Recently, EB-LINK completed testing and shipped a batch of 10G optical modules and network cards prepared for the imaging department of a tertiary hospital. It is used to upgrade the imaging channel from the radiology department to the information center from Gigabit to 10G, and alleviate the queuing of thin-slice CT during the peak outpatient upload.

Only two sections of the link will be affected during the renovation, and the construction will be carried out during the night window.

The information department of the hospital did not want to make major changes to the equipment at first. After actual testing, it was found that the waiting time for access during the day was mainly due to congestion on the upload channel, not the storage itself. The plan retains the original access switch and only replaces the image server to aggregation and aggregation to image storage sections with 10G. The construction is scheduled after 22:00 on working days. Module replacement and jumper arrangement are completed in one night, and retest time is allowed before the morning rush hour the next day.

Write the code according to the brand of the current network switch, and the modules and jumpers are supplied in the same batch.

The switches in the hospital are stock brand equipment, and the modules are delivered after being written with the corresponding brand code to avoid unrecognized ports when plugged in. For short links in the buildingSFP+ 10G multi-mode dual-fiber optical module paired with LC-LC 10G multi-mode OM3 two-core jumper, the link spanning about 2 kilometers between two buildings takes single mode, chooseSFP+ 10G single-mode dual-fiber 10km optical module, the server side network card is selected according to the motherboard slot margin.

Do three things before putting the goods on the shelves

• Check the wavelength and end face type. 850nm multimode is only used for short jumpers in the building. For single-mode links, confirm that the directions of both ends of the LC dual core are consistent;
• Use an optical power meter to measure the light absorption direction by direction, and ensure that it falls within the nominal range of the module and leaves a 3dB margin;
• After the two ends negotiate to reach 10G full-duplex, they copy a large file and record the actual throughput and error packet count.

This batch of modules and network cards have been shipped according to the same link account, and subsequent image storage expansion can be renewed accordingly. The hospital information department needs to check the port and wavelength. You can dial 0755-83179002.
