1.25G BIDI SFP LX 1310Tx 1550Rx 10km

Q、What types of SFP optical modules are there?

A、SFP optical modules are small, hot-pluggable transceiver devices widely used in the telecommunications industry. They come in various types, such as BIDI-SFP, Ethernet SFP, CWDM SFP, DWDM SFP, and SFP+ modules. Furthermore, compared to similar modules like XFP, X2, and XENPAK, SFP modules not only directly connect but also offer a more cost-effective solution.

Q、Is a 1G SFP optical device compatible with a downgraded SFP+ port?

A、The compatibility of a 1G SFP module with a 10G SFP+ port largely depends on the specific switch model. Generally, SFP+ slots are compatible with SFP modules, but they typically operate at the slower 1Gb speed. In some cases, the SFP+ port may limit the speed to 1Gb until the switch is restarted or a specific command is issued. Remember, SFP+ ports usually don’t support speeds below 1Gb. Thus, SFP+ ports cannot accommodate 100BASE SFP modules.

Before inserting an SFP transceiver into a 10-gigabit switch’s SFP+ port, ensure the switch vendor or Walsun’s official front-end interface supports dual-rate functionality. This ensures seamless network operation.

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

A、An SFP port on a Gigabit switch is a slot that accepts an SFP connector for data transmission. It’s high-speed and physically compact. The SFP port enables fiber or copper connections on a Gigabit switch. By inserting the appropriate SFP module (fiber optic SFP or copper SFP), fiber or copper connections can be established on the Gigabit switch. When an SFP module is installed in a Gigabit switch with an electrical port, Ethernet cables like Cat5e/Cat6e are connected to the SFP port. Network cables such as Cat5e/Cat6/Cat7 are required for data transmission. Conversely, when an SFP module is installed in a Gigabit switch with an optical port, fiber optic cables are needed to support the connection.

Q、What are the main considerations when purchasing an SFP transceiver?

A、There are seven key considerations: network technology, transmission medium, wavelength, operating temperature, compatibility, DOM support, and price/budget.

Q、How does Walsun ensure the compatibility and performance reliability of its compatible transceivers compared to branded ones?

A、In addition to being priced lower than branded transceivers, Walsun’s compatible transceivers continue to function normally and maintain reliability. All our transceivers undergo multiple tests in our test center with popular original brand switches before shipment to meet customers’ high-performance demands.

Q、How long is the warranty period for Walsun’s 1G SFP transceivers?

A、Our optical modules come with a 3-year warranty. The warranty covers defects occurring under normal use only and excludes failures or malfunctions resulting from misuse, abuse, neglect, modification, power issues, non-adherence to product instructions, natural causes, or improper installation, operation, or repair by anyone other than Walsun or an authorized Walsun service provider.
