The conclusion of the 100G upgrade review between East China computer rooms has been solidified into a standard: cutover projects are shipped with a pre-packaged spare parts package, and double shifts of operation and verification are implemented on site to reduce waiting for parts in the window, rework, and fatigue operations.

The 100G optical fiber interconnection upgrade between buildings in a large data center in East China was all completed within a 15-minute window, and the business was not affected. This article reviews how to remove the cutover window and how to retain the rollback, and provides replicable methods for non-stop transformation of the computer room.

EB-LINK recently announced four investments in the next phase at a product line review meeting: complete high-speed product line, spot pool expansion, code library update and test process upgrade, all centered on the existing needs of data centers, security, power and other industries.

After reviewing the product line, EB-LINK clarified the direction of resource investment in the fourth quarter: it will continue to focus on the production line testing capabilities and ready-made products, and model expansion will only be carried out along the main lines of optical communication and optical fiber connections. This article explains three specific things that this business philosophy implemented on the production line.

The EB-LINK optical module custom coding station has recently been expanded and put into use. Batch coding, readback verification, and actual insertion and sampling are split into three independent processes. The code library simultaneously covers more new switch models, and the pace of customized batches from proofing to batch shipment is further tightened.

Starting from fiber optic transceivers in 2008, EB-LINK now sells 282 models covering eight categories on the site. EB-LINK's product lineage extends all the way along the customer link. This article summarizes the judgment logic behind this evolution: each additional model corresponds to a link that has been actually delivered.

EB-LINK has upgraded the after-sales acceptance files. The factory test data and coding pattern records of faulty parts can be retrieved one by one based on the product label batch number. Customers can prepare the information according to the list when submitting for repair, and the demarcation and processing cycle is shortened.

A certain park monitoring capacity expansion project followed the EB-LINK service process to complete selection consultation, free coding, sample verification, and unit-by-unit testing and delivery. It took about two weeks from submission of the link list to the delivery of the complete set of goods. After arrival, it was put on the shelves according to the corresponding table for retesting.

EB-LINK divides the working day technical support response into three sections: acceptance, delimitation, and plan, and clarifies the actions and connection methods of each section. Issues submitted during working hours will be accepted on the same day, and messages during non-working hours will be processed according to the queue.

From model selection consultation to after-sales repair, EB-LINK divides customer service into four links: consultation, free coding, one-by-one test delivery, and working day response. It also publishes a process list, explaining what customers need to provide, what they can get, and who to contact for follow-up in each link.
