RS-232 Fiber Optic Micromodem (M82xxD) Review:
Jim Atkins
4.0 out of 5 stars
July 19, 2023 M720DA Delivers Versatile Fiber Integration For the past few months, I've relied on VERSITRON's M720DA Multimode to Singlemode Media Converter. I must say, it has not only exceeded my expectations, but has also been a worthy investment so far. We are in expansion phase, our team has been considering different types of fibers, and this converter has been the best. What impressed me was its low power consumption, ensuring efficiency without compromising performance. Its full wire-speed performance and SFP flexibility assures versatile performance. The LEDs on the media converter add a practical touch and helps simplify its troubleshooting and maintenance. Our experience with this converter has been amazing! There has been no single instance of weak signal since installation.
Another aspect that caught my attention was the ease of modem installation. Upon consulting with the VERSITRON team, I learned that the modem can be used to support Interface Extenders (DCE-DTE) and modem links (DCE-DCE). This flexibility is truly amazing. Performance, data rate capabilities, temperature range, and ease of installation are some features that make it a highly commendable product in my opinion. You can take my words and consider this reliable micromodem to meet your connectivity needs.
