Q、Are 1G SFP optical devices compatible with downshifted SFP+ ports?

A、The compatibility of 1G SFP modules with 10G SFP+ ports heavily relies on the specific switch model. Generally, SFP+ slots are compatible with SFP modules but typically operate at the slower speed of 1 Gb/s. In certain scenarios, an SFP+ port may limit the speed to 1 Gb/s until the switch is restarted or a specific command is issued. It’s crucial to remember that SFP+ ports usually do not support speeds below 1 Gb/s, hence they cannot accommodate 100BASE SFP modules.

Before inserting an SFP transceiver into an SFP+ port of a 10-gigabit switch, ensure that the switch vendor or Walsun’s official front-end interface supports dual-rate functionality. This step aids in assuring seamless network operations.

Q、What is an SFP port on a Gigabit switch?

A、An SFP port on a Gigabit switch is a slot designed to accommodate SFP connectors for facilitating data transmission. It boasts high speed and a compact physical design. The SFP port enables fiber or copper connections on a Gigabit switch; by deploying the appropriate SFP module, whether fiber optic or copper, you can establish either type of link on the switch. When an SFP module is installed in a Gigabit switch with electrical ports, Ethernet cables such as Cat5e or Cat6e are connected to the SFP port. Data transmission necessitates the use of network cables like Cat5e/Cat6/Cat7. Conversely, if the SFP module is installed in a Gigabit switch equipped with optical ports, fiber optic cables are required to support the connection.

Q、What is the warranty period for Walsun 1G SFP transceivers?

A、Our optical modules come with a 3-year warranty. This warranty covers defects arising during normal usage and does not encompass failures or malfunctions resulting from misuse, abuse, neglect, modifications, power issues, disregard for product instructions, natural causes, or improper installation, operation, or repair by non-Walsun or unauthorized Walsun service providers.
