Optical Card Front Panel Descriptions

10Gb/s OPTICAL RECEIVE-ONLY (L6)

The 10Gb/s Optical Receive-only card performs the O/E conversion for the OTS system. This Optics card works in conjunction with the Receive card which contains all of the receiver functionality and analysis capability for the OTS system.

Figure B-3 shows the Receiver Optics card front panel.

Module OK

The Module OK LED should be green while the instrument is running. On power up, the LED first lights red and then changes to green when the system has finished initializing.

NOTE: If the LED remains red after the system has finished initializing, call Tektronix for service.

Optical IN

The Optical IN port accepts the receiver’s incoming optical signal. This input signal must have a wavelength between 1290 nm and 1565 nm and must not exceed 0 dBm of power.

The LED labeled SIG PRES above the OPTICAL IN heading will turn green when the Optics card detects an incoming signal. Flashing Red indicates an optical loss of signal (LOS) condition, and flashing amber indicates an optical overload condition.

WARNING: The incoming signal must be attenuated to within specified power levels. If the signal exceeds 0 dBm, damage may occur.

Rx DATA OUT

Rx DATA OUT provides signal interconnection between the system cards.

This output must be connected to the Rx DATA IN port found on the Receive card of the OTS9100 system using the coax cable and DC block provided.

Rx DATA OUT

Rx DATA OUT is a 10Gb/s DATA Signal provided for jitter measurement. This output must be connected to the 10 Gb/s DATA IN port found on the OTS92H1 Clock Receiver Card using the coax cable provided (no DC block is necessary). Otherwise, this output is normally terminated with 50Ω.
