Getting Started
Connect the Instrument
In order to connect the Serial BERT let’s have a look at the Front and the Rear Panels:

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 |
| 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. |
| SFP compliant modules can be inserted into the SFP slot. While selecting |
NOTE | |
| 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. |
