LEDs

The AT-LX3800U provides two groups of LEDs, one group for each line card and one group for the system.

Line Card LEDs Each line card has six LEDs, as shown in Figure 6.

Figure 6. Line Card LEDs

The line card LEDs include a RDY (Ready) LED that provides information about the overall operation of the line card, and two groups marked TRIB and LINE. The TRIB LEDs provide information about the tributary side of the line card (the operation of the SFP), and the LINE LEDs display information about the line side of the line card (the operation of the RX and TX Wavelength Division Multiplexing (WDM) ports).

124

The LEDs are described in the following tables:

 The RDY LED is described in Table 2.  The tributary side TX and RX LEDs are described in Table 3 on

page 24.

 The line side TX and RX LEDs are described in Table 4 on page 25.  The line side Sync LED is described in Table 5 on page 27.

Table 2 describes the RDY LED on the tributary side.

2. Measure the optical power coming into the RX port using a passthrough optical power monitor.

Page 59

AT-LX3800U Multi-Service Transport System Installation and Maintenance Guide

Note

A pass-through optical power monitor is required because when the fiber optic cable is removed from the RX or TX port, the Open Fiber Control algorithm is activated. This results in a significant reduction in optical power compared to the closed loop actual optical power value.

If the received optical power is greater than -7 dBm per channel, additional attenuation is required. RX values greater than -7 dBm per channel could potentially damage the optical receiver if applied for more than 60 seconds.

Note

When you add attenuation to the system, ensure that the attenuated value does not drop below the receiver’s sensitivity values. Refer to “Optical Specifications” on page 76 for more information.

3. Remove the pass-through optical power monitor from the RX port.

Cleaning Fiber Optic Connectors

The fiber optic connector consists of a fiber optic plug and its adapter. The end of the fiber optic cable is held in the core of the ferrule in the plug. Light signals are transmitted through the core of the fiber. Even minor smudges or dirt on the end face of the fiber, completely invisible to the naked eye, can disrupt light transmission and lead to failure of the component or of the entire system. Therefore, it is of utmost importance to clean all fiber optic connectors before use.

Figure 48 shows the ferrule in an SC connector.
