The BTR fibre optic connection unit type 1501197G02HC is a compact and universally applicable unit for integration into existing network infrastructures. It serves as a connection point for fibre optic cables in the singlemode range and is designed for mounting on recessed or hollow wall outlets, as well as for surface or rail mounting. The unit is equipped with LC duplex connectors with laser shutter and singlemode pigtails, specifically designed for connection with FITH cables containing singlemode fibres. The pigtails consist of singlemode fibre OS2 with a core diameter of 9 µm and a cladding diameter of 125 µm, in accordance with standards IEC 60793-2-50 B.1.3 and B.6_a. The fibre is bend-insensitive according to ITU-T G.657.A1 and compatible with ITU-T G.652.D, enabling flexible installation even with small bending radii.

Applications

The connection unit is suitable for use in structured cabling systems in office buildings, industrial facilities, hospitals or other institutions where a reliable fibre optic connection is required. It is particularly suitable for integration into existing networks where flexible mounting on various substrates is necessary. The unit can be used both indoors and in protected outdoor areas, as it features a robust construction and is designed for use in various environments.

Functions and equipment in detail

The unit offers multiple cable entry options: rear, top, bottom, left or right, enabling flexible installation at different positions. Unused openings are sealed with blind plugs to ensure clean and secure cabling. The splice cassette is swivelling and removable, providing space for up to 8 crimp splice protectors, enabling efficient and organised cabling. The unit's cover is removable without tools, simplifying maintenance and inspection of connections. The insertion angle is 90°, allowing compact placement on walls or in enclosures.

Technology explained simply

The integrated clips allow mounting on rails in two directions, facilitating installation in various enclosure configurations. The LC duplex connectors with laser shutter ensure a secure and interference-free connection, especially when using lasers in fibre optic communication. The pigtails are equipped with singlemode fibre OS2, suitable for high transmission rates and long distances. The bend-insensitive fibre according to ITU-T G.657.A1 allows installations with smaller bending radii, which is advantageous when cabling in confined spaces or when used on rails.

Compatibility and accessories

The connection unit is compatible with FITH cables containing singlemode fibres. Suitable accessories include crimp splice protectors (item 15090401-E, 12 pieces) and splice protector holders for 6 crimps (item 15090304-I), which can be used for secure and orderly cabling of splice points. The unit is available in various variants, including with SC APC, SC UPC, LC-D APC or LC-D UPC connectors, as well as in Grade B. The colour of the cover parts is pure white RAL 9010, enabling visual harmonisation with other devices in the network.

Mounting and installation

Mounting is done either on recessed or hollow wall outlets, or using integrated clips on rails. The tool-free removal of the cover simplifies installation and maintenance. The multiple cable entry options allow flexible placement of the unit, regardless of cable feed position. The splice cassette is removable and swivelling, facilitating work at the splice point.

Advantages in operation

The unit offers a compact design with high functionality. The tool-free removal of the cover and the swivelling splice cassette reduce maintenance effort. The use of bend-insensitive fibre and integrated clips for rail mounting increases installation flexibility. The blind plugs for unused openings ensure orderly and secure cabling that remains stable over time. The pure white RAL 9010 colour supports visual integration into existing systems.
