Optical Card Front Panel Descriptions

External Laser IN

The External Laser In provides interconnection for external fixed or tunable wavelength laser sources. The input will accept OTS Tunable lasers or customer supplied lasers that meet specifications. A polarization-maintaining (PM) jumper and an optical source with good polarization extinction are required.

As with the Optical Output, the Tx optical input connector can be configured with field interchangeable shells.

Tx Data IN

Tx Data Input provides signal interconnection between the system cards. This input must be connected to the Tx Data Out port found on the Transmit card of the OTS9100 system using the coax cable provided.

Optical IN

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