Installation Guide
Connect to the Network
To connect the Radiance line card to the network, insert the fiber optic
cables into the appropriate SC connectors. (See the figure below.) Be
sure the card is secured to the chassis before making network connec-
tions.
When making network connections, make sure that the transmit (TX)
optical conductor of the line card connects to the receive (RX) optical
conductor of the connected device; and be sure that the transmit (TX)
optical conductor of the device connects to the receive (RX) optical
conductor of the card.
Port 1 is the multimode (MM) interface. The OC-3/STM-1 models
support a maximum segment length of 2 km. The OC-12/STM-4 line
card supports a maximum segment length of 500 m.
Port 2 is either a singlemode (SM) or singlemode long haul (LH)
interface. The SM port supports a maximum segment length of 15 km,
and the LH port supports a maximum segment length of 40 km.
Once power is applied to the unit, correct connectivity can be verified
via the link (LK) LED.
