Huawei Optix 155/622H Metro1000 is a Huawei optical transmission equipment, originally called 155/622H, the group road is 155Mbit/s optical port or 622Mbit/s optical port. The branch circuit is a 2Mbit/s electrical port or a 10M/100M RJ45-type network port. The device does not support 10Gbit/s optical ports.

Higher than its level is the Huawei Optix metro3000, originally called Optix 2500 +, the maximum rate of the group road to support 2.5Gbit / s optical port, is modeled after Lucent 's ADM16/1 equipment, the technology is quite mature, the network is running a lot.

Lower than its level is the Huawei Optix metro100, Optix metro500 is mainly used in banks, tax and other business halls and ATM (automated teller machine) access services.

This equipment is very simple, generally installed directly in the small machine room in the integrated cabinet, integrated cabinet is generally 600mm (width ) * 300mm (depth) * 2000mm (height, according to the machine room alignment frame height varies slightly) of the cabinet, which has a rack top DC power distribution switch (open), there is a DDF (Digital Distribution Frame) terminal board, there is an ODF (Optical Fiber Distribution Frame, including the fusion fiber tray) sub-shelves According to the actual situation, there is also FE-DDF (Ethernet digital distribution frame). The top-of-rack power supply of the integrated cabinet is led directly from the header cabinet or switching power supply in the server room. When installing the metro 1000, it is directly installed in the integrated cabinet, and then a main (working ground, -48V ), a standby (working ground, -48V ) and a protective ground are connected to a total of five power lines from the integrated cabinet top-of-rack power module. Then it will be a branch of the business board on the 2M line lead to the comprehensive cabinet on the DDF terminal board, 10M/100M network cable lead to the FE-DDF, the four group road pigtail (east and west to each a group road optical port, each optical port including a receiving and sending two pigtails) lead to the ODF sub-frame to the outside optical cable, so that the completion of the hardware installation work. The next step is to add power to the equipment tuning test.
