Here is the parameter introduction of EDS-308-SS-SC:
Port Configuration
Port Type: 10/100BaseT(X)/FX1.
Port Quantity: 8 ports, including 6 RJ45 - interface 10/100BaseT(X) ports and 2 single - mode SC - interface 100BaseFX ports4.
Network Standards4: It complies with IEEE 802.3 for 10BaseT, IEEE 802.3u for 100BaseT(X) and 100BaseFX, and IEEE 802.3x for flow control.
Switch Properties
MAC Table Size: 2 kbits.
Packet Buffer Size: 768 k.
Processing Type: Store - and - forward.
Ring Redundancy and VLAN1: It has no ring redundancy and supports VLAN function.
Management and Alarm Functions1: It has no network management function. The alarm function is realized by a relay, which can send out warnings for power failure and port break alarm.
Optical Fiber Parameters
Fiber Cable Type: For 100BaseFX, it supports multi - mode OM1 50/125 µm fiber and single - mode G.652 fiber.
Typical Transmission Distance: Multi - mode fiber is 4 km, and single - mode fiber is 40 km or 80 km.
Wavelength: TX wavelength range is 1260 - 1360 nm for multi - mode, 1280 - 1340 nm for 40 - km single - mode, and 1530 - 1570 nm for 80 - km single - mode. RX wavelength range is 1100 - 1600 nm for all.
Optical Power: TX power range is - 10 to - 20 dBm for multi - mode, 0 to - 5 dBm for single - mode. RX sensitivity range is - 3 to - 32 dBm for multi - mode, - 3 to - 34 dBm for single - mode. The link budget is 12 dB for multi - mode and 29 dB for single - mode. The dispersion penalty is 3 dB for multi - mode and 1 dB for single - mode.
Power Parameters
Input Current: 0.15 A @ 24 VDC.
