Difference Between GBIC and SFP

Difference Between GBIC and SFP

They are used to convert optical and electrical signals. GBIC stands for Gigabit Interface Converter and SFP stands for Small Form-factor Pluggable. ... SFP's being more compact is beneficial because the larger size of a GBIC module means that you can fit less in to a line card or switch.

What is a GBIC used for?

A gigabit interface converter (GBIC) is a transceiver that converts electric currents (digital highs and lows) to optical signals, and optical signals to digital electric currents. The GBIC is typically employed in fiber optic and Ethernet systems as an interface for high-speed networking.

What is GBIC port?

GBIC (Gigabit Interface Converter)

It connects to both Fibre Channel and Gigabit Ethernet (GbE) optical fiber cables. The GBIC module is hot pluggable. The same electrical port on the switch can connect to fibers of different types (multimode or single-mode) and different wavelengths.

What is difference between SFP and SFP +?

SFP and SFP+ transceivers are virtually identical in size and appearance. The primary difference is that SFP+ is an updated version that supports higher speeds up to 10Gbps. The difference in data rate also accounts for a difference in transmission distance—SFP typically has a longer transmission distance.

Why is SFP used?

SFP ports and their corresponding SFP modules are used to facilitate seamless, high-speed data communications or telecommunications connections over extended distances in a variety of applications.

What is GBIC and SFP for?

They are used to convert optical and electrical signals. GBIC stands for Gigabit Interface Converter and SFP stands for Small Form-factor Pluggable. Although relative models of each technology are equal in performance, SFP's are generally considered as an upgraded version of a GBIC module, because they are smaller.

What does SFP stand for?

The small form-factor pluggable (SFP) is a compact, hot-pluggable network interface module used for both telecommunication and data communications applications. An SFP interface on networking hardware is a modular slot for a media-specific transceiver in order to connect a fiber-optic cable or sometimes a copper cable.

Are all SFP modules the same?

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. ... If you plug an SFP device into an SFP+ port, the speed will be locked at 1 Gbps.

What are the different transceiver types that have made the GBIC obsolete?

Newer transceivers that have made the GBIC obsolete include: * SFP (small form-factor pluggable)-Provides the same function as GBICs and is more compact, allowing more ports per linear inch. Also known as mini GBICs or SFP GBICs. Typically used for 1 Gbps connections, but theoretically capable of 5 Gbps.

Can SFP connect to RJ45?

Connecting SFP+ to RJ45 directly is not possible only with CAT cable. A special 10G Copper RJ-45 Transceiver (10G-SFP-T) is required to connect SFP+ port to RJ45. This transceiver is inserted in SFP+ port (cage) – used as an adapter.

Is SFP faster than Ethernet?

Since Rj45 Ethernet port and the SFP port actually run at the same speed, choosing the RJ45 ports to connect the switches might be more economical since Cat5e/6 cable is lower-priced than the SFP transceiver module.

How many types of SFP are there?

How Many Types of SFP Module?

SFP TypesTransceiver TypeDistance
SFP Fiber ModuleSX, MX, LX, EX, ZX, EZX, BX100m-160km over MMF or SMF
CWDM/DWDM SFP10km-120km over SMF
SFP Copper Module1000BASE-T100m over Copper Twist Pair Cable
10/100BASE-T100m over Copper Twist Pair Cable

Can 10Gb SFP run at 1Gb?

Will 10Gb SFP+ run at 1Gb? The answer is definitely “No”. That's because you can not down rate a 10G SFP+ transceiver. Once a module is installed, the speed of the port is unchanging.
