Overview
The Radiance multi-rate line card with dual small form-factor pluggable
(SFP) optics provides a simple and versatile solution for converting between
two physical data formats. Use it to connect multimode to singlemode fiber, or
singlemode fiber with different wavelengths. A wide range of interchangeable
optics ensures the multi-rate line card will accommodate current and future
system needs regardless of the network’s data rate, protocol, or wavelength.
The multi-rate card supports a frequency range from 44.7 Mbps up to 2.7 Gbps,
however, it is not a rate adapter that converts from one protocol to another. Only
one data rate is configured manually through a set of DIP switches on the card,
automatically through software auto-detection, or by changing the settings via
software commands.
The card features loopback capability for testing link integrity, Link Loss Carry
Forward and Link Loss Return for troubleshooting remote connections, and a
clock and data recovery (CDR) circuit which can be bypassed for protocol
transparency. The CDR circuitry extracts the clock and data information from
the incoming stream and clears the signal from noise or jitter, which can
significantly compromise the transmission of error-free data. The hot-swappable
multi-rate line card is designed for use with the Radiance chassis system.
Compatible with the Coarse Wavelength Division Multiplexing (CWDM)
System, the multi-rate line card supports Metrobility’s CWDM pluggable optics
with wavelengths from 1310 up to 1610 nm. When installed in a managed
Radiance R5000 Central Service Platform, the multi-rate line card provides the
interface between the service provider’s switch and a wavelength-specific
connection to the mux/demux module in an R4000 chassis. At the customer site,
the multi-rate line card converts the specific wavelength back to a standard fiber
media that matches the customer’s equipment.
When configured with an R502-M management card, software management
over the multi-rate line card allows a system administrator to monitor and
configure the unit from a PC. Console commands, Metrobility’s NetBeacon® or
WebBeacon™ management software, or any standard SNMP application can be
used for management. Through software, the multi-rate line card delivers real-
time monitoring of its internal temperature, SFP optical receive/transmit power
levels, and port link state, along with switch controls and other hardware data to
simplify troubleshooting and to ensure system stability.

Installation Guide
Follow the steps outlined in this section to install and start using the Radiance
multi-rate 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. Inspect your order carefully
for damage that may have occurred during shipment. If you discover
any shipping damage, notify your carrier and follow their instructions
for damage and claims. Save the original shipping carton if return or
storage of the unit is necessary.

When setting DIP switches*, the UP position is when the lever of the
switch is pushed away from the circuit board. The DOWN position is
when the lever of the switch is pushed toward the circuit board.
* DIP switches can also be managed via console commands or through Metrobility NetBeacon or
WebBeacon management software. Refer to the Command Line Interface Reference Guide,
NetBeacon Element Management Software Installation & User Guide or WebBeacon Management
Software Installation & User Guide for software management information.

Installation Guide
Configuring the Data Rate
SW2 is used to set the initial data rate on the R380. The data rate is
determined by the 6-bit binary code derived from the position of the
DIP switches. The table below describes the settings supported by the
multi-rate line card. 1=UP, 0=DOWN. The default setting, which
automatically detects the data rate, is highlighted in yellow.
NOTE: The initial DIP switch setting may be overridden through software.

Loopback (LBCK) Switch
Loopback is enabled independently on each port. When loopback is
enabled, the port’s transmitter is connected to its receiver, thus return-
ing incoming data back to the sender. Use LBCK1 to set loopback on
Port 1, and LBCK2 for Port 2. By default, LBCK is disabled (DOWN
position) for normal data transmission from one port to the other.
Refer to Loopback in the User Guide section for further details.
Link Loss Carry Forward (LLCF) Switch
Link Loss Carry Forward is provided as an aid in troubleshooting
remote connections. If the card loses link on one of its receivers, LLCF
will inhibit the transmission of link pulses out the opposite port. LLCF
applies to both ports.
For example, if LLCF is enabled and the multi-rate line card fails to
detect link on Port 2, the card will not transmit link pulses from Port 1.
In doing this, LLCF provides a way to extend the link loss indication
beyond a single segment.
LLCF is enabled when the LLCF switch is in the UP position. The unit
is shipped with LLCF disabled. For more information, refer to Link
Loss Carry Forward in the User Guide section.
Link Loss Return (LLR) Switch
The multi-rate line card offers Link Loss Return functionality as an
additional aid in troubleshooting remote connections. When LLR is
enabled on a port, loss of link by the port’s receiver stops its own
transmitter from sending out link pulses. LLR is enabled independently
on each port.
LLR1 enables/disables Link Loss Return on Port 1. LLR2 enables/
disables the function on Port 2 of the multi-rate line card. To enable
Link Loss Return, set the switch to the UP position. Set the switch
DOWN to disable the LLR. The unit is shipped with LLR disabled.
For more information, refer to Link Loss Return.

For more information about optics, refer to Technical Specifications.
IMPORTANT: The distances noted are for reference purposes only.
The most important factor to achieve the desired distance is the optical
power budget. Metrobility specifications indicate the typical transmit
power budget. The actual distance is a function of the fiber type and
quality, the number and quality of splices, the type and quality of
connectors, the transmission loss, and other physical characteristics.
When making fiber optic connections, make sure that the optical
transmitter (TX) on the Radiance multi-rate line card connects to the
optical receiver on the connected device, and that the optical transmitter
on the device connects to the optical receiver (RX) on the Radiance card.
Use the SD LEDs on the front panel of the card to verify correct
segment connectivity. As you insert the cable into each port, the SD
LED will be lit if the following conditions are met:
•
•
•
Power is being applied to the chassis.
All connections are secure and the cables are undamaged.
There is an active device connected to the other end of the
cable, and it is sending idle signals.
14
Installation Guide
•
The port’s receiver detects the presence of optical power and
the port’s CDR circuitry has locked onto the incoming signal.
For information on replacing the SFP transceiver, refer to Changing the
SFP Optics.
BWDM Interface
The bidirectional wavelength division multiplexed (BWDM) trans-
ceiver provides one singlemode SC connector. The O311-10-xx
supports a maximum segment length of 10 km; the O383-20-xx
supports a maximum segment length of 20 km. BWDM transceivers
must always be used in complementary pairs. That is, the O311-10-31
must be connected to the O311-10-49, and the O383-20-31 must be
connected to the O383-20-55.
The O311-10-31 transmits data at a wavelength of 1310 nm and
receives at 1490 nm. Correspondingly, the O311-10-49 transmits at
1490 nm and receives at 1310 nm. The O383-20-31 transmits at 1310
nm and receives at 1550 nm; the O383-20-55 transmits at 1550 nm and
receives at 1310 nm.

SFP Monitors
Advanced management capabilities on the Radiance multi-rate line card enables
the monitoring of the following parameters for each SFP port transceiver with
digital diagnostics.
• Optical transmit power in dBm
• Optical receive power in dBm
• SFP transceiver’s internal temperature (range is -40° to +125° C)
These monitors can assist in ensuring optimal performance and system stability.
The SFP optics also provide useful information about the port interface.
• Connector type (e.g., LC or SC)
• Wavelength in nanometers
• Link length in meters supported by the SFP transceiver
* Refer to the Command Line Interface Reference Guide, NetBeacon Element Management Software Installation &
User Guide or WebBeacon Management Software Installation & User Guide for software management information.

Loopback
The Radiance multi-rate line card features loopback testing capability to help
verify proper operation and to isolate problems within a particular segment of
the network. During loopback, the LBK LED is yellow. Loopback is enabled/
disabled in two ways: (1) setting the LBCK DIP switch(es), or (2) through
software by enabling loopback on Port 1 and/or 2. Once loopback is enabled, the
card remains in this mode until you reset the DIP switch or change the software
setting.
Normal Operation
During normal operation (loopback disabled), data from a local device enters the
local multi-rate line card through Port 1, passes through the fiber line between
the two cards, exits through Port 1 on the remote multi-rate line card, then enters
the remote device. The path is reversed for incoming data to the local device.

Link Loss Return
Both ports on the Radiance multi-rate interface line card are designed with Link
Loss Return functionality for troubleshooting remote connections. When LLR is
enabled*, the port’s transmitter shuts down if its receiver fails to detect a valid
link signal. LLR should only be enabled on one end of a cable and is typically
enabled on either the unmanaged or remote device. LLR works in conjunction
with LLCF.
The diagram below shows a typical network configuration with good link status
using two Radiance multi-rate line cards for remote connectivity. Note that LLR
and LLCF are enabled as indicated in the diagram.

If a connection breaks, the line cards will carry that link loss forward to a

Link Loss Carry Forward
The Radiance multi-rate line card incorporates LLCF to assist in troubleshooting
a remote connection. When LLCF is enabled*, the ports do not transmit a signal
until they receive a signal from the opposite port. When a lost link signal is
returned to an unmanaged line card, that lost link must then be carried forward
to a managed device (switch/hub) for trap generation.
The diagram below shows a typical network configuration with good link status
using two Radiance multi-rate line cards for remote connectivity. Note that
LLCF is enabled as indicated in the diagram.

LLCF will remain in effect for the port that is not in loopback.
*Units are shipped with the LLCF disabled (DOWN).

Coarse Wavelength Division Multiplexing (CWDM)
Using the CWDM optics, the multi-rate line cards can be integrated into a
Radiance CWDM system, in which a single fiber pair carries data bidirectionally
on multiple wavelengths. In the following examples, each colored line repre-
sents a different wavelength. The network connections are shown in gray with
the magnification circles displaying the wavelengths carried on the lines.
Connections to the end user are shown in dark gray.

Changing the SFP Optics
The multi-rate line card supports two replaceable small form-factor pluggable
(SFP) transceivers. This section explains how to remove and install the optics on
the card. Metrobility SFP transceivers are hot-swappable.
IMPORTANT: Use only Metrobility-supplied SFP transceivers with this
product. Installing any other optics may damage the unit and will void the
product’s warranty.
1. Disconnect the fiber optic network cables, if they are installed, from both
the receiver (RX) and transmitter (TX) of the SFP transceiver.
WARNING: Avoid looking into the laser or cable.
2. To remove the SFP optics from the multi-rate line card, simply pull open the
release mechanism (i.e., plastic tab, release wire, etc.) and slide the module
out of the slot, as shown below, left.

transmitter (▲). For a BWDM SFP, align it so the visible part of the circuit
board located at the back of the module is to the right.
4. Keeping the release mechanism in the closed position (bail latch should be
locked in place), slide the new SFP into the slot and push it firmly in place.
5. Remove the protective dust cover on the LC or SC connector.
6. Reconnect the network cables. Verify proper segment connectivity via the
