PTX10K-LC1105-R Use Case
Ultra-Low-Latency Secure Trading Network for Financial Institutions
In a global equities trading firm, the PTX10K-LC1105-R-PTX10K 3Tbps MACsec Line Card (30x100G/30x40G) in R mode delivers sub-100μs latency and wire-speed encryption across inter-campus links. By enabling hardware-based MACsec on each 100G port, firms achieve real-time order execution and end-to-end data integrity, reducing trade slippage by up to 15% while meeting stringent regulatory requirements.
Hyperscale Cloud On-Ramp Fabric for Multi-Tenant Data Centers
A cloud service provider deploys the PTX10K-LC1105-R-PTX10K line card to aggregate tenant traffic from 30x40G and 30x100G leaf switches into a 3Tbps spine fabric. Leveraging R mode port density and dynamic MACsec policy enforcement, the provider scales on-demand connectivity to multiple public clouds, boosting throughput by 40% and cutting port footprint by 50%, while ensuring per-tenant traffic isolation.
5G Mobile Edge and Backhaul Aggregation for Telco Carriers
A leading telecom operator uses PTX10K-LC1105-R-PTX10K line cards at regional edge POPs to aggregate 5G NSA/SA cell-site traffic over 30x100G/30x40G links. In R mode with integrated MACsec, the solution secures user plane data and supports seamless software-defined backhaul provisioning. The result is scalable 3Tbps capacity, reduced inter-site latency by 20%, and compliance with carrier privacy mandates.

Questions & Answers
What is the PTX10K-LC1105-R line card?
The PTX10K-LC1105-R is a 3 Tbps MACsec-enabled line card for the Juniper PTX10000 series, offering 30×100 GbE QSFP28 and 30×40 GbE QSFP+ ports in R (routing) mode.
What is the total forwarding capacity of the PTX10K-LC1105-R?
The card delivers a total of 3 terabits per second (Tbps) of full-duplex L2/L3 forwarding capacity with line-rate MACsec encryption.
How many and what type of interfaces does the PTX10K-LC1105-R provide?
It provides 30 QSFP28 ports supporting 100 GbE and 30 QSFP+ ports supporting 40 GbE, all on a single line card.
What is MACsec and how does the PTX10K-LC1105-R implement it?
MACsec (IEEE 802.1AE) is line-rate Layer 2 encryption. The PTX10K-LC1105-R secures data in transit on all ports without impacting forwarding performance.
What does R mode signify for the PTX10K-LC1105-R?
R mode configures the card for full Layer 3 routing, enabling advanced protocol support and enhanced packet forwarding in Junos OS.
Which PTX10000 chassis are compatible with the LC1105-R?
The LC1105-R is compatible with Juniper PTX10001, PTX10002, PTX10003 and PTX10004 chassis running Junos OS Release 19.3R3 or later.
What are the typical power and cooling requirements?
The card consumes approximately 230 W typical and 320 W maximum. It requires front-to-back airflow and meets NEBS Level 3 cooling guidelines.
What are the physical dimensions of the PTX10K-LC1105-R?
The line card measures 1.75 inches (4.45 cm) in height, 0.8 inches (2.03 cm) in width, and 16.5 inches (41.9 cm) in depth.
What environmental conditions does the LC1105-R support?

Slide the card into an available line-card slot, engage the ejector handles until they click, then power on and commit the configuration in Junos OS.
Which optical transceivers are supported on the LC1105-R?
It supports industry-standard QSFP28 modules (100 GbE SR4, LR4) and QSFP+ modules (40 GbE SR4, 40GBASE-LR4) on all ports.
Does the LC1105-R allow port breakout configurations?
No. The LC1105-R provides fixed 30×100 GbE and 30×40 GbE ports and does not support breakout or mix-and-match port speeds.
What routing protocols are supported on this line card?
In R mode, it supports OSPFv2/v3, IS-IS, BGP, MPLS LDP, RSVP-TE and segment routing under Junos OS.
Can the LC1105-R be used in a redundant configuration?
Yes. When paired with a redundant Routing Engine and power supplies, it supports stateful switchover and In-Service Software Upgrade (ISSU).
Is a software license required for MACsec on this card?
MACsec encryption is enabled by default; no separate license is required when running Junos OS Releases 19.3R3 or later.
What are typical use cases for the PTX10K-LC1105-R?
Ideal for service provider core and peering networks, data-center interconnects and high-capacity aggregation jobs with built-in MACsec.
