Usage

SyncE from Fibersystem is intended for interfacing substation tele protection equipment with IEEE C37.94 interfaces to a synchronous ethernet network. The two IEEE C37.94 ports can be used separately or in parallel.

The housing 19” rack mounting is standard compliant for power substation installation and can be equipped with two removable power supplies for redundancy, from 48VDC or 230VAC.

Fibersystem products for substation use is built for demanding environments and can withstand 4kV bursts.

IEEE C37.94

Fiber optic interface according to standard “IEEE C37.94-2002, IEEE Standard for N times 64 Kilobit per second”. C37.94 is transparent to protocols and signalling – All data slots are transferred. Both are transparently converted into UDP packets and back.

E1 describes a galvanic G.703 interface with G.704 frames at 2048 kbps commonly used in telecommunication.

Typical application areas

Substation environment – Differential Relay protection over Ethernet networks
Industrial communication
Clock synchronisation
Telecom
Broadcasting
