Cisco QSFP-40G-LR4 Compatible QSFP+ Module - 40GBASE-LR4 - 40GbE Single Mode Fiber SMF Optic Transceiver - 40GE Gigabit Ethernet QSFP+ - LC 10km - 1270nm to 1330nm - DDM Cisco Firepower, ASR1000, ASR9000

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.  

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.
