FAQ

 

1. What is a 1G Copper SFP module, and how is it different from a fiber SFP?
 
A 1G Copper SFP module, also known as an RJ45 SFP, uses a standard RJ45 connector and transmits data over regular copper Ethernet cables rather than fiber optic cables.
This makes it a practical and cost-effective solution when you need to add copper ports to a fiber-based switch or when fiber cabling is not available in your environment. There is no need to purchase additional media converters or run new fiber lines.
It is an ideal choice for short-distance connections within the same building or server room, typically supporting distances of up to 100 meters over Cat5e or Cat6 cable.
 
2. Is your 1G Copper SFP module compatible with my switch brand?
 
Our 1G Copper SFP modules are designed to be compatible with most major switch brands, including Cisco, Huawei, H3C, Juniper, MikroTik, Ubiquiti, and many others.
Each module is programmed with the appropriate coding to ensure seamless recognition without triggering third-party compatibility warnings on managed switches.
If you are unsure whether our module will work with your specific switch model, please share the model number with us and our technical team will confirm compatibility before you place your order.
 
3. Do copper SFP modules run hot? Will it affect my switch?
 
It is completely normal for 1G Copper SFP modules to generate more heat than fiber SFP modules. This is due to the additional circuitry required to drive signals over copper cable.
Our modules are designed and tested to operate stably within the standard industrial temperature range, and they comply with the thermal requirements defined by the SFP MSA specification.
As long as your switch has adequate ventilation and the modules are used within their rated specifications, there will be no negative impact on switch performance or lifespan.
 
4. What cable type and maximum distance does the 1G Copper SFP support?
 
Our 1G Copper SFP modules support transmission distances of up to 100 meters using Cat5e, Cat6, or Cat6a Ethernet cables, which aligns with the standard IEEE 802.3ab specification for 1000BASE-T.
The modules also support auto-negotiation, meaning they can automatically adapt to 10M, 100M, or 1000M speeds depending on the connected device, ensuring broad compatibility across different network environments.
For distances beyond 100 meters, we recommend considering a fiber SFP solution combined with fiber cabling, and we are happy to assist you in selecting the right alternative.
