1-Port OC-12c/STM-4 POS SPA Overview
OC-48 Module Connections
Table 3-26 describes the OC-48 specifications for use with the 2-Port and 4-Port OC-48c/STM-16 POS
SPA.
1-Port OC-12c/STM-4 POS SPA Overview
The 1-Port OC-12c/STM-4 POS SPA is a single-height SPA and installs into one SIP subslot. The 1-Port
OC-12c/STM-4 POS SPA with a small form-factor pluggable (SFP) optical transceiver module provides
SONET and SDH network connectivity with a bandwidth of 622.08 Mbps.
For more information about SPAs and their compatibility with SIPs and modular optics, see the “SIP and
SPA Compatibility” section on page 1-3.
The following sections describe the 1-Port OC-12c/STM-4 POS SPA:
• 1-Port OC-12c/STM-4 POS SPA LEDs, page 3-44
• 1-Port OC-12c/STM-4 POS SPA Interface Specifications, page 3-45
• 1-Port OC-12c/STM-4 POS SPA SFP Optical Transceiver Modules and Cables, page 3-46
1-Port OC-12c/STM-4 POS SPA LEDs
The 1-Port OC-12c/STM-4 POS SPA has three types of LEDs: two LEDs for each port on the SPA, and
one STATUS LED, as shown in Figure 3-29.
