Bộ chuyển đổi 8 kênh E1, 4 Ethernet PDH sang quang Humanity RPM-150S8EN
RPM-150S8EN: PDH is the point to point fiber transmitted device based on the SLSI. It realizes 8E1 and one 100M Ethernet over fiber. The integrated rate is high, the power consumption is low, the capability is steady and easy to use.
- The device have 4 Ethernet port ,it can setup whether isolation or not isolate for every Ethernet through on-off setting.
- Fiber circuitry speed is 150Mbps.
- E1 port code is HDB3,E1 dithering ,transfer speciality, export dithering according to ITU-T G.703、G823 and G.742
- Ethernet port ,supports auto-negotiation for 10M/100M and half/full duplex working mode.
- Self-contained alarm function ,can inspect the real time estate of terminal device.
- As the far-ending device ,can be combined to star-net with rack devices
- Supplies RS232 network manage port.
- Supplies one customer RS232 data channel.
- Single board design, 1U, and 19 Inch standard.
