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.
Enterprise-grade 10GBASE-LR performance at a fraction of OEM cost. Backed by 25 years of enterprise trust.
The WCI SFP-10G-LR-WC-CS is a new, MSA-compliant 10GBASE-LR SFP+ optical transceiver built for long-reach 10-Gigabit Ethernet links up to 10 km over single-mode fiber. Manufactured through Whaley Communications' Network Distributors partnership and built to Tier-1 standards, this module delivers the optical performance and reliability of OEM-branded LR optics at a significantly lower cost. Every unit ships fully tested and DOM-enabled, backed by WhaleyComm's ISO 9001-certified quality assurance program.Operating at a 1310nm wavelength and utilizing a duplex LC connector, the SFP-10G-LR-WC-CS is fully compliant with IEEE 802.3ae and SFF-8431 MSA standards. Digital Optical Monitoring provides real-time visibility into transmit and receive power, temperature, and voltage, enabling proactive link health management. The hot-swappable SFP+ form factor allows for zero-downtime installation across a broad range of enterprise switches, routers, and network appliances.
For network teams looking to scale 10G fiber infrastructure without OEM price premiums, the WCI SFP-10G-LR-WC-CS delivers identical performance at a fraction of the cost. Whaley Communications has supplied optics and enterprise hardware to 5,000+ customers over 25+ years — every module is tested per-order for your specific target platform before it ships.

Ideal Use Cases
Data Center Leaf/Spine Uplinks
Provides reliable 10G long-reach connectivity between leaf and spine switches in modern data center architectures, supporting low-latency, high-throughput traffic flows.
Enterprise Core and Distribution Layers
Ideal for interconnecting core and distribution switches across enterprise campus environments where single-mode fiber runs exceed the reach of SR optics.
Campus Backbone Links
Supports 10G backbone connectivity across large campuses where inter-building fiber runs require the 10 km reach of an LR transceiver.
Long-Reach Server and Storage Connectivity
Enables 10G connectivity between servers or storage arrays and network equipment located in physically separate data halls or facilities.
10G WAN and MAN Point-to-Point Links
Suitable for metro-area or point-to-point WAN links over dark or leased single-mode fiber infrastructure where cost-effective LR optics are required.

Product-specific answers about compatibility, testing, warranty, fulfilment, and purchase confidence.
The module is engineered for broad multi-vendor interoperability and is compatible with MSA-compliant switches and routers from Cisco, Arista, Juniper, Aruba, HPE, Dell Networking, Extreme Networks, Supermicro, MikroTik, Ubiquiti, and other MSA-compliant platforms. Compatibility may vary by software version, and every unit is tested per-order for your requested platform before shipment.
Yes. The SFP-10G-LR-WC-CS includes full DOM/DDM support, providing real-time diagnostics for transmit and receive optical power, temperature, supply voltage, and bias current. This allows network engineers to proactively monitor link health without interrupting traffic.
The SFP-10G-LR-WC-CS requires single-mode fiber and uses a duplex LC connector. It supports links up to 10 km at a 1310nm wavelength and is not compatible with multi-mode fiber infrastructure.
Yes. Every WhaleyComm unit ships with a Lifetime Warranty. If it fails under normal operating conditions at any point, we replace it at no cost — no time limits, no questions asked.
Every unit goes through our ISO 9001-certified testing process: full power-on diagnostics, port-by-port functionality testing, firmware verification, factory reset, and final inspection. A Certificate of Testing ships with every unit.
