1. Short Sales Title (For Quotation & E-commerce Listing)

Cisco CBS350-16XTS Business 350 Series 16-Port Hybrid 10G Copper-SFP+ Fully Managed Layer 3 Switch, Global Standard Version, 16×10G Mixed Ports (8×10GBase-T + 8×10G SFP+), Dual-Stack IPv4/IPv6 Dynamic Routing, True Stackable, Fanless 1RU Rackmount Compact All-10G Fiber-Copper Aggregation Switch

2. Official Product Overview

The Cisco CBS350-16XTS is a compact all-10G hybrid copper-fiber fully managed Layer 3 switch in Cisco Business 350 global portfolio. The suffix XTS indicates hybrid 10G ports: X = 10G high-speed interfaces, T = 10GBase-T twisted-pair copper, S = dedicated 10G SFP+ fiber slots. This model has no 1G-only uplink ports (not 4G Gigabit SFP uplink variant), all ports run at 10G speed, with zero PoE support. Designed for small-to-medium enterprise high-performance workgroup aggregation, compact studio video editing racks, small multi-building fiber core, optical NAS storage and remote branch fiber monitoring environments without PoE power requirements.

Distinct from entry CBS350 Gigabit series (4G = 1G uplink models), this XTS all-10G switch eliminates Gigabit bandwidth bottlenecks, mixing low-latency 10G copper desktops/workstations and long-distance 10G fiber interconnection. It delivers full enterprise-grade managed capabilities: dynamic RIPv2 Layer 3 routing, true single-IP stacking (up to 4 CBS350 units), complete anti-spoofing security toolkit, sFlow traffic analytics and full-featured multicast control. Fanless silent passive thermal design makes it ideal for office, studio and quiet equipment room deployment.

It features 8×10GBase-T RJ45 copper access ports + 8×dedicated 10G SFP+ fiber access ports, total 16 universal 10G interfaces (no separated dedicated uplink slots; all ports support access, aggregation and stacking links). Powered by high-performance ARM processor with 512MB DRAM and 256MB flash memory, it delivers 320 Gbps non-blocking switching capacity and **238.08 Mpps wire-speed forwarding rate for 64-byte frames, paired with a 3MB shared dynamic packet buffer to eliminate congestion under 4K/8K video editing, bulk optical storage transfers and small-scale fiber surveillance streaming. Passive heat sink cooling achieves zero-noise 24/7 continuous rack operation.
