Fiber optic modules on the core switch

Small Form-factor Pluggable (SFP) modules convert electrical signals from switch circuitry to optical signals for fiber transmission. The module type must match the fiber type—this is the most critical specification preventing deployment failures. The information in this document is based on all Catalyst 9000 Series switches. This includes Doppler. Fiber connections become necessary when the distance exceeds DAC cable capabilities or connections span multiple locations. The most critical point is that fiber type. This guide provides a clear, practical comparison among the most common transceiver types - GBIC, SFP, XFP, and SFP+ - to help you make informed procurement decisions.
