How to Understand PoE and PoE+ Switches

Power-over-Ethernet (PoE) is the technology that allows network switches to transmit power and data through an Ethernet cable at the same time. PoE switch streamlines both of the processes of powering and providing data to the device, which makes it a...

What Are OM1, OM2, OM3 and OM4 Fiber Patch Cable?

Fiber optic cable can be divided into several types. Usually we see single-mode and multimode fiber types available on the market. Multimode fibers are described by their core and cladding diameters. The diameter of the multi-mode fiber is either 50/125...

Why Third-party 40G QSFP+ Transceiver, Instead of OEM QSFP Module?

For the data center or network upgrade, 40G network is a trending choice. Then where do you buy the 40G QSFP transceiver? Will you choose an OEM one or a third-party one? There are some differences between third-party 40G QSFP transceiver and OEM 40G...

Introduction to Semiconductor Optical Amplifier (SOA)

Optical amplifier, with the introduction in 1990s, conquered the regenerator technology and opened doors to the WDM technology. It is mainly used to amplify an optical signal directly, without the need to first convert it to an electrical signal. There...

Cisco Vs Huawei – Which One is the better Choice for Ethernet Switches?

Cisco, as the big brother in the telecom industry, has dominated the market of networking devices (like routers and switches) for a long time. No one can compete with him. Huawei, however, is the rising star in Chinese market. It ranked 83rd in the latest...

Mikrotik Vs Ubiquiti – Which One is Better for Home Network?

Ubiquiti Networks and Mikrotik were the rising stars in telecom field for the past year and a half, I have heard various fiber optic technicians telling me that Ubiquiti is better suited wireless applications while Mikrotik is excellent at what it does...

Four Basic Elements in a WDM System

We know that fiber can carry more data over long distances than any other physical medium. That makes fiber a very precious material. And how to make the most use of your fiber plant becomes a question. So there comes Wavelength Division Multiplexing...

How to Build 10G Network Within Budget

Modern business have become increasingly digital for cloud and data center application, which means everything from sales and marketing to service and support, rely heavily on a fast and reliable network. In 2017, Gigabit Ethernet data rate is no longer...

SFP-25G-SR & SFP-25G-LR SFP28 Optical Transceivers for 25G to 100G Migration

25G Ethernet was treated as the “new” 10GbE technology once it came out in 2014. Similar to 10G Ethernet that was based on 1 x 10Gbps lane scheme, 25GbE physical interface delivers 1 x 25Gbps more data. 25GbE technology with one single lane obviously...

CFP 100GBASE-SR10 VS. 100G QSFP28 100GBASE-SR4

With the price of 100G optics cutting down, 2017 witnesses the great expansion of `100G hardware market. QSFP28 and CFP 100G optical transceivers are becoming popular among customers. Not only Cisco, HPE, Brocade, and Huawei, but the third party vendors...
