How to Inject Epoxy

It is common practice when performing angled polishing of SM MPO to first perform a flat polish to remove epoxy. The purpose of this document is to provide guidance on control of MT ferrule epoxy injection to enable angle grinding without the need for flat polishing.

Importance of Jacket Crimping

Crimping or rather crimping strength is essential to the integrity and reliability of a patchcord. Poor crimping will lead mechanical failure and, thus, optical performance degradation or failure of the patchcord.

Avoid Over Polishing MT Ferrule & How to Control the MT Angle

To ensure consistence good insertion loss, and 3D geometry on the MT ferrule, it is very important to have good polishing process for the MT ferrule. When it comes to MT 8° angle ferrule polishing, it is more criterial because MT angle ferrule’s endface should have non-polished area (flat surface) and polished area (angle surface). As per the IEC 61754-7, maximum non-polished (flat area) allowed is 0.8mm in size (approximately 30% non-polished area) and there is no minimum non- polished area (flat surface) defined in the IEC 61754-7. Both the non-polished (flat) and polished area (angle area) surface sizes are needed to controlled in order to achieve good insertion loss.

It was, it still is but will it always be ‘the dirty connector’…?

One of the many hopes for network operators who deploy optical fiber has been, of course, its performance & reliability. Most if not all hope that the general maintenance requirement will be greatly reduced with the use of fiber optics as compared to conventional copper as optics does not rust, does not get affected by electromagnectic inteference and is water resistant.

Optical connectors must have no contamination prior to mating

What can happen when the optical end face is dirty? The beam of light may not be able to travel through the core. Optical connectors become contaminated from a variety of reasons. Usually 2-15 micron sized contaminants will have an impact on the signal transmission and could cause damage to the optical end face. The majority of network down time is caused by optical connector contamination.

MPO CONNECTOR POLARITY – TIA-568

Each MPO connector has a key on one side of the connector body. The “Key Up” position refers to the orientation where the key is located at the top position of the connector. When looking at the end face of the connector, position 1 is on the far left while position 12 is on the far right. For a 24 fiber MPO connector, the same orientation applies with the top row being positions 1 to 12 and the bottom row being positions 13 to 24. Depending on the adopted connectivity orientation, the MPO adapter needs to be suitable for its application, which is either “Key Up to Key Down” or “Key Up to Key Up”.

Data Center Boom Heats Up

Higher Data Center operational temperature affect fiber optic reliability

Big Data Analytics, The Cloud, Internet of Thing: The buzz words in the ICT (Information and Communications Technology) industry. All of which fuels the flourishing Data Centers market across the globe at an alarming rate. Cisco predicted that by 2018, more than three quarters (78%) of workloads will be processed by cloud data centers; 22 percent will be processed by traditional data centers. Although overall data center workloads will nearly double (1.9-fold) from 2013 to 2018; however, cloud workloads will nearly triple (2.9-fold) over the same period. The workload density (that is, workloads per physical server) for cloud data centers was 5.2 in 2013 and will grow to 7.5 by 2018
