12 Installation Guide
The R752-11 redundant interface line card provides two additional RJ-
45 jacks for the PRIMARY and SECONDARY port connections. Both
ports support a maximum segment length of 100 meters over Category
5e twisted-pair cables.

Fiber Optic Interface
The R752-1S and R752-SS redundant interface line cards provide two
or three fiber optic ports, respectively. Each fiber port provides a set of
LC connectors. For maximum flexibility in designing or expanding
your network, these fiber ports support any combination of the follow-
ing Metrobility small form-factor pluggable (SFP) transceivers. The
maximum distance and fiber type supported by each port is as follows:
Model # Distance Fiber Type
O211-M5 ....................... 550 m .................... multimode
O211-10 ........................ 10 km ....................singlemode
O211-25 ........................ 25 km ....................singlemode
O211-40 ........................ 40 km ....................singlemode
O211-70 ........................ 70 km ....................singlemode
O211-1A...................... 100 km .................... singlemode
O411-80-xx ................... 80 km ....................singlemode (CWDM)
IMPORTANT: The Radiance 1000Mbps redundant interface line card
is designed to operate using only the Metrobility SFP transceivers
listed above. Installing unspecified parts may damage the product and
will void the unit’s warranty.
When making fiber optic connections, make sure that the transmit (TX)
optical conductor of the Radiance redundant line card connects to the
receive (RX) optical conductor of the connected device, and that the
