GL-OCH04 High-performance cassette OCH
Content:

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:

Ø Provide high-density OCH ports, the whole machine can support 256 MDU terminals in full configuration, which has a larger capacity than ordinary box OCH. Each OCH port supports a split ratio of 1:64 (access to 64 MDUs), hot-swappable OCH optical module design, and supports a maximum transmission distance of 20Km;

Ø Support OCH fiber redundancy protection, link automatic protection switching when the fiber fails;

Ø Comprehensive OCH business capabilities, support dynamic bandwidth allocation DBA algorithm, dynamic bandwidth allocation mechanism (DBA) enables all users to share 1Gbps bandwidth more reasonably, and achieve reliable service quality;

Ø Support rich Ethernet functions, with effective isolation guarantee mechanism, VLAN isolation, port protection, MAC address binding, IP address binding, port speed limit, queue technology, flow control technology, etc., which play a role in the development of multi-service integration Technical Support;

Ø Complete security protection mechanism, using hardware-based packet-by-packet forwarding, can effectively detect and filter characteristic packets, support MAC address-based ARP attack automatic protection and automatic user blocking functions to prevent protocol packet attacks. Support various device protection functions such as DDoS, CPU overcurrent protection and VRRP to prevent illegal or abnormal traffic from entering the network, resist multiple virus attacks, and ensure the security of device management;

Ø Rich business functions, fully supporting the second-tier business functions. Realize advanced functions such as flexible QinQ and QoS, ACL supports L2~L7 in-depth IP message header 80-byte message filtering, providing high-quality QoS service quality guarantee for multi-service operation;

Ø Highly centralized operation management and maintenance, business-oriented, providing unified network transmission and interconnection protocols, address management, domain name management, security management, user access management, etc. Abundant OAM functions, including configuration, alarm, performance monitoring, fault isolation and safety management, etc.
