产品介绍

PRODUCT PRESENTATION

JFOPT QSFP-DD 400G (4x100G) 1310nm 500米 DR4 MPO8/12 光模块是一款高性能400Gb/s四通道小型可插拔双密度（QSFP-DD）光模块，专为500米中短距光通信应用优化设计。该模块将8通道50Gb/s（PAM4调制）电输入信号转换为4路并行光信号（每路100Gb/s），实现400Gb/s总速率传输；接收端则执行逆向处理，将4路100Gb/s光信号还原为8通道50Gb/s（PAM4调制）电输出。模块兼容MTP/MPO-12连接器光纤跳线，通过插座内置导向针确保精准对准，安装时严禁扭转跳线以免破坏通道对准。电气接口采用符合QSFP-DD MSA标准的边缘式连接器。紧凑型设计结合坚固的光电连接结构与数字诊断接口，使其成为高速短距数据通信应用的可靠解决方案。

绝对最大额定值

ABSOLUTE MAXIMUM RATINGS

Parameter	Symbol	Min.	Max.	Unit
Power supply voltage	VCC	-0.5	+3.6	V
Storage temperature	TC	-40	+85	℃
Relative humidity	RH	5	85	%

These values represent the damage threshold of the module.Stress in excess of any of the individual absolute maximum ratingscan cause immediate catastrophic damage to the module even if all other parameters are within recommended operating conditions.
