GN25L98
GN25L98 is a low-cost combined burst mode laser driver and limiting amplifier designed for gigabit passive optical network (GPON) optical networking unit (ONU) applications. GN25L98 features automatic extinction ratio control for reliable operation of the laser over all conditions. A high accuracy auto-ranging A/D converter and on-chip temperature sensor give precise diagnostic reporting. A low-cost integrated avalanche photodiode (APD) controller enables a complete receive solution.
GN25L98 的应用包括模块和 BOSA-on-board ONU。GN25L98 与 GN25L53 跨阻放大器 (TIA) 构成低成本芯片组。

Power, latency and cost. The three horsemen of Artificial intelligence (AI) and Machine Learning (ML) data center interconnects. Each new generation of interconnect drives a lower mW/Gbps and dollar/Gbps. Power consumption is not just about data center operating expenses. It is also about sustainability.

在 2018 年进行了大量演示和 alpha 模块测试之后，双密度版本的四通道小型可插拔 (QFSP) 多源协议 (MSA) 模块标准有望成为新线卡的规则。QSFP-DD 热潮的隐含意义不是模块本身的物理特性，而是转向先进信令方法的趋势。十年前，QSFP28 的问世预示着使用 NRZ 信令的 25Gbps 电通道即将占据主导地位。如今，QSFP-DD 及其更庞大的表亲 —— 八进制 SFP 或 OSFP ，都使用 PAM4 信令。其用得最多的是 50Gbps 通道。但 QSFP-DD 足够灵活，可以在各种实施中使用八通道接口：25G x 8 用于 200Gbit 以太网，50G x 8 用于 400Gbit 以太网，可能还有一些早期的 100G x 8 用于预标准 800Gbit 以太网。

The 44th installment of the European Conference on Optical Communication (ECOC) Exhibition recently concluded in Rome, Italy. At the conference, Semtech® featured several products for the critical hyper-scale data center and 5G wireless markets. The technologies demonstrated by Semtech from its diverse portfolio of Optical solutions include the ClearEdge® CDR platform for low-cost 25G SFP28 modules that will be an essential component of the 5G infrastructure build out. Additionally, Semtech demonstrated its new line of Tri-Edge CDRs and FiberEdge™ linear Physical Media Dependent (PMD) devices that will help drive current Cloud data center build outs.
