An Irresistible Trend- 100 Gigabit Ethernet

In 2006, the IEEE 802.3 working group formed the Higher Speed Study Group (HSSG) and found that the Ethernet ecosystem needed something faster than 10 Gigabit Ethernet. Because the growth in bandwidth for network aggregation applications overpasses the capacities of networks employing link aggregation with 10 Gigabit Ethernet. HSSG is the [ Continue reading…]

Copper SFP Transceiver for 1000BASE Applications

In the past, because of low cost and compatibility with existing LANs, 100Mb/s Ethernet was very popular. As people’s increasing demands for faster delivery of information, high bandwidth Ethernet LAN is evolving. 1000BASE (1 Gbps Gigabit Ethernet) came around and brought Ethernet technology to a new stage. Gigabit Ethernet, as [ Continue reading…]

General Understanding of LC to LC Fiber Optic Cables

Fiber optic patch cords are also known as fiber optic jumpers or fiber optic patch cables. Fiber optic patch cords are designed to provide optical connection for fiber networks within structured cabling systems. It’s a quick and easy method for routing fiber patches in data centers, head-ends, cellular hubs and [ Continue reading…]

Why Is CWDM so Popular?

WDM (wavelength division multiplexing) technology transmitting multiple signals on a single optical fiber by using different wavelengths to carry each signal has been used since 1980s. In the middle of 1990s, dense wavelength division multiplexing (DWDM) enabled carriers to extend the capacity of the SONET/SDH rings in the network core, [ Continue reading…]

Multi-fiber Connectors for High Port Density

As the introduction of multimode optical fibers of the categories OM3 and OM4 are used for implementing 40 GbE and 100 GbE, though the small diameter of the optical fibers poses no problems in laying the lines, the ports suddenly have to accommodate four or even ten times the number [ Continue reading…]

Should We Use Third-Party Compatible SFP Transceiver?

Many customers tend to use third-party compatible Cisco SFP transceivers to save costs on these expensive modules. But there maybe a problem that the Cisco’s new line switches do not support third-party SFPs. When inserting an SFP transceiver into Cisco switches to connect network backbone, you will find it doesn’t [ Continue reading…]

How to Install and Remove a SFP Transceiver?

SFP is short for small form-factor pluggable. It’s a compact, hot-pluggable transceiver used for telecommunication and data communications. The form factor and electrical interface are specified by a multi-source agreement (MSA). It interfaces a network device motherboard (for a switch, router, media converter or similar device) to a fiber optic [ Continue reading…]

What Does DOM Mean for a SFP Transceiver?

If you take a look at the description of a SFP transceiver module, you will see the “DOM support” appeared in the product details. What does it mean? In fact, DOM or Digital Optical Monitoring as the words implies, is used for monitoring some parameters of the transceiver, which can help to [ Continue reading…]
