Pluggable SFP+
The SFP+ Optical Module is a 4Gb/s Short-Wavelength Transceiver designed for use in bi-
directional Fiber Optic Channel links. The modules are hot-pluggable and operate with 3.3VDC.
Each Input and Output card contains rows of SFP+ modules that serve as the fiber-optic
couplers for the fiber cables to and from the Thinklogical Tx and Rx Extenders. Individual cards
can be removed for ease of access to the SFP+ modules.
Always use dust caps to protect against damage when a fiber optic connector is not
attached to its coupling device (fiber optic equipment, bulkheads, etc.)
Figure 10a: SFP+ Module Figure 10b: It is good practice to install dust
plugs in unused SFP+s.
Each I/O card can have as many as 5 SFP+ for an HDX80 and 16 SFP+ for a HDX576 each
mounted within a grounded metal enclosure. Each SFP+ module is locked into its enclosure
with a built-in latch handle that can be opened for removal or locked for installation.

The latch handle spans the two LC ports and arrows printed on the handle indicate which port is
an INPUT ( ) and which is an OUTPUT ( ).
