1. What is an MT ferrule?
MT stands for mechanical transfer. The MT ferrule is a multi-fiber ferrule in which fiber alignment is dependent on the eccentricity and pitch of the fiber and alignment pin holes. The alignment is dictated by the alignment pins during mating.
The critical elements for fiber alignment are:
2. What is an MPO Connector?
MPO is the industry acronym for “multi-fiber push on.” The MPO-style connectors are most commonly defined by two different documents:
3. What is an MTP® connector?
The MTP connector is a high performance MPO connector with multiple engineered product enhancements to improve optical and mechanical performance when compared to generic MPO connectors.
The MTP connector is in complete compliance with all MPO connector standards including the TIA-604-5 FOCIS 5, IEC 61754-7-1 and IEC 61754-7-2. The MTP connector is intermateable with all generic MPO-style connectors that are compliant to these industry standards. Generic MPO connectors are limited in performance and are not able to offer the high performance levels of the US Conec MTP connector.
4. Is the MTP® connector an MPO connector?
Yes. The MTP® connector is a high performance MPO connector engineered for better mechanical and optical performance.
5. What makes the MTP® connector superior to generic MPO connectors?
The MTP® connector has features and benefits that are not available on generic MPO connectors. Some of the key distinctions include:

6. What performance should I expect from my MTP® connector?
The chart in the MT Ferrules section of our product catalog, lists the Insertion Loss (IL) and Return Loss (RL) performance you should expect for each ferrule grade. However, improper use or termination can degrade these values. MTP® performance is primarily driven by three factors:

7. How many times can I mate/demate an MTP® connector and still maintain performance?
The US Conec MTP® connector is designed to exceed the TIA-568.3 specification of 500 mate/demates, the most stringent durability requirement in the industry. Under normal use and proper cleaning, MTP® connectors can survive well over 1000 mate/demates. The “critical elements” of our component designs enable such performance (see FAQ: What is an MT ferrule?). It is a best practice to inspect and clean, if necessary, before every mating. Failing to do so can result in fiber damage, ferrule damage, or debris build-up inside the guide pin holes. All of which impact connector performance.
8. What is the best way to clean connectors with MT ferrules including the MTP® connector?
The best method available for cleaning MT ferrules is the use of an advanced dry cloth cleaning system like the NTT-AT OPTIPOP and the US Conec IBC™ family of cleaners. The anti-static cleaning cloths that are used in both series of dry cleaners are designed to remove contaminants such as dust and oils that can come into contact with the ferrule and negatively impact optical performance.
The dry cleaning solutions offered by US Conec are designed and tested for single pass cleaning and will not leave a residue like alcohol based systems or simply shift the contaminants towards the outer edges of the ferrule like low-grade cleaning clothes and swabs with limited or no anti-static properties.
The OPTIPOP and IBC family of cleaners are designed for use with both male and female connectors and have options for single fiber, ceramic ferrule connectors. The IBC™ cleaners have been designed to work for cleaning connectors residing in the adapter.
The OPTIPOP cassette and card cleaners allow the owner to refill the cleaning cloths which can reduce cost per cleaning below traditional cleaning methods.
9. Is there intellectual property associated with the MT end-face geometry that I should be aware of?
Yes. US Conec offers a Label License to our customers.
10. What temperature range can MTP® connectors operate?
US Conec performs an extensive array of environmental and mechanical testing on all of our connector products. For Operational & Non-Operational (i.e. Storage) temperature performance, our test regimen includes:
