# Product Documentation
# Product Description

400G-QSFP-DD-100 is a 400GBASE-SR8 Multi-Vendor MSA Compatible QSFP-DD (Quad Small Form-Factor Pluggable – Double Density) Transceiver designed for operation over Multi-Mode Fiber (MMF) optical cable. On the transmission side module converts 8x 50G PAM4 (Pulse-Amplitude Modulation) electrical input channels (each 53.125Gbps) into 8x independent PAM4 optical signal with baud rate of 53.125 Gbps. Module has minimum guaranteed optical budget of 1.9 dB, which in most cases is enough to reach 100 m distance over OM5 multi-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-100 uses top quality VCSEL (Vertical Cavity Surface Emitting Laser) (850 nm) transmitter and 400Gb/s PIN photodiode receiver. 400G-QSFP-DD-100 400GBASE-SR8 supports DDM/DOM optical diagnostics that provide real-time diagnostic information about the present operating conditions. 400G-QSFP-DD-100 operates in Standard 0°-70°C temperature range and has MTP/MPO-16 interface.

400G-QSFP-DD-100 400GBASE-SR8 QSFP-DD support up to 425 Gbps data rate and is designed for 400G Ethernet application. 400G-QSFP-DD-100 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.

400G-QSFP-DD-100 400GBASE-SR8 QSFP-DD transceiver is CE/RoHS certified and is compliant with product safety standards. 400G-QSFP-DD-100 is fully compliant to QSFP-DD Multi Source Agreement (MSA), CMIS 4.0, IEEE 802.3bs 400 Gbps specification and 400GBASE-SR8, as defined in IEEE802.3cm and module breaks out to 8 x 50G-SR, as defined in IEEE 802.3cd. 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-SR8 QSFP-DD transceiver in order to make it work in almost any brand equipment.
