Figure 1. 1-Port 100Base-FX (SC, Multi-mode) Module Front View

Features:

●Comply with IEEE 802.3u, 100Base-FX Fast Ethernet standard

●1 x 100Base-FX fiber ports (SC/ST/single SC fiber connectors)

●Store-and-Forward technology for abnormal packet filtering

●For establishing fiber link with cable length up to 2km (Multi-mode module) and 15/20km (Single-mode module) or 412m (half-duplex mode)

●Slide switch for Half /Full-Duplex selection (default in full-duplex)

●Plug and Play Installation

	1.	The fiber connector and distance support will be
		different by various models.
	2.	The MII-VSA20/VSB20 should runs in pair. It means
Note		you must connect MII-VSA20 in one end and another
Note		MII-VSB20, for example, in the other end.
		MII-VSB20, for example, in the other end.
