Linksys Ea4500 Wireless Router Setup

Linksys EA4500 is App Enabled N900 Dual-Band Wireless Router with Gigabit Ethernet port.
What is app enabled router? A router that can run an ever expanding selection of apps for accessing your home network and the devices connected to it.
Linksys EA4500 router Features:
The Linksys EA4500 has transfer rates of up to 450 + 450 Mbps.
Dual-band technology – It doubles your network bandwidth with its simultaneous dual-band N 2.4 and 5 GHz designed to avoid interference and maximize throughput for smoother and faster HD video streaming, file transfers.
It has four (4) Gigabit Ethernet (10/100/1000) ports for quick file sharing between other Gigabit-enabled devices like computers, hard drives, and servers. EA4500 also has Full 33 MIMO antenna array which boosts signal strength on 2.4 and 5 GHz radios.
USB Storage Port Add external storage, printers and other devices to share across your network.
IPv6 enabled IPv6 is a new IP protocol that uses simplified packet headers and requires IPSec as a fundamental interoperability requirement.
Guest Access You can grant Internet access to visiting friends and family. It allows you to provide Internet access up to 50 guests visiting your home without granting them access to your local network.
How to setup Linksys EA4500 using Cisco connect software:
Before running the Cisco connect software, connect your computer to the Internet modem and make sure that you have active Internet through the modem.
Then connect the modem to the Internet port on E EA4500 and computer to port 1. You can run Cisco connect software on wireless computer also. But I will recommend you to connect the computer to the Ethernet port to avoid error messages.
Run the Cisco connect program and it will setup your router automatically. It will also create a unique secured wireless network and a Guest wireless network also. At the end of the program you will be able to see the router settings, network name and password, guest access password.
You can manage guest settings using the web interface of the EA4500. So it is not necessary to install the Cisco connect software to manage guest network as it was the case with E1000, E2000 and E3000 wireless routers.
How to setup Linksys EA4500 without Cisco connect software:
You can also setup Linksys EA4500 router manually without Cisco connect software.
Connect the modem and computer to the router with the Ethernet cable.
Open the setup page of Linksys EA4500 and change the Internet connection settings manually according to your Internet service provider.
Once you change the Internet connection settings, your main computer will be able to access the Internet. Then change the wireless settings manually and make your wireless network secured.

Sfp Transceivers For Telecommunications

The SFP may be the smaller sized optical transceiver utilized in optical communications. It interfaces a network equipment mother board to some fiber-optic or unshielded twisted pair networking cable.
This is probably the most diffused transceiver format available with a number of different transmiter and receiver types, allowing users to select the appropriate transceiver for each connect to supply the required optical reach within the available optical fiber (e.g., multi-mode fiber or single-mode fiber).
A drawing of SFP module is presented below, where the particular connector for the input and output fibers that, with different dimensions, exists in all the transceivers is evidenced. The way in which the SFP transceivers are hosted on the motherboard utilizing a suitable cage allowing a hot plug is show in the figure below, where both empty cages around the front of a system card and also the cages with plugged SFPs are provided.

Optical SFP modules are commonly obtainable in a choice of models: 850 nm (SX), 1310 nm (LX), 1550 nm (ZX), and WDM, both DWDM and CWDM. SFP transceivers are also available with a copper cable interface. The copper SFP allows a host device designed primarily for optical fiber communications to also communicate over unshiedled twisted pair networking cable.
Commercially available transceivers have a capability as much as 2.5 Gbps for transmission applications; moreover, a version of the standard having a bit rate of 10 Gbps exists, however it can be used only to connect nearby equipment, and it is very helpful to spare space and power consumption as interface within the client cards of line equipments.
Modern optical SFP transceivers support digital monitoring functions based on the industry standard SFF-8472 MSA. This selection gives the consumer the opportunity to monitor real-time parameters from the SFP, for example optical output power, optical input power, temperature, laser bias current, and transceiversupply voltage.
SFP transceivers are designed to support SONET, Gigabit Ethernet, Fibre Channel, and other communications standards.
The standard is expanding to SFP (SFP plus), which will be capable of supporting data rates as much as 10.0 Gbps (that will range from the data rates for 8G Fibre Channel, and 10 GbE). Possible performances of various realistic SFP transceivers are reported in the figure below.
