Original Cisco QSFP-4X10G-LR-S 40GBASE-PLR4 QSFP+ Transceiver Module 10km MPO 10-3118-02 The Cisco QSFP-4X10G-LR-S (Part No. 10-3118-02) is a high-performance 4x10GBASE-LR QSFP+ optical transceiver, designed for data center and enterprise networks. It operates as four independent 10GBASE-LR channels, or aggregated 40Gbps, using a single 1310 nm wavelength transmitted over four separate fibers via an MPO-12 connector. Supporting up to 10 km on standard single-mode fiber (SMF), it complies with IEEE 802.3ae and supports breakout to four independent 10G links. Factory-calibrated by Cisco, it provides reliable 40G/4x10G long-reach connectivity for campus and data center aggregation links.

Product Highlights
1.Flexible 40G to 4x10G Breakout Support for High Investment Return
- Supports seamless aggregated 40Gbps throughput or flexible breakout into four independent 10GBASE-LR links. This eliminates the need for expensive mid-span conversion equipment, maximizing port density and significantly boosting your return on investment (ROI).
2. Parallel SMF Simplicity (No CWDM4 Complexity)
- Unlike standard LR4 modules that rely on complex wavelength multiplexing, this module transmits all 4 channels at a uniform 1310 nm wavelength. Utilizing standard parallel single-mode fiber (SMF) cabling removes the hassle of wavelength management while ensuring highly reliable long-reach data transmission.
3. Industry-Standard MPO-12 Interface for Seamless Deployment
- Adopts the universal MPO-12 (MTP-12) connector interface, ensuring 100% compatibility with mainstream parallel single-mode fiber cables. This standard connectivity simplifies on-site cable routing, making high-density breakout networking incredibly easy to implement.
4. Cost-Effective 10 km 40G Solution over Existing Infrastructure
- Optimizes and leverages your existing single-mode fiber infrastructure to deliver long-reach 40G connectivity up to 10 kilometers. By eliminating expensive CWDM optical components, it provides a highly budget-friendly solution for regional data center interconnections and backbone expansions.
5. 100% Genuine Cisco Quality with Multi-Channel DOM/DDM
- As a 100% genuine Cisco S-Class module, it is fully compliant, verified, and optimized for Cisco Nexus, Catalyst, and routing platforms. Features advanced Digital Optical Monitoring (DOM) to provide real-time diagnostic tracking of transceiver temperature, supply voltage, laser bias, and optical TX/RX power per individual lane.
