1.25G DWDM SFP CH17-CH61 80km

Q、What types of SFP optical modules are there?

A、Types of SFP optical modules include Dual-Fiber SFP, Single-Fiber BiDi SFP, CWDM SFP, DWDM SFP, Electrical Interface SFP, EPON SFP, and GPON SFP, among others.

Q、What is the warranty period for 1.25G SFP transceivers?

A、Our optical modules come with a 3-year warranty. This specifically covers defects arising under normal usage conditions and does not apply to malfunctions or failures resulting from misuse, abuse, neglect, modification, power issues, failure to follow product instructions, natural disasters, or improper installation, operation, or repair by non-Walsun or non-Walsun authorized service providers.

Q、What are the application scenarios for 1G SFP transceivers?

A、1G SFP transceivers, with their ultra-low power consumption and high efficiency, are ideal choices for various networking environments, including Gigabit Ethernet communication links for Internet Service Providers (ISPs). Furthermore, their compatibility extends to enterprise LANs and SANs, as well as data center LANs and SANs, with hot-swappable capability ensuring seamless integration.

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

A、The compatibility of 1G SFP modules with 10G SFP+ ports largely depends on the specific switch model. Generally, SFP+ slots are compatible with SFP modules; however, they typically operate at speeds slower than 1Gb. In some instances, an SFP+ port may limit the speed to 1Gb until the switch is restarted or a specific command is issued. It’s important to note that SFP+ ports usually do not support speeds below 1G, thus they cannot accommodate 100BASE SFP modules.

Before inserting an SFP transceiver into an SFP+ port of a 10-gigabit switch, ensure that dual-rate support is documented by the switch vendor or in the official front-end interface documentation. This helps ensure a faultless network operation.
