Frequently Asked Questions

Before You Buy

How can I tell if this SFP will be compatible with my network equipment?

SFP fiber transceivers (mini-GBIC) are specific to applications and therefore, you need to select the correct fiber transceiver for your application. StarTech.com offers a few types of fiber transceivers: Cisco®, Cisco Meraki®, HP®, and Juniper® compatible, as well as standard gigabit SFP converters. Although the transceivers may be referred to as GBIC or mini-GBIC, the correct terminology for the device is small form-factor pluggable transceiver or SFP . StarTech.com does not carry GBIC converters.

If your device is not a Cisco device, it can still use Cisco compatible SFPs. Cisco SFPs are specifically coded to be compatible with Cisco devices. A standard SFP will not work in a Cisco device.

StarTech.com offers two different output connector types for SFPs: RJ-45 and fiber.

No special requirements are necessary to use RJ-45 SFPs. However, if you use fiber transceivers, the following items need to be the same as the interconnecting equipment:

The connector type, such as LC, SC, or ST.
The mode (single mode or multi mode).
The wavelength, such as 850 nm, 1310 nm, or 1550 nm.
The DDM support.
The speed, such as 10Gbps.

Note: The properties listed above cannot be converted or changed by a cable, excluding the connector type.
