The SFP optical transceiver modules used with the POS SPAs provide the following optical fiber options:
•
•
For single-mode and multimode optical fiber connections, you can use either a duplex LC-type cable or
two simplex LC-type cables, one for transmit (TX) and one for receive (RX).
Use single-mode (for intermediate- or long-reach configurations) or multimode optical fiber cable to
connect your router to a network or to connect two OC-3c/STM-1-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 the two of them.
