Edge-mounted SMA connectors are
provided for data inputs and data
outputs. Standard 2 mm sockets are
included for easy connection to DC
power supplies. A sliding switch is
provided for selecting the transmitter
disable function. Gold contact pin
sockets are used to allow inter-
changeability between transceiver
modules while assuring good con-
nection integrity. Ground tab con-
nection holes are provided on the
test fixture for grounding the SFF

transceiver body. Grounding the
transceiver body is recommended
for optimum performance and EMI
compliance. Generous grounding is
provided around the transceiver
footprint using plated through holes.
Figure 4 shows the circuit schematic
for the test fixture. Separate power
supplies are provided to the trans-
mitter and receiver sections, and
the recommended filtering arrange-
ments are also shown.

The signal detect (SD) function is
provided for the user. No termina-

TTL levels.
The test fixture requires +3.3 V supply

ter enable/disable switch needs to
be in position 2 for normal operation
and position 1 disables optical data
transmission. The test fixture is rated
for repeated temperature evaluation
from 0° C to +70° C.
