The Cisco industry-standard Small Form-Factor Pluggable Interface Converter (SFP) for packet-over-SONET/SDH (POS), optical networking, and ATM applications are hot-swappable optical interfaces that plug into a variety of ports on Cisco router interfaces. These SFP optics support OC-3, OC-12, and OC-48 data rates for multimode, short-reach, intermediate-reach, and long-reach applications.
