Small Form-factor Pluggable (SFP) Optical Module Cartridges (Ethernet)

The Small Form-factor Pluggable (SFP) optical module cartridges are small, hot-pluggable devices used to provide Ethernet fiber connectivity to IP-based products from either a Densité frame or Grass Valley/Telecast standalone fiber products. Multimode fiber links can be used for links of a few hundred meters, while single-mode fiberlinks can be used at distances up to 10 kilometer and over (dependent on SFP type) without degrading signal quality.
