Gl-e8608t-atg 10 megapixel cartridge with 8 megapixel OLT

Product Overview:

Gl-e8608t-atg is a box OLT switching device independently developed by CoCOM, which provides 8 EPON OLT interfaces, 8 10/100/1000 Base-T interfaces and 4 10G Base-SR/LR/ER interfaces, with a height of only 1U, easy installation and maintenance, and space saving. The OLT adopts industry advanced technology, has powerful function and QoS guarantee on Ethernet service, and supports SLA and DBA. With a spectrophotometric ratio of up to 1:64, the investment of supporting different operators is minimized.

Product Features:

EPON: The OLT complies with IEEE 802.3AH and the Communications industry standard of the People's Republic of China (YD/T 1475-2006).

System capacity :GL-E8608T-ATG single PON port supports up to 64 terminals access capacity, the whole machine can support 512 ONU terminals under full configuration.

Upper port: flexible design supports a variety of different man interface types combination, according to the network situation to choose optical port or electrical port.

Equipment size: 1U equipment occupies less room space, consumes less power, and reduces business operation cost.

High reliability guarantee, support dual power supply.

Product features:

Ø provide high density of PON mouth, full match can support 512 ONU terminal, larger than ordinary cassette OLT capacity. Each PON port supports a 1:64 beam splitting ratio (with a maximum access of 64 ONU), and thermally unplugged PON optical module design, with a maximum transmission distance of 20Km.

Ø support redundant protection, PON optical fiber in optical fiber failure link automatic protection switching;

PON Ø comprehensive business ability, DBA support dynamic bandwidth allocation algorithm, mechanism of dynamic bandwidth allocation (DBA) that all users can more reasonably share 1 GBPS bandwidth, realize the reliable service quality;

Ø support rich Ethernet function, with the effective isolation guarantee mechanism, VLAN isolation, protecting the port, IP address, MAC address binding binding, port speed, queue technology, flow control technology such as the development of multiple business integration technical support;

Ø perfect safety protection mechanism, one by one based on hardware packet forwarding, can be effective in view of the characteristics of packet detection and filtering, support the ARP attack based on MAC address automatic protection and automatic block function, prevent protocol message attack. Support various device protection functions such as anti-DDOS, CPU overcurrent protection and VRRP, prevent illegal or abnormal traffic from entering the network, resist various virus attacks, and ensure the safety of device management;

Ø business function is rich, fully support business functions on the second floor. Flexible QinQ and QoS and other advanced functions are realized. ACL supports Message filtering of L2 ~ L7 deep into the header of IP message with 80 bytes, providing high-quality QoS service quality guarantee for multi-service operation.

Highly centralized operation management and maintenance, business-oriented, provide unified network transmission and interconnection protocol, address management, domain name management, security management, user access management, etc. Rich OAM features, including configuration, alerting, performance monitoring, fault isolation, and security management.
