Product Description

Portable Structure Design:


Ethernet Test with High Efficiency and High Convenience

GAO-ENET-101 Handheld Gigabit Ethernet Test Set fully meets RFC2544 standard, supports Throughput; Latency; Frame loss; and Back-to-Back test in metro network, and can be able to generate a complete test report.

BERT Test:

Ethernet BERT test adopts the similar principle of SDH BERT test. It is by transferring the Ethernet frames with special test code, then analyse these frames at the receiver to test the network.

Multi-Stream Test:

GAO-ENET-101 supports to generate multiple data streams to test the forward ability of these service in Ethernet network. In addition, multiple data streams can be set as a different priority.

Y.1564 New Standard for Ethernet Test (Optional):

RFC2544 was the most popular standard for Ethernet test. However, it is specially designed for indoor network facilities test, not suitable for outdoor field test. Hence, ITU-T Y.1564 is particularly introduced for telecom operator to do Ethernet network service launch and fault diagnosis. Compared with RFC2544, it includes critical SLA standards such as packet jitter identification and QoS measurements, which could increase test speed promptly, save test time and resource, and optimises QoS.

Network Configuration Test

Network configuration test will conduct a test for every service to verify whether the service configuration is correct or not and whether all specific KPI or SLA parameters have been satisfied.

Performance Test

When the configuration of every service has been checked and verified successfully, OTP6126 will conduct a test for the quality of service simultaneously.
