Fiber Optic Communication

It is universally acknowledged that price is one of the key factors when we buy something. We may heave a sigh of the soaring cost of the switches of the major brands on the current market, such as Cisco, Arista, Juniper...However, that is not a good deal for home and some small enterprises to make Ethernet network connectivity. Ubiquiti POE switches provide a perfect solution for this deadlock. This article would provide the detailed information about Ubiquiti US-8-150W POE switch—its compatible Ethernet cables and SFP modules as well as connection solution. Why Choose Ubiquiti US-8-150W POE Switch? Nowadays, a lot of families choose Unifi to make Ethernet connection and Ubiquiti sells Unifi-compatible POE switches. Lately, the company has just launched its line of Unifi switches with two more models better suited for home use: the 16-port US-16-150W and the fanless 8-port US-8-150W. They are silent and unobtrusive. The highlight lies in their price, they only cost $299 and $19...

Multimode fiber optic cable has been widely used in our daily life for its cost-effective, low power consumption and etc. The OM family recently was added a new member, called as OM5. Different from the previous OM1 to OM4, OM5 is a wideband multimode fiber, which will support short wavelength division multiplexing (SWDM). This article would provide general information about OM5 and differences between OM5 and OM3, OM4. Information About OM5 As early as 2016, Commonscope introduced their LazrSPEED Wideband Multimode Fiber (WBMMF), and the ISO/IEC decided the nomenclature for WBMMF is OM5 in October 2016. Later, wideband OM5 fiber was defined by IEEE 802.3bs, which refers as a multimode 400Gb/s link, 400GBASE-SR16, using 16 transmit and 16 receive fibers (32 fibers total) over a link distance of 100 m. Currently it shows that OM5 wider operating window offers no immediate advantages compared with OM4 fiber. But using OM5 will make the network ready for future use of SWDM technolo...
