1.1 Technical Specifications
Ports Performance
When a port is operating at 100Mbps:
Data Rate: 100Mbps
When a port is operating at 10 Mbps:
Data Rate: 10 Mbps
Network Standards
100Mb: Ethernet IEEE 802.3u, 100BASE-TX, 100BASE-FX
10 Mb: Ethernet IEEE 802.3, 10BASE-T
Auto-sensing for speed: IEEE 802.3u
Packet-Processing Between Domains
Filter and Forward Rate from 100Mbps ports: 148,800 pps max
Filtering and Forwarding Rate from 10 Mbps ports: 14,880 pps max.
Processing type: Store and Forward, non-blocking
Auto-learning: 2K address table
Address buffer age-out time: 300 sec.
Packet buffers memory: 128KB, dynamically shared on all domains
Latency (not including packet time): 100 to 10 Mbps: 5µs
10 to 100Mbps: 15µs
Path Delay Value: 50 BT on all ports
LLL (Link-Loss-Learn): Factory default is activated on port 1 and 2 (allow to flush the internal address buffer,
and qualify to use with S-Ring and RSTP for faster recovery in ring topology)
Maximum Ethernet Segment (or Domain) Lengths
10BASE-T (Unshielded twisted pair) - 100 m (328 ft)
100BASE-TX (CAT 5 UTP) - 100 m (328 ft)
100BASE-FX, half-duplex: (multi-mode) - 412 m (1350 ft)
100BASE-FX, full-duplex: (multi-mode) - 2 km (6,562 ft)
100BASE-FX, half-duplex: (single-mode) - 412 m (1350 ft)
100BASE-FX, full-duplex: (single-mode) - 20 km (65,620 ft)
100BASE-FX, full-duplex: (single-mode, long reach) - 40 km (131,240 ft)
Port Connectors:
RJ-45 Ports: support 100BASE-TX and 10BASE-T with auto-cross (MDIX). They are shielded 8-pin female
connectors for shielded (STP) and unshielded (UTP) Cat 3, 4, 5 cables.
One Fiber optic port: On the DFG48044X Series it is 100Base-FX with a "fiber flavor" choice of multimode
SC, ST, LC or single mode SC, ST or LC connectors. (By default factory settings is at "Full" duplex on fiber
ports)
