Difference between managed and unmanaged fiber optic media converter

If you finally figured out what fiber cable type you need for you application and your ready for media converters you might of pumped your brakes when you noticed the same converter being offered as "managed" or "unmanaged" and now your asking yourself, what's the difference?

A unmanaged media converter allows for simple communication with one another but does not provide monitoring, fault detection and setting up network configurations. The unmanaged option is a great choice for newbies and if you want a plug and play fiber network cable installation.



Managed media converters are more costly but do offer additional network monitoring, fault detection, remote configuration and more. After reviewing the managed Signamax media converters we stock, one thing I noticed was it mentions SNMP management. There is no mention of SNMP for our unmanaged fiber optic media converters. What the heck is SNMP?

SNMP (Simple Network Management Protocol) is a standard for managing devices on IP networks. In common SNMP installations one or more administrative computers have the job of monitoring and managing a group of devices on a network. A software component called an agent will report information via SNMP to the manager.

A SNMP managed network consist of 3 key components.

* Managed device (Media Converter)
* Agent, software that runs on managed devices
* Network management systems (NSM) software that runs on the manager (Administrative computer)

So get the unmanaged if your a noob, get the mananged if your network has certain management demands.

How to convert HD-SDI to HDMI?

Many HD broadcasting cameras are pushing out a HD-SDI signal that needs to be viewed using a HDMI connection on the other end. You'll need a HD-SDI to HDMI convertor, these converters are compliant with the Society of Motion Picture and Television Engineers (SMPTE) standard of 292M and 296M. These standards support data rates up to 1.485 Gb/s.

Everfocus model number EHA-SRX is capable of receiving HD-SDI digital video signal up to 1920x1080 resolution over 75ohm coax cable. This converter will provide a complete solution for the transmission and display of both interlaced and progressive scan HD-SDI digital video. Yes Everfocus is a security camera manufacture but don't worry, this will work for your broadcasting cameras too!

Let's get a look at it from our YouTube Channel



Features:

* Accepts HD-SDI digital video at 720p/60, 1080i/60 and 1080p/30 formats/frame rates

* Processes HD-SDI standard SMPTE 292M and 296M at 1.4585 Gb/s data rate

* Provides standard HDMI output for HD TV monitor display

* Integrated cable equalizer for long distance video transmission without loss of quality

* Capable of receiving HD-CCTV digital video over 75ohm coax cable at distanced over 100 Meters

* High quality digital video and audio transmission with zero latency



Now let's dig into the cable transmission. The EHA-SRX allows a total signal attenuation of up to 43.56 dB along the cable between devices. The actual maximum cable length depends on the attenuation characteristic of the particular cable being used. So if you have a long coax run make sure you have a kick ass quality cable so you have a lower signal attenuation.



I feel like I nailed this blog post, reminded myself of Kirk Lazarus from Tropic Thunder "I don't read the scrip, the scrip reads me."
