1-Port Clear Channel OC-12 ATM SPA Interface Specifications

The physical layer interface for the 1-Port Clear Channel OC-12 ATM SPA is Optical Carrier-12
(OC-12), and the 1-Port Clear Channel OC-12 ATM SPA is designed to comply with ATM specifications.
The 1-Port Clear Channel OC-12 ATM SPA provides one 622.08 Mbps OC-12 network interface for all
supported platforms.
The single SPA port accepts an SFP module with a duplex LC-type receptacle that allows connection to
single-mode or multimode optical fiber.

1-Port Clear Channel OC-12 ATM SPA Cables and Connectors

The 1-Port Clear Channel OC-12 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
The 1-Port Clear Channel OC-12 ATM SPA supports the following types of optical transceiver modules:
Multimode (MM) SFP module—SFP-OC12-MM
Short-reach (SR) SFP module—SFP-OC12-SR
Intermediate-reach (IR) SFP module (15 km)—SFP-OC12-IR1
Long-reach (LR) SFP module (40 km)—SFP-OC12-LR1
Long-reach (LR) SFP module (80 km)—SFP-OC12-LR2
The SR, IR, and LR1 transceivers provide a full-duplex 622.08-Mbps, laser-based SONET/SDH-
compliant interface with an average wavelength of 1310 nm. The LR2 transceivers provide a full-duplex,
622.08-Mbps, laser-based SONET/SDH-compliant interface with an average wavelength of 1530 nm.
The multimode transceiver provides a full-duplex, 622.08-Mbps, LED-based SONET/SDH-compliant
interface with an average wavelength of 1325 nm.
