Optical Module End Face Inspection Standards
To provide a consistent inspection methodology, the International Electrotechnical Commission (IEC) published IEC 61300-3-35, which specifies quantitative acceptance criteria for debris, scratches, and defects observed during visual inspection of fiber optic connector end faces. 📦 For purchasing, use the RP Photonics Buyer's Guide for fiber endface inspection. What is fiber endface inspection?Optical Fiber infrastructures are increasingly common in government, military, business, and industrial applications. This increased deployment of optical fiber networks, and the need for reliable high bandwidth makes the simple task of checking and inspecting connector end-faces a crucial process. It's crucial to inspect, clean, and reinspect fiber end faces before mating connectors — whether on patch cords and trunks within the network or on the test reference cord you connect to your tester. We also offer two scanning white-light interferometers (SWLI) that enable.

How are the optical module and RRU connected
The Remote Radio Head (RRH) architecture consists of a baseband unit (BBU) and a remote radio unit (RRU). Both the BBU and RRU are connected using fiber optic cables to transport digital data and control information. The base station can be divided into two modules: the RRU for transmitting signals and the BBU for processing signals. It also provides checklists as reference. In this document, eRRU3232 is used as an example. Difference in installation and operation of other eRRU products are also described.
