400G QSFP-DD ER8 VS. 400G QSFP-DD LR8 Optical Transceiver Module
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.
Low Power Consumption of the 400G QSFP-DD Optical Transceiver
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.
Application of 400G QSFP-DD ER8 Optical Modules
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.
