Are SFPs interchangeable?
SFP and SFP+ modules look exactly the same. And as they have the same size, your SFP transceiver will fit seamlessly into an SFP+ switch port and vice versa.
Can I mix and match SFP modules?
Instead of being standardized by official standards, SFP is specified by MSA. SFP transceivers meeting the SFP Compatibility requirement are usually compatible across a range of telecoms vendors’ hardware, therefore users can mix and match components from different vendors.
Can I use any SFP module?
If a device requires coded SFP modules (i.e. Cisco / HP) then you need either the OEM module or a compatible version. If the device does not require coded SFP (i.e. Netgear) then you can use any SFP, even a Cisco.
How do I know which SFP to use?
When choosing SFP modules, you should consider whether it matches the switch port and the cable you have prepared. If you have multimode cable, then you can choose GLC-SX-MM 1000BASE SFP. If you use single-mode fiber cable, you should select GLC-LH-SM 1000BASE SFP.
Will SFP module work in SFP+ port?
SFP modules may can be used in SFP+ slot, but a SFP can never be connected to a SFP+ module. For their different speeds, transmission distance and wavelength. 10 SFP+ only can use for 10G SFP+ port, and can never auto-negotiate to 1G.
Will a SFP module work in a SFP+ port?
Can SFP+ support 10Gb?
The answer is definitely “No”. SFP optics do work in SFP+ slots in most cases, but SFP+ optics on 10Gb switch can never work in SFP slots on gigabit switch. However, the SFP slots on gigabit switch cannot support the 10G speed required by SFP+ modules.
Is LX multimode?
1000BASE-LX can run over both single mode fiber and multimode fiber with a distance of up to 5 km and 550 m, respectively. For link distances greater than 300 m, the use of a special launch conditioning patch cord may be required.
Will SFP module work in SFP+?
How many GBIC modules can I have on my System?
You can have a maximum of 12 1000BASE-ZX GBIC modules or SFP modules per system to comply with EN55022 Class B and 24 1000BASE-ZX GBIC modules or SFP modules per system to comply with FCC Class A regulations.
What type of cable do I need to pair the GBIC module?
The 1000BASE-ZX GBIC module must be coupled to single-mode fiber-optic cable, which is the type of cable typically used in long-haul telecommunications applications.
What are the GBIC and SFP devices used for?
The devices are used on Cisco platforms that have Gigabit Ethernet interfaces. Also see the documentation that shipped with the GBIC module or SFP module or the installation guide for your router, I/O controller, processor engine, or port adapter.
How many channels does the Cisco CWDM GBIC module support?
The Cisco CWDM GBIC module and SFP modules enables the transport of up to eight channels (Gigabit Ethernet over single-mode fiber strands. (They also support the transport of up to eight channels [Fiber Channel] over single-mode strands, although Fiber Channel is not discussed in this document.)
