GL-OCH04 is a box-type OCH switching equipment developed by Guanlian Communication. It provides 4 OCH interfaces, 8 10/100/1000 base-T interfaces, 4 10G base-SR/LR/ER interfaces, and the height is only 1U. Easy installation and maintenance, saving space. The OCH adopts advanced technology in the industry, has powerful functions and QoS guarantees in Ethernet services, and supports SLA and DBA. The split ratio is as high as 1:64, and it supports mixed networking of different types of MDUs, minimizing the operator's investment.
Features:
OCH: The OCH complies with IEEE802.3ah and the communication industry standard of the People's Republic of China (YD/T 1475-2006).
System capacity: OCH04 single OCH port supports the access capability of 64 terminals, and the whole machine can support 256 MDU terminals under full configuration.
Upper connection port: Flexible design supports a variety of combinations of different types of metropolitan area networks. Choose optical or electrical ports according to network conditions.
Equipment size: 1U equipment occupies less space in the computer room, consumes less power, and reduces business operating costs.
High reliability guarantee, support dual power supply.
Product Features:
