5-Port Gigabit Ethernet SPA Overview

1-Port OC-192c/STM-64 POS/RPR VSR Optics SPA Fixed Optical Transceiver,
Connector, and Cables
The 1-Port OC-192c/STM-64 POS/RPR VSR Optics SPA uses fixed optical transceivers, one for receive
(RX) and one for transmit (TX), for SONET and SDH connection to the network. Only Very Short Reach
(VSR) optics are supported.
The 1-Port OC-192c/STM-64 POS/RPR VSR Optics SPA uses multimode MTP-type connectors:
•
Use a multimode optical fiber cable to connect your router to a network.
