Cisco GBIC 1G/
The Cisco GLC-SX-SMD is a 1000BASE-SX Small Form-Factor Pluggable (SFP) transceiver module that provides Gigabit Ethernet connectivity over multimode fiber (MMF) links. It supports a wavelength of 850 nanometers (nm) and can operate over distances of up to 550 meters (m) using legacy 50 μm MMF cable, or up to 1 kilometer (km) using laser-optimized 50 μm MMF cable.
The GLC-SX-SMD is compatible with Cisco switches and routers that have SFP slots, and it can be hot-swapped without interrupting network traffic. It also supports Digital Diagnostic Monitoring (DDM) and Digital Optical Monitoring (DOM), which provide information about the health of the module and the link.
Why use(Cisco GBIC 1G/ GLC-SX-SMD)
There are many reasons why you might want to use a Cisco GBIC 1G/ GLC-SX-SMD. Here are a few of the most common reasons:
- To extend your Gigabit Ethernet network over multimode fiber links. The GLC-SX-SMD supports 1000BASE-SX Gigabit Ethernet connectivity over MMF links, which means you can use it to connect devices that are up to 550 meters (m) or 1 kilometer (km) apart.
- To create a reliable and secure network connection. The GLC-SX-SMD is a hot-swappable module, which means you can replace it without interrupting network traffic. It also supports Digital Diagnostic Monitoring (DDM) and Digital Optical Monitoring (DOM), which provide information about the health of the module and the link.
- To save money. The GLC-SX-SMD is a cost-effective way to extend your Gigabit Ethernet network. It is also a good choice for use in harsh environments, as it is rated for operation in temperatures ranging from -40 to 70 degrees Celsius.
Here are some specific examples of where you might use a Cisco GBIC 1G/ GLC-SX-SMD:
Here are some additional benefits of using the Cisco GBIC 1G/ GLC-SX-SMD:
- It is compatible with a wide range of Cisco switches and routers
Learn more about SMD
here are two main types of SMD components: resistors and capacitors. Resistors are used to control the flow of electricity, and capacitors are used to store electrical energy. Other common SMD components include diodes, transistors, and integrated circuits.
SMD components are typically identified by their size and shape. The most common size designation is the EIA-0201 standard, which specifies a component that is 0.020 inches (0.5 mm) wide and 0.010 inches (0.25 mm) high. Other common size designations include 0402, 0603, and 1206.
SMD components are typically mounted on PCBs using a process called surface mount technology (SMT). SMT is a automated process that uses a machine to place the components on the PCB and then solder them in place.
SMT has several advantages over traditional through-hole mounting. First, SMT components are smaller and lighter, which can lead to smaller and lighter electronic devices. Second, SMT components are more efficient, which can lead to lower power consumption. Third, SMT is a more automated process, which can lead to faster and more consistent manufacturing.
As a result of these advantages, SMT has become the dominant method for mounting electronic components. Today, most electronic devices, from computers to smartphones to TVs, use SMT.

GBICs were first introduced in 1995 and were the standard for Gigabit Ethernet transceivers for many years. However, they have since been superseded by the Small Form-Factor Pluggable (SFP) transceiver, which is smaller and more efficient.
GBICs are available in a variety of types, including:
- 1000BASE-SX: This type of GBIC supports 1000 Mbps data transfer over multimode fiber cables with a wavelength of 850 nanometers (nm).
- 1000BASE-LX/LH: This type of GBIC supports 1000 Mbps data transfer over single-mode fiber cables with a wavelength of 1300 nm or 1550 nm.
- 1000BASE-CX: This type of GBIC supports 1000 Mbps data transfer over copper cables.
GBICs are typically mounted in a GBIC slot on a networking device. To install a GBIC, simply unplug the old GBIC and plug in the new one. GBICs are hot-swappable, which means they can be replaced without interrupting network traffic.
GBICs are a reliable and versatile way to connect devices over optical fiber cables. However, they are no longer the standard for Gigabit Ethernet transceivers. SFP transceivers are smaller, more efficient, and have become the preferred choice for most networking applications.
