# Product Description

QDD-400G-DR4 (740-085351) is a Juniper Compatible 400GBASE-DR4 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. Juniper compatible QDD-400G-DR4 (740-085351) uses top quality quad channel EML driver together with 4 parallel EMLs (1310 nm) transmitter and 400Gb/s PIN photodiode array receiver. Compatible QDD-400G-DR4 (740-085351) supports DDM/DOM optical diagnostics that provide real-time diagnostic information about the present operating conditions. Juniper compatible QDD-400G-DR4 (740-085351) operates in Standard 0°-70°C temperature range and has MTP/MPO-12 interface.

Juniper compatible QDD-400G-DR4 (740-085351) support up to 425 Gbps data rate and is designed for 400G Ethernet application. Compatible QDD-400G-DR4 (740-085351) 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.

To ensure compatibility we have tested compatible QDD-400G-DR4 (740-085351) Transceiver in latest platforms of Juniper networking equipment, which allows us to encode transceiver EEPROM memory to be compatible and work seamlessly with Juniper platforms. Transceiver is fully compliant to QSFP-DD Multi Source Agreement (MSA), 100G Lambda MSA 400G-DR4, CMIS 4.0, IEEE 802.3bs 400 Gbps specification. Transceiver is CE/RoHS certified and is compliant with product safety standards. Feel free to Contact us – We will gladly learn about your needs and provide you with the best solution!
