Communication Products
Product Overview
The core advantage of this optical module lies in its powerful high – speed transmission capability. It can achieve a transmission rate of up to 400Gbps. Through four independent channels, each channel transmits data at a rate of 100Gbps in parallel. This feature enables it to quickly transfer a large amount of data in an instant, significantly shortening the data processing and response time. In a data center environment, whether it is processing massive amounts of user data, conducting complex data analysis, or supporting cloud computing and artificial intelligence applications with extremely high real – time requirements, the 400G OSFP DR4 can handle them easily, ensuring the efficient flow of data.

Technical Notes
- Transmitter: Average launch power for each lane (minimum) is informative and is not the principal indicator of signal strength.
- Transmitter: Reflectance is defined looking into the transmitter.
- Receiver: Sensitivity (OMAouter), each lane maximum, is informative and is defined for a transmitter with SECQ up to 3.4 dB.
- Receiver: Measured with a conformance test signal at TP3 for BER = 2.4×10−4.
