Frequently Asked Questions
Before You Buy
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.
