Connect the Instrument
In order to connect the Serial BERT let’s have a look at the Front and
the Rear Panels:
Front Panel
The Front Panel has LEDs, Data In/Out ports, and an SFP connector.

SFP
The Small Form Factor Pluggable interface (SFP) is an industry
standard daughter card used in networking devices. It interfaces a
network device with a networking cable. Typically SFP modules are
optical transceivers using multimode (850 nm), or single-mode (1310
nm, 1550nm) cabling.
An SFP loopback connector is part of the N5980A shipment delivery.
This connector is used for functional verification of the SFP port. It
has an internal loop from the SFP output to the SFP input signal.
NOTE
SFP compliant modules can be inserted into the SFP slot. While selecting
golden SFP modules observe the specifications of the selected device. Make
sure that the supported maximum PRBS length, and the maximum data rate
matches with the N5980A settings. Make sure that the wavelength of the SFP
module, and the cabling are identical, and that the optical power is within the
specified limit. To measure BER at the SFP input, select the Input “SFP
(Optical)” in the user interface.
