Juniper PTX10003 – 100GbE/400GbE High-Density Router

Guide price: Price range: £25,000.00 through £155,000.00 Ex. VAT

Product Overview

The Juniper PTX10003 is a compact, high-capacity fixed packet transport router designed for service provider, cloud and core network deployments that demand dense Ethernet connectivity and robust routing scale.

Available in 8 Tbps and 16 Tbps variants in a 3 RU chassis, it supports multi-rate 10 GbE, 40 GbE, 100 GbE, 200 GbE and 400 GbE interfaces via universal QSFP-DD and QSFP28 optics, with 100 GbE inline MACsec encryption across all ports. Powered by Junos OS Evolved, the PTX10003 combines high throughput, deep buffers and rich IP/MPLS services for peering, core and edge transport roles.

Ideal deployment / environment:
The PTX10003 is well suited to core routing, peering and edge aggregation in service provider, cloud and metro networks where high-density, high-speed Ethernet and robust transport services are critical. Its combination of 8 Tbps or 16 Tbps capacities, MACsec encryption and multi-rate port flexibility supports peering exchange points, CDN edge nodes, data-centre interconnect and IP core fabrics.

Designed for space- and power-constrained locations with strong performance and routing feature sets under Junos OS Evolved, it enables operators to deliver scalable, secure and automated IP/MPLS services at scale with efficient power and space utilisation.

Key Features

  • System throughput: available in 8 Tbps and 16 Tbps configurations.
  • Forwarding performance: up to 10.6 Bpps (16 Tbps variant) and 5.3 Bpps (8 Tbps variant).
  • Fixed port flexibility: universal QSFP-DD multi-rate support for high-density 100 GbE and 400 GbE, with breakout options to 10 GbE/40 GbE/200 GbE.
  • Form factor: 3 RU rack mount supporting field-replaceable fans and power supplies.
  • Inline MACsec: hardware-accelerated 100 GbE MACsec encryption on all supported interfaces.
  • Chassis specs: typically 88 lb (40 kg) for 8 Tbps and 110 lb (50 kg) for 16 Tbps models; ~31 inch depth.
  • Power & cooling: 3-fan (8 Tbps) or 5-fan (16 Tbps) redundant cooling, and 2×3000 W (8 Tbps) or 4×3000 W (16 Tbps) power supplies.
  • Buffering & latency: 64 Gb packet buffer (8 Tbps) / 128 Gb (16 Tbps); low-latency forwarding appropriate for core transport. Software: Junos OS Evolved with full IP/MPLS, BGP/OSPF/IS-IS, EVPN-VXLAN, segment routing and automation features.
