The SFP optical transceiver modules used with the 1-Port and 3-Port Clear Channel OC-3 ATM SPA
provide the following optical fiber options:
•
•
For single-mode and multimode optical fiber connections, you can use either a duplex LC-type cable (see
Figure
Use a single-mode (for intermediate-reach or long-reach configurations) or multimode optical fiber
cable to connect your router to a network or to connect two 1-Port and 3-Port Clear Channel OC-3 ATM
SPA-equipped routers back-to-back.
Long-range SFP optical transceiver modules (for long-reach configurations) cannot be connected
back-to-back without using an attenuator between them.
