2.2.1 SFF Media Options
There is one SFF media option available on the SL240 CCPMC, short wavelength laser
(850nm) and SL100 5 volt PMC. The short wavelength version is useful for intrasystem
connections, such as connecting between cards on the same backplane. It is also suited for
short reach intersystem connections (< = 250 m).
All cards use a Duplex LC style connector available from most major cable manufacturers.
For details concerning these connectors, contact Curtiss-Wright Controls, Inc. Technical
Support.
2.2.2 SFP Media Options
The SFP transceiver modules are hot swappable, providing and efficient way to modify the
media interface configuration as needed.
Four basic SFP media options will be available for the SL240. These media options
include— a long-reach wavelength laser (1550 nm), a long wavelength laser (1300 nm), and
HSSDC2 copper. All cards use a Duplex LC style connector or HSSDC2 receptacle,
available from most major cable manufacturers. Contact Curtiss-Wright Controls for the
latest SFP options available.

Long wavelength laser interconnections are recommended for distances longer than 300
meters, as loss in multimode fiber degrades connections with short wavelength lasers past
this distance. HSSDC2 interconnections are recommended for very short distances of 30
meters or less.
The short wavelength version is useful for intrasystem connections, when connecting
between cards on the same backplane. It is also suited for short reach intersystem
connections (< 300 m).
The SFP transceivers comply with the Small Form-factor Pluggable transceiver MultiSource
Agreement (SFP MSA) to ensure compatibility between the different transceiver
manufacturers.
