19” LC module
Modular design is a convenient solution when you don’t want to acquire preassembled cable with 48 or 96 fibers for 19” panel. Modular structure allows you to complement the panel in four phases according to needs.
Modular structure includes 19” frame and preassembled modules. The cable used in the modules is user-friendly FTMSU cable with small diameter.
With regular modules, the cable is preassembled on both ends. But if there is a difficult inlet, then the other module can be left uninstalled.
In the table belew, you can see the product codes, names and lengths for the frame and modules. Other lengths are available on request. Clicking the product code numbers will take you to the product page on the Finnish STK service and clicking the product name will open a picture of the product.

There is a new version of the frame which is not as deep as the regular version. The new version has its own fitting modules as well. In the modules, the cable is at an angle of 45⁰ relative to the front edge. This saves space and the modules can also easily fit in cross-connection cabinets without the cable being unnecessary bent. The cable can be installed in the module so that the cable goes either left or right. The frame also has holes for wall mounting.
When talking about MTP and MPO connectors we need to keep in mind that they are not the same although compatible.
MTP is developed out of MPO, but with better quality. There are many companies manufacturing parts for MPO connectors, but only US Conec manufactures parts for MTP connectors. This means that parts for MPO, for example the boot, housing and ferrules can be manufactured by anyone. And if the connector is called MTP, then all parts are manufactured by US Conec.
Benefits of MTP over MPO
Detachable housing. Enables repolishment of the ferrule
Floating ferrule. Improves the connection of the connector surfaces
The manufacturing tolerances of the control pins in the male connectors are tighter
The spring of the connector is better centered and its compression force is better
There are two types of MTP/MPO connectors, male and female. In the male connector there are guide pins and in the female connectors corresponding openings. The male connector is used among other things inside panels and in device interfaces. The female connector is commonly used in patch cords and in instrument and trunk cables.
MTP/MPO connectors are available with 8, 12 or 24 fibers. The connector is the same size with all the fiber counts. In connectors, with 8 or 12 fibers, there are 12 places for fibers. When using 8 fibers the 4 middle places remain unused. This 8-fiber connector is mainly used only in multimode products and in 40Gb systems.
In 24-fiber connector the fibers are in two rows
12-fiber connector is the most common at the moment. 24-fiber connectors advantage is greater coupling density, which leads to halving the trunk cables needed. The challenges for using 24-fiber connectors is their manufacturing complexity, which raises their price considerably.
The insertion loss for MTP/MPO connectors is typically little higher compared to SC and LC connectors with ceramic ferrules, typically 0,25dB. Return loss is also weaker compared to regular ferrules. Therefore SM MTP/MPO connectors are almost always APC polished, and that enables them to reach the typical value of 55dB for return loss.
Panels and modules
Several different options are available. There are panels, where at back there are slots for 2 to 16 MTP/MPO adapters. The panel in question can be seen below, photographed from behind. In front of the panel there are slots for LC quattro adapters or for MTP/MPO adapters. When using MTP/MPO connectors, 1U panel can reach as many as 384 connections. In this case there are MTP/MPO connectors in front of the panel as well. The attached picture shows the panel in question from the back.
In a traditional module there are two slots for MTP/MPO connectors at the back and 24 slots for LC connectors in front. Four of these modules can be fitted into 1U panel. Modules can be added when needed. Inside these modules, there are two short MTP/MPO-LC patch cords fitted inside.
Due to large quantity of different options for modules, we are not able to provide all information here. Please contact us for additional information.
