Every WhaleyComm unit is professionally tested, reset to factory defaults, and certified by our in-house engineers — the same standard trusted by 5,000+ organisations across 25 years. Not a refurb marketplace. A certified lifecycle partner.
Tested to factory specification. Backed by 25 years of enterprise trust.
The Cisco CFP-100G-LR4 is a Refurbished 100GBASE-LR4 CFP form-factor transceiver module engineered to deliver 100 Gigabit Ethernet connectivity over single-mode fiber (SMF) infrastructure. Utilizing LR4 technology, this module transmits data across four independent wavelength lanes (using the LAN-WDM scheme), making it well-suited for long-reach data center interconnects, core switching, and high-density backbone deployments.Designed to comply with the 100GBASE-LR4 IEEE 802.3ba standard, the CFP-100G-LR4 supports link distances of up to 10 km over standard single-mode fiber — ideal for campus and enterprise environments where extended reach is a requirement without resorting to amplification or DWDM infrastructure.
As a CFP (C Form-factor Pluggable) module, this transceiver is compatible with Cisco platforms that feature CFP slots, including select Cisco ASR, Nexus, and CRS series line cards and chassis. The module is hot-swappable, simplifying maintenance and reducing downtime during upgrades or replacements.
Sourced and professionally inspected by WhaleyComm, this Refurbished unit undergoes quality verification to ensure full operational functionality — delivering enterprise-grade performance at a fraction of the cost of new hardware. It is an excellent choice for organizations looking to expand 100G capacity while managing capital expenditures. All Refurbished units from WhaleyComm are tested and shipped ready for deployment.

Ideal Use Cases
Data Center Interconnect
The CFP-100G-LR4 provides reliable 100G connectivity between data center facilities or between core switching layers separated by up to 10 km of single-mode fiber. It enables high-throughput, low-latency links essential for modern virtualized and cloud-ready data center architectures.
Enterprise Campus Backbone Upgrades
Organizations upgrading their campus backbone from 10G or 40G to 100G can leverage this transceiver for a cost-effective migration path using existing single-mode fiber plant. The long-reach capability reduces the need for additional repeater hardware across campus buildings.
Service Provider and Carrier Edge Connectivity
Service providers requiring dense 100G port capacity at the network edge or aggregation layer benefit from the CFP-100G-LR4's standard-compliant LR4 optics. Its compatibility with Cisco chassis-based platforms supports scalable, high-availability network designs.

Frequently Asked Questions
Product-specific answers about compatibility, testing, warranty, fulfilment, and purchase confidence.
The CFP-100G-LR4 requires single-mode fiber (SMF) and uses an LC Duplex connector interface. It supports link distances of up to 10 km, making it suitable for long-reach campus and data center applications.
The CFP-100G-LR4 is a Cisco-branded module designed and coded for use in Cisco platforms. Compatibility with non-Cisco equipment is not guaranteed, and some third-party platforms may require additional configuration or may not recognize the module.
Refurbished means this unit has been previously deployed and has since been professionally inspected and tested by WhaleyComm to verify full operational functionality. It is not a new unit, but it meets quality standards for enterprise deployment and is offered at a reduced price compared to new.
No — the CFP-100G-LR4 is designed exclusively for single-mode fiber (SMF) infrastructure. For multimode fiber applications, a different transceiver standard such as 100GBASE-SR10 or 100GBASE-SR4 would be required.
