The AN-102-X3X1 is an Optical fiber switch / Multiport FX media converter that offers 2 port 10/100Base-FX optical and 1 port 10/100Base-Tx Copper. It supports both Single optical fiber and dual optical fiber, its transmission distance ranges from 2km to 120km. This optical fiber switch works under both Half and full-duplex mode. It supports the STAR network topology and it is an ideal option for fiber to home (FTTH) optical fiber solution, city optical fiber networks,etc.
Dual port fiber media converters can be used, in networks, where dual fiber ports and 1 TX port can be used - in redundunt applications, for military objects etc.
Another application, how you can use the converter is to make a chain network of several offices that should be connected to on central network, and the middle office should have a twisted pair connection as well. AN-102-X3X1 the application, what is similar to SDH add drop ring methodology, just ring is not closed. Fiber ports can be choosen at your choice - dual fiber optical modules at 20 - 120 km, multimode 2 km, or WDM 20 - 40 km single fiber BiDi. |
