FAQs

Q: Can all eight POS ports operate at line rate simultaneously?
A: The module supports eight POS interfaces; actual throughput depends on chassis fabric and configuration. Consult platform performance guides.

Q: What fiber type is required?
A: Single-mode fiber is required for the SM-IR POS interfaces.

Q: Are the GE ports configurable independently?
A: Yes. The four Gigabit Ethernet ports can be configured independently alongside the POS ports.

Q: Which platforms support this OSM?
A: It is intended for OSM-capable Cisco routing platforms. Verify compatibility in your chassis hardware documentation.
