Q: What is the difference between the electrical interface module SFP-GE-T and optical interface modules?

A: The electrical interface module SFP-GE-T and optical interface modules have some differences in terms of signal transmission methods and application environments:

• Signal Transmission Mode: Electrical interface modules utilize electrical signals for transmission, whereas optical interface modules employ optical signals. Optical signal transmission offers higher bandwidth and speed, making it suitable for long-distance transmissions.
• Operating Environments: Electrical interface modules are suited for short-range transmissions and smaller network environments such as offices or home networks. Optical interface modules, on the other hand, are designed for large-scale network environments like data centers and enterprise networks.

Q: Can Gigabit Ethernet ports interoperate with 100Mbps ports? Can Gigabit Ethernet ports also interoperate with 10 Gigabit Ethernet ports?

A: Gigabit Ethernet ports can directly interoperate with 100Mbps ports, but the data transfer rate will be limited to the slower 100Mbps Ethernet speed. When a Gigabit Ethernet port connects to a 100Mbps port, the data transmission rate will be constrained to the 100Mbps rate.

Interoperation between Gigabit Ethernet ports and 10 Gigabit Ethernet ports requires intermediary devices, such as switches. When connected through a switch, Gigabit and 10 Gigabit Ethernet ports can communicate, but the speed will still be limited by the slower port’s capability. It is important to note that the prerequisite for such interconnectivity is that the 10 Gigabit Ethernet port of the network device using the electrical interface module supports Gigabit speeds.

Q: How long is the warranty period for Walsun 1G SFP transceivers?

A: Our optical modules come with a 3-year warranty. This warranty covers defects that occur under normal usage conditions and does not apply to damages or malfunctions resulting from misuse, abuse, negligence, modifications, power issues, failure to follow product instructions, natural factors, or improper installation, operation, or repairs by non-Walsun or unauthorized Walsun service providers.
