Product Brief Intel Ethernet SFP28 Optics Network Connectivity Intel Ethernet SFP28 Optics Intel Ethernet SFP28 Optics deliver a proven reliable solution for deployments of high-density Ethernet Key Features Overview Hot-pluggable SFP28 optical Intel Ethernet SFP28 Optics are an excellent choice for high-speed transceivers communications equipment where extraordinary performance and Support for commercial and reliability are essential. These hot-pluggable optical modules consume extended temperature ranges low-power and are offered in the extended temperature range. RoHS 6 compliant (lead-free) When used with Intel Ethernet Network Adapters with SFP28 connectivity, these optics provide more secure connections for virtualization, flexibility for LAN and SAN networking, and consistently reliable performance. Fiber optics are more immune to harsh environmental factors. The light used for data transmission does not carry an electrical current so it cannot be impacted by electrical transmissions or radio frequency interference. Also, light has a superior signal strength that is near impervious to unwanted network taps.

The TDP transversal filter should be scaled from SR: for 100m OM3 and 0.65nm spectral bandwidth, the TDP filter should have tap separation of 21ps. This would introduce ~0.3dB eye closure penalty. 2 2
