The article 150M1AO0020E8 from Btr Blumberger is a Pigtail with ST-connector for multimode fibre of category OM3. It serves as a connecting element in the field of fibre optic communication, particularly in networks that transmit high data rates over short to medium distances. The cable is equipped with a connector on one side and has a length of 2.0 metres. It is designed for use in structured cabling systems, where a reliable and precise optical connection is required.

Applications

The Pigtail is typically used in the field of fibre communication, for example, to connect fibre optic cables with network devices, switches or other optical components. Due to the OM3 specification, it is suitable for high-speed applications such as Gigabit- or 10-Gigabit-Ethernet. Use in structured cabling systems, particularly in data centres, office buildings or industrial environments, is common. The bend-insensitive fibre according to IEC 60793-2-10 Type A1a.2 allows flexible installation without risk of breakage or performance loss due to bending.

Functions and Equipment in Detail

The cable features a multimode fibre OM3 with a core diameter of 50 µm and a cladding diameter of 125 µm. The fibre is bend-insensitive, offering higher mechanical robustness and reduced sensitivity to bending losses. The connector is an ST-connector according to IEC 61754-2, ensuring a secure and repeatable connection. The cable construction includes a compact conductor with a diameter of 0.9 mm, enabling compact and flexible handling. The colour sequence in the set corresponds to the standard IEC 60304 and includes the colours red, green, blue, yellow, white, grey, brown, violet, turquoise, black, orange and pink. Secondary and primary coatings are colour-matched, which simplifies identification and assignment in cable management.

Technology Explained Simply

The designation OM3 refers to a multimode fibre optimised for light signal transmission at 850 nm and offering a bandwidth of at least 2000 MHz·km. This makes it particularly suitable for high-speed applications. The ST-connector is a mechanical plug with a ceramic or glass fibre insert, which is inserted into a socket. The connection is secured by a screw lock, ensuring a stable and durable connection. The bend-insensitive fibre according to IEC 60793-2-10 Type A1a.2 is specifically designed for applications where the cable is frequently bent or installed in tight radii without impairing optical performance. The length of 2.0 m is a standard length sufficient for many installation scenarios, eliminating the need for additional extensions.

Compatibility and Accessories

The Pigtail is compatible with all devices that support an ST-connector and are designed for multimode fibre OM3. It can be used in conjunction with other components such as fibre cables, patch cables or network devices. The colour sequence according to IEC 60304 enables uniform identification in cable management, simplifying maintenance and fault diagnosis. The cables can be individually configured using a cable configurator, allowing adaptation to specific requirements.

Installation and Mounting

Installation is performed by inserting the ST-connector into the corresponding socket of the device. The connection is secured by turning the screw lock. The bend-insensitive fibre allows flexible routing, even in tight radii, without impairing optical performance. The cables are pre-equipped with a connector, so no additional assembly is required. The length of 2.0 m provides sufficient slack for connections between devices and cable junctions.

Advantages in Operation

The Pigtail provides a reliable and stable optical connection with low losses. The 100 % testing of insertion loss and return loss ensures high quality and reliability. The colour-matched coatings simplify identification and management in the cable system. The bend-insensitive fibre reduces the risk of breakage and performance loss during bending, increasing service life and reliability. The standard length of 2.0 m is suitable for many application scenarios and reduces the need for additional extensions or adapters.
