5-Port Gigabit Ethernet Spa Overview - Cisco 7600 SIP 200 - SPA Interface Processor 200 Hardware Installation Manual

2-Port Gigabit Synchronous Ethernet SPA Cables and Connectors
SFP Optics Module
The 2-Port Gigabit Synchronous Ethernet SPA uses a small form-factor pluggable (SFP) optical
transceiver module installed in each port.
Figure 3-49
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.
BITS Interface
The BITS/SSU is a bi-directional interface implemented on the 2-Gigabit Synchronous Ethernet SPA. It
relays a clock to an SSU and in return receives a clock without the wander. This interface also allows the
2-Port Gigabit Synchronous Ethernet SPA to be a system resource for older platforms that are not BITS
capable.
