MII-VST / MII-VS15 / MII-VSA20 / MII-VSB20
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 ber ports (SC/ST/single SC ber connectors)
● Store-and-Forward technology for abnormal packet ltering
● For establishing ber 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
you must connect MII-VSA20 in one end and another
MII-VSB20, for example, in the other end.
