Edwards 3X-FIB — fiber optic network motherboard for the EST3X panel, supporting a 64-panel EST3X network or a connection into an existing EST3 network.
An EST3X panel has no network until an option card is fitted, and Edwards notes every networked panel must carry one. This is the fiber version, an adapter plus an electronics card. One point matters before ordering: the card carries no optics. Single mode or multimode is set by which transceiver is fitted.
- Networks 64 EST3X panels or interfaces with an EST3 network
- Takes SMXLO2 or SMXHI2 (single mode) or MMXVR (multimode) transceivers
- Connectors follow the transceiver: Duplex SC for SMXLO2 and SMXHI2, ST for MMXVR
- Budget 15 dBm between interfaces for SMXLO2; 25 dBm max for SMXHI2
- 19.2 to 27.6 VDC, with terminals for a 24 VDC backup source
- Class A, B and X; network data to 38.4 kbps, digitized audio 327 kbps
- 32 to 120 °F; copper segment 5,000 ft (1,524 m) max
The one-character sibling is 3X-FIB8, which Edwards limits to eight EST3X nodes and to 3-SFS systems only, so it does not reach an EST3 network; 3X-NET is the RS485 copper option.
