Product Description
400G-QSFP-DD-500 is a 400GBASE-DR4 Multi-Vendor MSA Compatible QSFP-DD (Quad Small Form-Factor Pluggable – Double Density) Transceiver designed for operation over Single-Mode Fiber (SMF) optical cable. On the transmission side module converts 8x 50G 400GAUI-8 PAM4 (Pulse-Amplitude Modulation) electrical input channels (each 53.125Gbps) into 4 parallel and independent Single Lambda 100G PAM4 optical signals. Reversely the opposite is done on the receiving side, module converts 4 parallel and independent Single Lambda 100G PAM4 CWDM optical signals into 8x 50G 400GAUI-8 PAM4 electrical inputs. Module has minimum guaranteed optical budget of 3 dB, which in most cases is enough to reach 500 m distance over OS2 single-mode fiber. However, distance is just indicative parameter for comfort of identification that is calculated by taking into account minimal optical budget and average attenuation of optical cabling in industry. 400G-QSFP-DD-500 uses top quality quad channel EML driver together with 4 parallel EMLs (1310 nm) transmitter and 400Gb/s PIN photodiode array receiver. 400G-QSFP-DD-500 400GBASE-DR4 supports DDM/DOM optical diagnostics that provide real-time diagnostic information about the present operating conditions. 400G-QSFP-DD-500 operates in Standard 0°-70°C temperature range and has MTP/MPO-12 interface.
400G-QSFP-DD-500 400GBASE-DR4 QSFP-DD support up to 425 Gbps data rate and is designed for 400G Ethernet application. 400G-QSFP-DD-500 QSFP-DD Double Fiber optical transceiver is multi-purpose module used in 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.
