1.25G BIDI SFP+ ZX 1550Tx 1490Rx 80km

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. In general, SFP+ slots are compatible with SFP modules; however, they typically operate at speeds slower than 1Gb. Sometimes, an SFP+ port may restrict the speed to 1Gb until the switch is restarted or a specific command is issued. It’s important to remember that SFP+ ports typically don’t support speeds below 1G, thus they can’t accommodate 100BASE SFP modules.

Before inserting an SFP transceiver into an SFP+ port of a 10-gigabit switch, ensure that the switch vendor’s documentation or the official interface specifications support dual-rate operation. This will help ensure uninterrupted network performance.

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

A、An SFP port on a gigabit switch is a receptacle designed to accept SFP connectors for data transmission. It boasts high speed and a compact physical profile. By installing the appropriate SFP module, whether fiber optic or copper, the SFP port facilitates fiber or copper connections on the gigabit switch. When installing SFP modules into an electrically-enabled gigabit switch, Category 5e, 6, or 7 cables are required for data transfer. Conversely, optical cables are necessary when installing SFP modules into gigabit switches equipped with optical ports for connectivity.

Q、What are the primary considerations when purchasing SFP transceivers?

A、There are seven main 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 maintain functionality and reliability. All our transceivers undergo rigorous testing in our test centers using popular original brand switches before shipment, ensuring they meet high-performance requirements from customers.
