Model 2851
Ethernet BNC Coax to Fiber Optic Transceiver
- Supports 10Base - FL and FOIRL and IEEE 802.3 Standards
- Link Status, Collision, Receive Data, Transmit Data, and Power LED indicators
- ST or SMA optical connectors
- Connects directly to STP cable devices
- Multimode or Single mode option
S.I.Tech 2851 Ethernet Fiber Optic Transceiver is designed to extend
the distance of Ethernet based coax LAN's on fiber cable up to 10 km.
The Transceiver has a BNC connector allowing easy connection to the
coax network and provides ST or SMA fiber optic connectors.
Five LED indicators provide a visible verification of transmission status
and transceiver functions.
