Overview For updating or expanding an existing network, Metrobility® offers the Radiance 100Mbps single interface line cards in various combinations including copper to fiber, multimode to singlemode, and fiber optic distance extension. Use the optical extender units to increase your network reach up to 100km over singlemode cables at full duplex without the need for repeaters.
Installation Guide Follow the simple steps outlined in this section to install and start using the Radiance 100Mbps single interface line card. NOTE: Electrostatic discharge precautions should be taken when handling any line card. Proper grounding is recommended (i.e., wear a wrist strap). Unpack the Line Card Your order has been provided with the safest possible packaging, but shipping damage does occasionally occur.
Set the MDI-II/MDI-X Switch (R131-1x twisted-pair ports only) To eliminate the need for crossover cables, the R131-1x line card has an MDI-II to MDI-X slide switch for its twisted-pair port. The switch is positioned directly behind its associated RJ-45 connector and allows simple setup in either straight-through (default) or crossover configura- tions.
Set the DIP Switches (R133 only) The R133 provides a set of six DIP switches located on the back of the board. These switches allow you to select from several modes of operation. To enable a function, set the switch UP (lever pushed away from the printed circuit board);...

alarm will be issued if FEF is disabled on the remote card. The FEF LED will not turn amber if FEF is disabled on the local R133 line card because it will not be able to detect the alarm. Far End Fault is enabled on Port 2 when switch FEF is ON. The unit is shipped with FEF disabled.
Remote Loopback Switch (RLBK) The remote loopback switch allows you to test the fiber connection between two Metrobility x133 units. Enabling the switch sends a loopback request to the remote fiber port. To run the remote loopback test properly, the following conditions must be met: •...
• Insert the card into a slot on the chassis making sure that the top and bottom edges of the board are aligned with the top and bottom card guides in the chassis. Do not force the card into the chassis unnecessarily.

All multimode (MM) fiber optic interfaces support a maximum segment length of 2km for remote links. The singlemode (SM) interface supports a maximum segment length of 20km, 40km, or 100km. Refer to the Network Connections list below for the maximum cable length supported by each model number. BWDM Interfaces The bidirectional wavelength division multiplexed (BWDM) port provides one singlemode SC connector that supports a maximum...

User Guide This section contains information about the operating features of the Radiance 100Mbps single interface line cards. LED Indicators The Radiance 100Mbps single interface line cards provide several LEDs for the visible verification of unit status and proper functionality. These LEDs can help with troubleshooting and overall network diagnosis and management.
Link Loss Carry Forward (LLCF) The Radiance 100Mbps single interface line cards incorporate an LLCF function for troubleshooting a remote connection. When LLCF is enabled, the ports do not transmit a link signal until they receive a link signal from the opposite port. The diagram below shows a typical network configuration with a good link status using Radiance line cards for remote connectivity.
Page 15
LLCF with Auto-Negotiation (R133 only) Important: To prevent synchronization problems, we recommend that you do not enable both LLCF and auto-negotiation at the same time on both the local and remote Radiance line cards. Disable one of the functions on either card to ensure quick link establishment.
Far End Fault (FEF—R133 Only) The R133 is designed with Far End Fault functionality to identify the loss of link in the remote unit’s fiber receiver. FEF is not applicable to the copper port. Setting FEF on the fiber optic port enables two operations: It allows the fiber transmitter to issue a FEF alarm when the fiber receiver fails to detect a valid link.
Remote Loopback (R133 Only) The Radiance R133 line card supports remote loopback testing, which is typically used to verify the integrity of the fiber link to and from a remote unit. Use this feature to remotely initiate loopback testing from a central office and to monitor the results without making a trip to the remote site.
port has reset itself and is no longer looping back the test pattern, the LB LED on the local card may briefly turn amber. For example, if the RLBK switch is ON for 40 seconds, the LB LED may briefly turn amber after 15 seconds and again after 30 seconds.
