Port SFP connection between Mikrotik RouterBoard

Development of Internet technology today is very rapid. Previously, people using the Internet are still using the old connection, but now I use a connection fast paced. Technology tools is growing along with the development of existing technologies. Many media used in the distribution of signals, one of which is fiber optic. Fiber optics can be regarded as one form of transmission of the light waves.

Supporting devices for the installation of communications systems using Fiber Optics that Optical connector, pigtail, SFP, etc. This time we will only discuss the SFP. SFP stands for Small Form-Factor Pluggable. SFP is a device that shortly transmit and me-receive signal information with fiber optic media. SFP is a development of Gigabit Interface Converter (GBIC). SFP also known as mini-GBIC. GBIC term means a port that is devoted to dealing with the backbone network with a large bandwidth.

SFP modules can be used on

Hotspot Authentication Using Active Directory

Active Directory (AD) is a service that is owned by the windows operating system for networks such as Windows 2000 Server, Windows Server 2003, Windows Server 2008, and Windows Server 2012. Active Directory consists of databases and directory services. The database is owned by Active Directory to store all the resources available in the network, such as computers that have been joined to a domain, a list of user accounts and user groups, shared folders, and others.As already known, AAA Mikrotik not only be done on the device itself, but can also use an external database of the RADIUS Server. This time, we will experiment with combining MikroTik with Active Directory on Windows 2003.

Service that can be used to be able to create a centralized AAA server is a component in Windows Internet Authentication Service (IAS). In addition, this service will act as a liaison between MikroTik Router with existing user database in Active Directory using standard RADIUS protocol.

Settings in Windows Server

Usually the IAS service is not yet active component in Windows Server, so it needs to be added and activated first. Click Start -> Control Panel -> Add / Remove Programs -> Networking services

Register components / IAS service in Active Directory so user-friendly in it can later be inserted and

Test Throughput Mode Wireless in MikroTik

In the wireless properties, there are many modes that can be used as needed. Wireless mode function to determine whether to enable the access point (transmitter), repeater, or enable the station (receiver). There are several modes that have almost the same function, call it eg station-bridge mode with station-pseudobridge. Now we will try to do testing mode selection effect on the throughput of data that is passed. Testing using standard band 802.11 B / G / N.

Access Point

There are only two modes that make interface works as a wireless access point. AP-Bridge topology PTMP (point to multi-point) where there are many clients are connected, and topology Bridge mode to PTP (point to point) where there is only one client is served. At this testing time, same station side - the same uses station-bridge mode.

From the results of testing there was no significant difference in throughput. When used to handle one client, throughput both still balanced, between 150Mbs up to 200Mbps up and
