Active Networking Components are those devices which in some way actively work with signals. Therefore , here are some of the active devices we deal in are :
PRINT SERVER
NETWORKING SWITCH :
Most business networks today use switches. In order to connect computers, printers, phones, cameras, lights, and servers in a building or campus . Although a switch serves as a controller, enabling networked devices to talk to each other efficiently. Through information sharing and resource allocation, switches save businesses money and increase employee productivity.

MEDIA CONVERTER :
Media Converters easily connect two different types of devices or networks together. While linking copper and fiber networks together in the common application, Fiber Media Converters also enable users to join together two multi-mode networks or link multi-mode to single mode for longer data transmission distances. Hence, Media Converters are also the perfect solution to convert and extend various types of data signals throughout your network. For example, If you have two devices or LAN that do not match, due to different speeds, operation types, modes or cable types, you are in the right place. 
SFP TRANSCEIVER / MODULE :
Firstly SFP stands for (Small Form-factor Plug-able). A small transceiver that plugs into the SFP port of a network switch and connects to Fiber Channel and Gigabit Ethernet (GbE) optical fiber cables at the other end. Superseding the GBIC transceiver, SFP modules are also called “mini-GBIC” due to their smaller size. 
ROUTERS :
This is to say that Routers connect networks. In addition, A router is hardware device designed to receive, analyze and move incoming packets to another network. It may also be used to convert the packets to another network interface, drop them, and perform other actions relating to a network. (1) it connects multiple computers, phones, tablets, or other devices to form a managed local area network, and (2) it provides Internet access to all of the compatible devices that are connected to the router. 
ACCESS POINTS :
An access point is a wireless network device that acts as a portal for devices to connect to a local area network. Therefore, Access points can extend the wireless coverage of an existing network and to increase the number of users that can connect to it.
A high-speed Ethernet cable runs from a router to an access point, which transforms the wired signal into a wireless one. To sum up , Wireless connectivity is typically the only available option for access points, establishing links with end-devices using Wi-Fi. 
PoE INJECTOR :
A PoE injector connects your PoE-enabled network device to a non-PoE LAN switch port.
More specifically, a PoE injector can connect a wireless access point, IP phone, network camera or any IEEE 802.3af/at-powered device (PD) to a network switch. Using a PoE injector avoids the need to run AC power lines for your wireless access point, network camera or IP phone, because you use the existing LAN cabling to deliver both DC power as well as data. 
PRINT SERVER :
A print server, or printer server, is a device that connects printers to client computers over a network. It accepts print jobs from the computers and sends the jobs to the appropriate printers, queuing the jobs locally to accommodate the fact that work may arrive more quickly than the printer can actually handle.
