5.15.4 SFP Description
SFPs are integrated fiber-optic transceivers that provide high-speed serial links from a port or slot to the
network. Various latching mechanisms can be utilized on the SFP modules. There is no correlation
between the type of latch and the model type (such as SX or LX/LH) or technology type (such as Gigabit
Ethernet). See the label on the SFP for technology type and model. One type of latch available is a mylar
tab (Figure 5-17), a second type of latch available is an actuator/button (Figure 5-18), and a third type
of latch is a bail clasp (Figure 5-19).
SFP dimensions are:
Height 0.03 in. (8.5 mm)
Width 0.53 in. (13.4 mm)
Depth 2.22 in. (56.5 mm)
SFP temperature ranges for are:
COM—Commercial operating temperature range –5 degrees C to 70 degrees C (23 degrees F to
158 degrees F)
EXT—Extended operating temperature range –5 degrees C to 85 degrees C (23 degrees F to
185 degrees F)
IND—Industrial operating temperature range –40 degrees C to 85 degrees C (-40 degrees F to
185 degrees F)
