Summary: If you know you only need 10/100, buy these. They are a great value for money.
Pros: These units are easy to unpack, mount, and power. If you don't know the providence of the fibre optic cabling that you are using they can be a tad difficult to get that first connection going. If you know which strands go where and they are appropriately color coded, then these units can be out of the box and running in less than five minutes!
Cons: None that I have found so far. We currently employ 20 of them to run 6 out buildings.
Summary: These replaced a 10BaseT pair of TRENDnet fiber converters after significant speed improvements; the prior pair had been in operation for over half a decade, also without any problems. I put my Internet cablemodem/DSL modem, one APC UPS, and one fiber transciever together on one side of the house, and use these to optically isolate the rest of my network; any surge coming through the WAN link to my internet provider (say, a lightning strike) can at most wipe out the...
Pros: I've had a pair running with a 30 meter fiber cable for about 18 months without more than a couple hours of downtime; no problems, no issues. Any of the rare network issues I have are _not_ related to these; my firewall apparently needs a reboot about once a year, and the cable-modem about twice a year.
Summary: I have 6 of these linking up various houses for a property I maintain with CCTV cameras. The cameras a 3 megapixel running a full 15fps, so, these media converters are getting slammed 24/7. Haven't had to power cycle a single one. One of them is in an unheated pole barn and it's about 14F now, wondering if it will make it over the winter? I rolled the dice for now, as I have a spare.
Pros: No switches to set, just plug and play
Cons: Wish they made a hardened version for cold environs
Summary: I have used half a dozen of these for almost five years, and unlike a lot of others, I have _never_ had to reset these, and I have never had any problems with them, whatsoever. Even the Cisco switches they are attached to cannot be spoken for in that manner.
Pros: - Absolutely no maintenance; reliable. - Same unit as discrete or used in rack chassis.
Pros: I've had a pair of these running for over a year and not one hiccup. One is in a non air conditioned steel building providing a link to a radio tower. Last summer we had temps over 107 degrees a few days and no problems. I had another brand of converter die recently in a much milder climate. I replaced both with two more of these.
