Cisco Genuine QSFP-100G-LR4-S 100G QSFP28 LR4 10-3146-01 Transceiver 10km The Cisco QSFP-100G-LR4-S (Part No. 10-3146-01) is a high-performance 100GBASE-LR4 QSFP28 optical transceiver, designed for enterprise and service provider networks. It adopts LAN-WDM technology with four independent 25.78125 Gbps lanes at 1295/1300/1305/1310 nm wavelengths, multiplexed onto a single pair of single-mode fibers using NRZ modulation. Equipped with a standard LC duplex connector, it supports 100Gbps transmission up to 10 km over standard single-mode fiber (SMF). Factory-calibrated by Cisco, it provides reliable 100G long-reach connectivity for data center interconnections and enterprise backbone links.

Typical Applications
Data Center Interconnect (DCI) up to 10 km
- Engineered for high-capacity backbone links connecting geographically separated data center halls or distributed cloud facilities within a 10 km range.
Enterprise Campus and Core Backbone 100G Long-Reach Links
- Ideal for establishing long-distance core-to-distribution layers across massive corporate backbones, government networks, and university campuses.
Service Provider 100G Aggregation and Transport Networks
- Perfect for telecom service providers deploying high-density traffic aggregation, metro core transport loops, and robust Optical Transport Network (OTN) paths.
Cisco QSFP28 Port Switch/Router 100G Uplink Ports
- Seamlessly delivers native, carrier-grade 100G uplink capabilities for Cisco Nexus, Catalyst, and premium router platforms equipped with standard QSFP28 slots.
High-Capacity Regional and Metro Network Expansion Projects
- Provides an ultra-efficient, unamplified scaling solution to instantly eliminate transmission bottlenecks over existing regional single-mode fiber infrastructure.
Product Highlights
10km Long-Reach 100G Solution
- Engineered for extended-reach infrastructure, delivering a rock-solid 100Gbps connection up to 10 km over standard single-mode fiber (SMF). It represents the definitive choice for high-capacity metro aggregation and enterprise backbone networks where long-distance data integrity is critical.
LAN-WDM Technology for Maximum Fiber Efficiency
- Leverages the tightly spaced LAN-WDM wavelength grid to multiplex four independent 25Gbps channels (using mature NRZ modulation) onto a single duplex fiber pair. This layout maximizes spectral and fiber utilization, significantly cutting down dark fiber provisioning overheads.
Standard Duplex LC Interface
- Features a compact, industry-standard LC duplex connector that matches mainstream single-mode fiber networks perfectly. It eliminates the need for specialized parallel cabling architectures (like MPO), ensuring seamless retrofitting and heavily simplifying field installations.
Compact QSFP28 Form Factor for High Density
- The pluggable QSFP28 form factor enables ultra-high port density on modern core switches and routers. This allows operators to scale their 100G uplinks efficiently without consuming excessive, high-cost rack space.
Full Standards Compliance & Factory Calibrated
- Fully compliant with IEEE 802.3ba (100GBASE-LR4) and OTU4 specifications, ensuring excellent cross-brand hardware interoperability. Pre-tested and factory-calibrated with full real-time DOM/DDM support to guarantee error-free plug-and-play readiness.
