gb/s electrical outputs. It uses an MPO-12 connector for transmission over SMF and typically supports a reach of up to 500 meters at 1310nm wavelength.

The 400G QSFP-DD FR4 optical transceiver integrates 4 independent optical channels operating at 100Gbps each over CWDM4 wavelengths (1271/1291/1311/1331nm). It uses 4 EML lasers combined with a multiplexer for optical transmission and supports up to 2 km over single-mode fiber with a duplex LC connector. It is compliant with the 100G Lambda MSA specification and QSFP-DD MSA standards.

The 400G QSFP-DD LR4 optical transceiver integrates 4 independent optical channels operating at 100Gbps each over CWDM4 wavelengths (1271/1291/1311/1331nm). It uses 4 EML lasers combined with a multiplexer for optical transmission and supports up to 10 km over single-mode fiber with a duplex LC connector. It is compliant with the 100G Lambda MSA specification and QSFP-DD MSA standards.

400G optical transceivers have been widely deployed in domestic supercomputing and AI computing centers. TEOSCO 400G optical transceivers have been shipped in volume with stable performance. We welcome inquiries and look forward to providing reliable optical interconnect solutions.
