1-Port and 3-Port Clear Channel OC-3 ATM SPA Interface Specifications
The physical layer interface for the 1-Port and 3-Port Clear Channel OC-3 ATM SPA is Optical Carrier-3
(OC-3), and the data link layer is designed to comply with ATM specifications. The 1-Port and 3-Port
Clear Channel OC-3 ATM SPA provides up to four 155-Mbps OC-3 network interfaces for all supported
platforms.
1-Port and 3-Port Clear Channel OC-3 ATM SPA Cables and Connectors
The 1-Port and 3-Port Clear Channel OC-3 ATM SPA uses a small form-factor pluggable (SFP) optical
transceiver module installed in each port for SONET and SDH single-mode and multimode optical fiber
connection (see Figure 3-2).
Each SPA port accepts an SFP module with a duplex LC-type receptacle that allows connection to
single-mode or multimode optical fiber.
