Operating Basics: Functional Overview

10Gb/s Transceiver Optics

The 10Gb/s Transceiver is available with two laser options, 1310 nm and 1550 nm. The 1310 nm Optical Transceiver consists of a 1310 nm Transmitter combined with a broad band Receiver. The 1550 nm Optical Transceiver consists of a 1550 nm Transmitter combined with a broad band Receiver

Figure 2-2 shows the Transceive card with 1310 nm laser front panel.

The front panel of the Transceiver card has optical inputs and outputs, a laser lockout feature, and LED monitoring lights. Each of these items is described in more detail below.

Module OK

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

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

The Optics Transceiver card of the OTS9100 module provides all of the optical interfaces of the 10Gb/s SDH/SONET module.

Figure 2-2 shows the Optic Transceiver card front panel.

WARNING: Always avoid exposure to the laser beam. Before power is applied to the OTS9100 module be sure that all laser outputs are either covered with the screw cap provided or connected to the appropriate circuit. Keeping a laser output covered prevents dirt from contaminating the connector.

Optical OUT

The Optical Output transmits an optical data signal at a wavelength of 1310 nm or 1550 nm, with the proper installed option. The optical connector can be configured with field interchangeable shells: FC (standard), ST, or SC type. The field interchangeable shells are easily removed to allow cleaning of the optical connector interface.

The LED found under Optical OUT will light to green when the laser is active.

NOTE: If the LED lights red or fails to light at all, call Tektronix for service.
