Overview
This is a highly flexible, dual-rate SFP+ optical transceiver, engineered as a fully compatible and cost-effective equivalent to the Juniper Networks QFX-SFP-1/10GE-LR-X. Its key feature is its ability to operate at two distinct speeds: 10 Gbps (10GBASE-LR) and 1 Gbps (1000BASE-LX). This dual-rate capability makes it an exceptionally valuable tool for network administrators managing phased upgrades, mixed-speed environments, or requiring maximum hardware flexibility.
Using a reliable 1310nm DFB laser, this module can transmit high-speed data across distances of up to 10 kilometers over standard single-mode fiber (SMF). It is equipped with a Duplex LC connector, making it compatible with common fiber optic patch cables. Whether you are connecting a new 10G switch to a legacy 1G device or building a network with the future in mind, this transceiver provides a seamless and powerful solution.
Key Features
- 100% compatible with Juniper Networks platforms that support the QFX-SFP-1/10GE-LR-X module.
- Dual-Rate Functionality: Supports both 10GBASE-LR (10.3125 Gbps) and 1000BASE-LX (1.25 Gbps) standards.
- Long Reach: Transmits up to 10km over Single-Mode Fiber (G.652 SMF).
- High-performance 1310nm DFB transmitter and PIN photodetector.
- Connector: Duplex LC/UPC.
- Built-in Digital Optical Monitoring (DOM/DDM) for real-time diagnostics of power, temperature, and signal integrity.
- Hot-pluggable SFP+ form factor for installation without network interruption.
- Low power consumption and excellent EMI performance.
Applications
The unique dual-rate nature of the QFX-SFP-1/10GE-LR-X compatible module makes it ideal for:
- Phased network migrations from 1 Gigabit to 10 Gigabit Ethernet.
- Connecting new 10G equipment to existing 1G infrastructure.
- Service provider and enterprise aggregation links.
- Data center interconnects (DCI) and campus backbone networks.
- Reducing spare parts inventory by stocking a single module for two different speeds.

FAQ (Technical & Product Questions)
1. What exactly does “Dual-Rate” mean for this SFP+ module?
Dual-Rate means the transceiver contains the necessary components to operate at two different data speeds. In this case, it can function as a 10GBASE-LR module for 10 Gigabit Ethernet or as a 1000BASE-LX module for 1 Gigabit Ethernet. The operating speed is typically determined by the configuration of the host port it is plugged into.
2. Can I use this module to connect a 10G port to a 1G port?
No. While the module itself is capable of running at either speed, a network link can only operate at one speed at a time. Both devices at each end of the fiber link must be configured to operate at the same speed (either both at 1G or both at 10G). This module gives you the flexibility to use it in either a 1G link or a 10G link.
3. How does the switch know whether to operate at 1G or 10G?
This is controlled by the host device (the switch, router, or server). On most modern networking equipment, you can manually configure the port to operate at a fixed speed of either 1G or 10G. Some devices may also support rate-autonegotiation, but manual configuration is more common for fiber optic links.
4. Is this module different from a standard SFP-10G-LR transceiver?
Yes. A standard SFP-10G-LR module can *only* operate at 10 Gbps. The key advantage of the QFX-SFP-1/10GE-LR-X is its additional ability to operate at 1 Gbps, providing much greater flexibility for your network.
5. Will using this compatible QFX-SFP-1/10GE-LR-X void my Juniper equipment warranty?
No. Using third-party, MSA-compliant transceivers will not void your network equipment’s warranty. Antitrust laws in many countries (like the Magnuson-Moss Warranty Act in the US) protect consumers’ rights to use third-party hardware. Our modules are built to the exact same specifications as OEM parts and pose no risk to your equipment.
