Having a standard pair of duplex LC connectors, the transmission distance of 400G QSFP-DD ER8 optical transceiver module can be up to 40KM over parallel single-mode fiber(SMF). On the transmission side, the QSFP-DD ER8 optical transceiver converts 8*50G 400GAUI-8 PAM4 electrical input channels (53.125Gbps each) into eight single 50G PAM4 optical signals, which are multiplexed for transmitted over a single optical fiber. The 400G fiber optic transceiver designed for 400G Ethernet application, most popular use cases are in Internet Service Provider (ISP), Mobile Operator and Data Center Core Networks. 400G QSFP-DD ER8 optical transceiver offers superior performance and reliability in 400 Gigabit Ethernet applications.
400G QSFP-DD ER8 optical modules and 400G QSFP-DD LR8 optical modules have the same transmission rate, modulation technology, and use duplex LC connectors. The 400G QSFP-DD ER8 optical transceiver module complies with IEEE 802.3cn protocol, QSFP-DD MSA standard, and has digital diagnostic functions. The only difference between 400G QSFP-DD ER8 transceiver module and 400G QSFP-DD LR8 SFP optical is the transmission distance. The 400G QSFP-DD ER8 optical module can achieve a maximum transmission distance of 40km, so 400G QSFP-DD ER8 optical module is more suitable for ultra-long distance data transmission. The 400G QSFP-DD LR8 fiber optic transceiver suitable for no more 10KM transmission distance.
The optical module have 8*50G 400GAUI-8 PAM4 electrical input channels with a rate of up to 400Gbps, which complies with IEEE 802.3cn protocol, QSFP-DD MSA standard. Via LC connector, operating at 1310nm, maximum power consumption of 12W, RoHS compliant. In Single Mode Fiber (SMF), the transmission distance is up to 40KMM, which is suitable for ultra-long distance 400G and 200G/100G optical interconnections. 400G QSFP-DD ER8 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 QSFP-DD optical transceiver modules over other 400G optical modules is their lower power consumption and better thermal performance.
Data Center: For large-scale data centers, high-density and high-bandwidth are the key requirements. The 400G QSFP-DD ER8 optical modules meet the requirements of large-scale data transmission in data centers by supporting 400G transmission rate, and 40KM transmission distance are also suitable for long-distance connection within data centers.
WAN and MAN: In WAN and MAN, long-distance transmission is a common requirement. ER8 optical modules can effectively meet the demand for high-speed data transmission within or across cities through its Extended Range feature, providing a feasible solution for the construction of MANs and WANs.
QSFP-DD supports compatibility with QSFP+, QSFP28 and QSFP56, which makes upgrading to 400G networks easier. With the support of PAM4 modulation, ultra-low power 400G DCI is a more cost-effective solution.
The most widely deployed SMF 400G transceivers module are divided into two types: one is 400G-FR4/LR4 transceivers using a pair of SMFs with LC duplex connectors; the other one is 400G-DR4/XDR4/PLR4 using 4 pairs of SMF and 12C MPO transceiver connectors.
The 400G-ER8 optics module uses a single row, angled LC duplex 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.
