GN2108
The GN2108 is a quad channel CDR with integrated vertical cavity surface emitting laser (VCSEL) drivers.
功能
- Enables greater than 300m of reach on multi-mode OM4 fiber, and >150m reach on multi-mode OM3 fiber.
- Enables use of lower bandwidth and lower cost VCSELs for 100G-SR4 applications.
- The GN2108’s output driver compensates for the optical distortion introduced by VCSELs to enable extended reach well beyond the 100G SR4 standard, and operation with lower cost, lower bandwidth VCSELs
- Highly integrated with full suite of alarms, monitoring and test features to reduce the need for expensive MCUs, enable faster time-to-market (with reduced need for firmware design), and aid in module debug and production test.

Semtech’s Tri-Edge™ GN2255 is the industry’s first analog IC solution enabling ultra-low latency, less than 1.5W module power, and performance for up to 10km reach for 50Gbps PAM4 SFP56 optical modules. Based on the proven Tri-Edge CDR platform qualified in data center applications, the new solution delivers the cost effectiveness, small footprint, low power, ultra-low latency, and performance demanded by 5G front haul applications. The new Tri-Edge GN2255 enables 50Gbps PAM4 links that will double the bandwidth of currently deployed 25Gbps NRZ front haul links. Semtech’s introduction of the Tri-Edge 5G wireless IC will help support new 5G applications, including edge computing, enhanced mobile broadband and device streaming, and fixed wireless access (i.e., home Internet).

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。
