Port And 8-Port Fast Ethernet Spa Overview - Cisco ASR-1000-SIP10 Hardware Installation Manual

4-Port and 8-Port Fast Ethernet SPA Overview

For single-mode and multimode optical fiber connections, you can use either a duplex LC-type cable
(see
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 1-Port Channelized STM-1/OC-3 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 the two of them.
