The 400G QSFP-DD DR4 optical transceiver uses single mode fiber (SMF), the SFP transceiver can support a transmission distance of up to 500 meters. The 400G QSFP-DD transceiver module supports 4 channels, and the transmission rate of each channel is 100G, and the total transmission rate reaches 400G. The 400G QSFP-DD DR4 optical module use advanced modulation technology, and features longer transmission distance and higher bandwidth, which can meet the high-performance transmission needs of large data centers and large-scale networks, such as data centers, cloud computing networks, large enterprise networks, etc.
The 400G DR4 optical module transmits data have four channels, each channel’s transmitting data at a rate of 100Gbps, for a total transmission rate of up to 400Gbps.
And under using MPO/MTP connector single-mode fiber (SMF), the maximum transmission distance of 400G QSFP-DD DR4 optical transceiver can be reach 500 meters.
By using 100G PAM4 technology, 400G OSFP DR4 optical transceiver module can be connected to 4 pairs of 100G DR4 optical modules via 12C MTP-4*LC duplex branch fiber patch cords.
400G SFP transceiver are primarily used for interconnections within and across data centers. Within data centers, 400G QSFP-DD single mode SFP are used to connect servers and storage devices to support large-scale parallel computing and high-speed data analysis. In the data center room, the 400G fiber transceiveras are used to support high-speed data transmission over long-distance, meeting the communication needs of data centers in different geographic locations. In addition, the 400G single mode SFP can also be used in mobile base stations, passive wavelength division systems, SAN/NAS storage networks.
The 400G optical module have 4-channel full-duplex transceiver integrated module with a rate of up to 400Gbps, which complies with QSFP-DD MSA and IEEE 802.3bs 400GBASE-LR8 Ethernet standard. Via MPO interface, operating at 1310nm wavelenth, maximum power consumption of 12W, RoHS compliant. In Single Mode Fiber (SMF), the transmission distance of the 400G QSFP-DD fiber optical transceiver is up to 500m, which is suitable for short distance 400G and 200G/100G optical interconnections. 400G QSFP-DD DR4 optical module use high speed transmission technology to realize ultra-large capacity data exchange while effectively controlling cost and power consumption. In data center application scenarios, one of the major advantages of using 400G DR4 QSFP-DD optical transceiver modules over other 400G optical modules is their lower power consumption and better thermal performance.
"DR" refers to 500m reach using single-mode fiber, and "4" implies there are 4 optical channels.
The 400G-DR4 optics module uses a single row, angled (APC) MTP12 connector, FS MTP-12 APC OS2 Cable is recommended.
The 400G-DR4 optics module uses a single row, angled (APC) MTP12 connector.
While there is no direct thermal management mechanism (no integrated heat-sink), the QSFP-DD allows a maximal power consumption of 12 watts (initial spec).
A 400G QSFP-DD optical transceiver typically supports various types of interfaces, including Ethernet, InfiniBand, and Fibre Channel.
