Juniper PTX10K-LC1202 4.8T Line Card | 100G, QSFP56-DD, Carrier

Scale core and edge transport with the Juniper PTX10K 4.8T line card. Designed for the Juniper PTX10000 modular router family, this optical line card is built for environments where port density, throughput, and service continuity matter. With 36 expansion slots and support for 100GBase-X, it gives network teams the capacity to build dense, high-speed forwarding planes without sacrificing chassis efficiency. The PTX10K-LC1202 supports optical fiber media and accepts QSFP56-DD and QSFP28 expansion slot types, giving operators flexibility in how they stage and connect high-speed links. That matters in carrier and large enterprise backbones where optics strategy, port mix, and upgrade planning directly affect cost per bit. The 4.8T class designation reflects the scale this module is intended to serve, making it a strong fit for backbone aggregation, peering, and transport roles. For organizations standardizing on Juniper PTX infrastructure, this line card extends the value of the chassis by adding dense, service-provider-grade capacity in a form factor built for modular growth. It is the kind of component that justifies premium routing platforms: fewer chassis, more usable throughput, and a cleaner path to scale.
