光纤千兆以太网“光信号检测”电路硬件可靠性设计

The hardware reliable design of signal detectcircuit in the optical gigabit Ethernet adaptor

从实际工作出发,通过对原有光纤千兆以太网“光信号检测”典型电路的分析与测试,指出了原有典型电路的缺陷和不合理的设计原因。提出了“添加PECL-TTL信号转换”的改进电路的设计方案,并通过理论分析和对改进电路的测试,证明该电路设计的优越性。

The paper describes the mistake of the preliminary circuit of signal detect in the optical gigabit Ethernet adaptor through the circuit analysis and test. Then it gives an advanced circuit with a PECL-TTL transfer to correct the mistake of the preliminary circuit, and proves the circuit's advantage through the circuit analysis and the test.
