1-Port Channelized STM-16/OC-48 SPA Overview
Figure 7: SFP Optics Module
The SFP optical transceiver modules used with the SPAs provide the following optical fiber options:
• Multimode—622.08-Mbps, OC-12 optical fiber (SONET STS-12c)
Use a multimode optical fiber that has a core/cladding diameter of 62.5/125 microns.
• Single-mode—622.08-Mbps, OC-12 optical fiber (SONET STS-12c)
Use a single-mode optical fiber that has a modal-field diameter of 8.7 ±0.5 microns. (Nominal diameter is
approximately 10/125 microns.)
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 2-Port Channelized OC-12/DS0 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.
