用于粒子物理实验的40 Gbps光收发器
A 40 Gbps Optical Transceiver for Particle Physics Experiments
摘要：
我们提出了一个四通道光收发模块（QTRx）的设计和测试结果可能为未来的粒子物理实验。QTRx的发射器均为10 Gbps，基于四通道VCSEL二极管阵列驱动器（QLDD）和1 x 4 VCSEL阵列。QTRx的接收器每通道数据速率为2.56 Gbps或10 Gbps，基于四通道跨阻抗和限幅放大器（QTIA）和1 x 4 GaAs或InGaAs光电二极管阵列。QTRx尺寸为20 mm x 10 mm x 5 mm，可耦合到MT光纤连接器。测试结果表明，QTRx达到了设计目标，在10 Gbps和2.56 Gbps的接收器通道与片上电荷泵的功耗分别为124 mW和120 mW的发射器通道。QTIA的灵敏度在2.56 Gbps时为-17 dBm，在10 Gbps时为-8 dBm。正在设计进一步改进的金手指接口和更紧凑的光学镜头。
英文摘要：
We present the design and the test results of a quad-channel optical transceiver module (QTRx) possibly for future particle physics experiments. The transmitters of QTRx, each at 10 Gbps, are based on a Quad-channel VCSEL Diode array Driver (QLDD) and 1 x 4 VCSEL array. The receivers of QTRx, with data rates of 2.56 Gbps or 10 Gbps per channel, are based on a Quad-channel Trans-Impedance and limiting Amplifier (QTIA) and 1 x 4 photodiode array of GaAs or InGaAs. QTRx is 20 mm x 10 mm x 5 mm and couples to an MT fiber connector. Test results indicate that QTRx achieves the design goals with a power consumption of 124 mW per transmitter channel at 10 Gbps and 120 mW at 2.56 Gbps for the receiver channel with an on-chip charge pump. The sensitivities of QTIA are -17 dBm at 2.56 Gbps and -8 dBm at 10 Gbps, respectively. Further improvements with a gold-finger interface and a more compact optical lens are being designed.
