Laser/Led Safety - Cisco ASR 9000 Series Installation Manual

Installing Modular Line Cards and Modular Port Adapters

Laser/LED Safety

The single-mode transmitter in the module uses a small laser to transmit the light signal to the network
ring. Keep the transmit port covered whenever a cable is not connected to it. Although multimode
transceivers typically use LEDs for transmission, it is good practice to keep open ports covered and avoid
staring into open ports or apertures. The single-mode aperture port contains a laser warning label, as
shown in
