Juniper OC3-4SM-I/O-B – Juniper M-series routing platforms. OC3/OC12 SONET/SDH Physical Interface Card (PIC).

The Juniper OC3-4SM-I/O-B is a Physical Interface Card (PIC) for Juniper M-series routers, installing into a compatible Flexible PIC Concentrator (FPC) slot to provide OC3/OC12 SONET/SDH WAN port capacity. PICs are the interface-level building block of Juniper’s modular M-series chassis architecture, each PIC carrying its own physical ports (in this case OC3/OC12-class fibre WAN interfaces, in ATM, Packet-over-SONET or multimode-fibre variants depending on the exact part) while relying on the parent FPC for switching-fabric connectivity. This PIC generation was widely deployed in service-provider and enterprise core/edge routers running SONET/SDH-based WAN links. Tech-Star (UK-based, shipped worldwide) supplies this Juniper PIC as used/refurbished stock for engineers maintaining legacy M-series SONET/SDH deployments. Get in touch to confirm FPC-generation compatibility for your specific chassis before ordering.
