论文摘要
我们介绍了可能用于未来粒子物理实验的四通道光学收发器模块（QTRX）的设计和测试结果。 QTRX的发射器分别为10 Gbps，基于四通道VCSEL二极管数组驱动程序（QLDD）和1 x 4 VCSEL阵列。 QTRX的接收率为2.56 Gbps或每个通道10 Gbps，基于四通道的反式阻抗和限制放大器（QTIA）和1 x 4的GAAS或INGAAS的光电二极管阵列。 QTRX为20毫米x 10 mm x 5 mm，并伴侣到MT纤维连接器。测试结果表明，QTRX以10 Gbps的每个发射器通道124兆瓦的功率在2.56 Gbps的接收器通道时，用芯片电荷泵在2.56 Gbps中实现了设计目标。 QTIA的敏感性分别为2.56 Gbps的-17 dbm和-8 dbm，分别为10 Gbps。正在设计金指界面和更紧凑的光学镜头的进一步改进。
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.
