Frequently Asked Questions

Troubleshooting

Ensure the Network Device is running a compatible Firmware Version on a compatible Operating System. Please consult the manufacturer of the Network Device for more information regarding the minimum required or recommended system software.

Before You Buy

UPC and APC are fiber connector types. UPC (Ultra Physical Contact) connectors have a fiber connector end face that has been polished to a dome-shape. APC (Angled Physical Contact) connectors have a fiber connector end face that has been polished at an eight degree angle. When building fiber solutions, be sure to avoid mixing UPC and APC connectors. UPC and APC cannot mate with one another because causes the fiber cores don’t touch. This can cause a degraded connection or none at all.

StarTech.com fiber products use UPC connectors.

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.
