FAQ
Q1: What is the difference between QSFP-100G-SR4 and LR4 modules?
A: SR4 uses multimode fiber (MMF) and is designed for short distances (up to 100m), while LR4 uses single-mode fiber (SMF) and supports long distances up to 10km.
Q2: Can QSFP-100G-SR4 work with existing 40G SR4 infrastructure?
A: In some cases, yes. It depends on switch compatibility and breakout configuration. Many networks support 100G SR4 backward compatibility via MPO cabling.
Q3: What fiber type is required for this module?
A: It requires OM3 or OM4 multimode fiber with MPO/MTP connectors.
Q4: Is this module compatible with Cisco, Huawei, and Juniper switches?
A: Yes, it is designed to be MSA-compliant and compatible with major networking brands when properly coded.
Q5: What warranty and support do you provide?
A: Typically, the module comes with a 1-year warranty, including replacement or technical support for compatibility and performance issues.
Why Choose This QSFP-100G-SR4 Module?
This transceiver offers a cost-effective upgrade path to 100G networking without requiring expensive single-mode fiber infrastructure. It is ideal for enterprises and data centers seeking high bandwidth, low latency, and simplified deployment.
