How To Use A Fiber Optic Patch Panel

图片
  What Is a   Fiber Optic Patch Panel? Patch panel is defined as the interface between multiple optical fibers and optical equipment. It’s a termination unit that helps networking and fiber distribution from wiring closet to various terminal equipment. Fiber optic patch panel is a mounted hardware unit containing an assembly of port locations in a communication or other electronic or electrical system. Fiber optic patch panel is used to terminate the fiber optic cable and provide access to the cable’s individual fibers for cross connection. They are mostly mounted in 19 inch relay racks, but they can also be mounted on freestanding rails, in cabinets and also on walls. Fiber Optic Patch Panel Types Fiber optic atch panel are divided into two types based on different designs, the wall mount and rack mount category. Both types can house, organize, and protect fiber optic cable and connectors. Rack mount patch panels  come in flat and angled versions wh...

How to Configure DHCP for Multiple VLANs?

图片
Almost every device connected to the Internet needs an IP address. Previously, the countless IP addresses are assigned manually, which costs a lot of time and energy. As DHCP emerges, IT specialists are not required any longer to spend countless hours providing IPs for every device connected to the network device. But what is DHCP? How does it work and how to configure DHCP for multiple VLANs? What Is DHCP? DHCP – Dynamic Host Configuration Protocol is a network management protocol used on TCP/IP network. There may be at least a DHCP server and many DHCP clients. The DHCP server allows the client to request the IP addresses and other network configurations from the Internet service provider. This process eliminates the need for administrators or users to assign IP address to network devices one by one. Using this protocol, the network administrators will just set up the DHCP server with all the additional network information, and it will do its work dynamically. Both network switc...

Optical Transceiver Wiki

The optical transceiver, the transmission carrier between the switchboard and the device, consists of optoelectronic devices, functional circuits, and optical interfaces. The optoelectronic devices include transmitting and receiving parts. The optical transceiver aims to achieve photoelectric conversion and is more efficient and safer than the converters. The transmitting end converts the electrical signal into an optical signal. After being transmitted through the optical fiber, the receiving end converts the optical signal into an electrical signal. In this article, we will discuss the transceiver from two perspectives, that is, optical transceiver types and how to choose an optical transceiver. Optical Transceiver Types Before discussing how to select an optical transceiver, we need to have a basic understanding of common packaged optical transceiver. In this part, the SFP, SFP+, QSFP+, and QSFP28 packaged optical transceivers will be introduced respectively. SFP Optical Tran...
