摘要:

我们介绍了一种可插拔、抗辐射的4级脉冲幅度调制(PAM4)光发射模块,名为GBT20(20 Gbps千兆比特发射器),用于粒子物理实验。GBT20具有OSFP或firefly连接器,可输入16位数据,每路速率为1.28 Gbps。GBT20驱动带有LC透镜的VCSEL芯片或VCSEL TOSA,并通过标准LC连接器与光纤接口。最小模块(包括主机连接器)尺寸为41 mm x 13 mm x 6 mm。在20.48 Gbps下,最小发射机色散眼图闭合四进制(TDECQ)约为0.7 dB。低功耗模式下的功耗约为164 mW。SEE截面低于7.5x10^(-14) cm^2。在5.4 kGy的总电离剂量(TID)后,性能没有显著退化。

英文摘要:

We present a pluggable radiation-tolerant 4-level Pulse-Amplitude-Modulation (PAM4) optical transmitter module called GBT20 (Giga-Bit Transmitter at 20 Gbps) for particle-physics experiments. GBT20 has an OSFP or firefly connector to input 16-bit data each at 1.28 Gbps. The GBT20 drives a VCSEL die with an LC lens or a VCSEL TOSA and interfaces an optical fiber with a standard LC connector. The minimum module, including the host connector, occupies 41 mm x 13 mm x 6 mm. At 20.48 Gbps, the minimum Transmitter Dispersion Eye Closure Quaternary (TDECQ) is around 0.7 dB. The power consumption is around 164 mW in the low-power mode. The SEE cross-section is below 7.5x10^(-14) cm^2. No significant performance degrades after a TID of 5.4 kGy.
