Cisco compatible QDD-400G-LR8-S Description
QDD-400G-LR8-S is a 400GBASE-LR8 Cisco Compatible 400G QSFP-DD (Quad Small Form-Factor Pluggable - Double Density) Transceiver designed for operation over Double Fiber Single-Mode Fiber (SMF) optical cable. On the transmission side 400GBASE-LR8 QSFP-DD converts 8x 50G 400GAUI-8 PAM4 (Pulse-Amplitude Modulation) electrical input channels (each 53.125Gbps) into 8 Single Lambda 50G PAM4 LAN-WDM optical signals which are multiplexed for transmission over SMF. Reversely the opposite is done on the receiving side. QDD-400G-LR8-S Cisco compatible has a minimum guaranteed optical budget of 6.3 dB, which in most cases is enough to reach 10 km distance over OS2 single-mode fiber. However, distance is just an indicative parameter for comfort of identification that is calculated by taking into account minimal optical budget and average attenuation of optical cabling in industry. QDD-400G-LR8-S uses top quality Octa channel EML driver and EML lasers together with an optical multiplexer (8 LAN WDM lines: 1273.54, 1277.89, 1282.26, 1286.66, 1295.56, 1300.05, 1304.58 and 1309.14 nm) transmitter and 400Gb/s PIN photodiode array receiver.
QDD-400G-LR8-S supports DDM/DOM optical diagnostics that provide real-time diagnostic information about the present operating conditions. QSFP-DD LR8 operates in Standard 0°-70°C temperature range and has a Double LC interface. 400GBASE-LR8 QSFP-DD supports up to 425 Gbps data rate and is designed for 400G Ethernet application. It is a multi-purpose module used in a number of different places of today’s networking. Consequently, most popular use cases are in Internet Service Provider (ISP), Mobile Operator and Data Center Core Networks.
400GBASE-LR8 QSFP-DD Transceiver is CE/RoHS certified and is compliant with product safety standards. QDD-400G-LR8-S is fully compliant to QSFP-DD MSA, CMIS 4.0, IEEE 802.3bs 400 Gbps specification. Consequently, compliance to above standards guarantees that module is compatible and works with majority of networking equipment, where is not implemented special algorithm for protection against third party modules. However – our technical team has accumulated deep expertise in custom-encoded firmware’s for 400GBASE LR8 QSFP-DD transceivers in order to make it work in almost any brand equipment.
