PRODUCT OVERVIEW
2.3.5 SFP Media Options
The physical media interface of the GT200 design uses SFP transceiver modules. These
modules are hot swappable, providing an efficient way to modify the media interface
configuration as needed.
Two basic SFP media options are available for the GT200. These media options are a
long wavelength laser (1300 nm) and short wavelength laser (850 nm). All cards use a
Duplex LC style connector available from most major cable manufacturers.

Long wavelength laser interconnections are recommended for distances longer than 250
meters, as loss in multimode fiber degrades connections with short wavelength lasers past
this distance.
The short wavelength version is useful for intrasystem connections, where you are
connecting between cards on the same backplane. It is also suited for short reach
intersystem connections (< 250 m).
The SFP transceivers comply with the Small Form-factor Pluggable transceiver
MultiSource Agreement (SFP MSA) to ensure compatibility between the different
transceiver manufacturers.
