What is PD IEC TR 62572‑4 about?
PD IEC TR 62572 is a series on fibre optic active components and devices. Active devices are electronic components made up of semiconductor materials that actively manipulate electrons to perform the intended function. PD IEC TR 62572‑4 is a Technical Report, that provides guidelines for optical connector end-face cleaning methods for receptacle style optical transceivers. PD IEC TR 62572‑4 includes details about handling receptacle style optical transceivers, internal structures of optical transceivers, information on cleaning tools and machines, applicable cleaning methods, and cleaning procedures.
Receptacle style optical transceivers, as well as optical fibre patch cords, are handled by operators and maintenance staff of optical network systems. PD IEC TR 62572‑4 can be used as a guideline to prepare instruction manuals for the operators and maintenance staff of optical network systems.
Who is PD IEC TR 62572‑4 for?
PD IEC TR 62572‑4 on fibre optic active components and devices is useful for:
- Telecommunication sectors
- Telecommunication equipment manufacturers
- Design engineers
- Quality control personnel
Why should you use PD IEC TR 62572‑4?
High-speed internet communication systems and subscriber systems have spread rapidly owing to the increased capacity of data communication. In these systems, receptacle style optical transceivers such as SFP (small form-factor pluggable) and XFP (10-Gbit/s small form-factor pluggable), which can be mounted and removed during transmission systems operation, are widely used.
PD IEC TR 62572‑4 discusses optical receptacles of optical transceivers, which are connected to optical connector plugs of optical patch cords, and optical signals are transmitted and received through these optical receptacles. Pluggable optical transceivers are typical of small size and low cost, and their designs are often simplified. Therefore, the internal structure, especially the receptacle structure, tends to vary between optical transceiver manufacturers.
Generally, to maintain the high reliability of optical connections, the optical connector end-face needs to be cleaned. PD IEC TR 62572‑4 is a technical report of optical connector plugs and optical adaptors, proposed by Japan, was published in August 2010, and revised in January 2016.
PD IEC TR 62572‑4 discusses multi-fibre connectors, like the multi-fibre push-on (MPO) connector that has been widely used in data centres as fibre-to-fibre connections since the early 2010s. They are now also used as optical interfaces in optical transceivers, such as QSFP (quad small form-factor pluggable) and CFP (C form-factor pluggable) transceivers.
Using PD IEC TR 62572‑4 you can understand the guidelines for optical connector end-face cleaning methods for receptacle style optical transceivers.
