CFP-100G-LR4 CFP-100G-LR4 Cisco 100GBASE LR4 CFP Module for ASR9000 Routers
Cisco CFP-100G-LR4 100GBASE-LR4 CFP Transceiver Module
Long-Reach 100G Connectivity for High-Performance Service Provider Networks
The Cisco CFP-100G-LR4 is a high-performance 100 Gigabit Ethernet CFP transceiver designed to deliver reliable long-distance connectivity for carrier-grade networks, enterprise backbones, and data center interconnects. Built to support the 100GBASE-LR4 standard, this module enables high-speed transmission over single-mode fiber (SMF) with a reach of up to 10 kilometers, making it ideal for metropolitan networks, campus cores, and service provider infrastructure.
Engineered for seamless integration with Cisco ASR 9000 Series routers and other compatible 100G CFP interfaces, the module converts 10 electrical lanes into 4 optical wavelengths using LAN-WDM technology to ensure efficient and high-density data transport. Its hot-swappable design allows installation or replacement without network downtime, while Digital Optical Monitoring (DOM) provides real-time diagnostics for proactive maintenance and optimal performance.
With standards-based interoperability, low latency transmission, and carrier-class reliability, the Cisco CFP-100G-LR4 transceiver is an excellent choice for organizations seeking scalable, high-bandwidth optical connectivity.

FAQs:
Q1. Which Cisco platforms support this CFP module?
This module is primarily designed for the Cisco ASR 9000 Series Routers and select Cisco Nexus 7000 Series line cards that feature native CFP slots.
Q2. What type of fiber optic cable is required for this module?
The CFP-100G-LR4 requires standard Single-Mode Fiber (SMF) with dual SC connectors. It will not work over Multimode Fiber (MMF).
Q3. Can this module interoperate with 100G QSFP28 LR4 modules?
Yes, as long as both sides use the 100GBASE-LR4 standard at the 1310nm wavelength and follow the same IEEE 802.3ba specifications, they can interoperate despite the different form factors.
Q4. Does this module support 4x25G breakout?
No, the 100GBASE-LR4 standard is designed as a single 100G link over 4 wavelengths and does not support breaking out into four separate 25G Ethernet ports.
Q5. Is a reboot required after inserting the module into an ASR 9000?
No, the module is hot-swappable. The router's IOS-XE or IOS-XR software will detect the module and initialize the interface automatically upon insertion.
