The MTP optical fibre connector’s innovative floating internal ferrule ensures continuous contact between mated ferrules, even under stress. Moreover, its spring design optimizes clearance for ribbon fibres, safeguarding against damage in high-density applications.
The Emergence of 10G and Beyond
Optic fibre 10G transmission systems are gaining widespread acceptance, with clear migration paths to 40G and 100G already defined for fibre optic deployment. The IEEE 802.3ba 40G/100G Ethernet standard provides a roadmap for multimode fibre transmission, with OM3 and OM4 multimode fibres being the standard bearers.
Parallel Optics: The Data Centre’s Transmission Choice
Parallel optics technology has emerged as the preferred transmission method in many data centres and research labs due to its ability to support 10G, 40G, and 100G transmission effortlessly. To harness the full potential of parallel optics, the correct choice of cable and connector is paramount.
Parallel Optic Interfaces: A Quantum Leap in Data Transmission
Parallel optic interfaces differ significantly from traditional fibre optic communication by simultaneously transmitting and receiving data over multiple fibres. In contrast, traditional (serial) optical communication relies on a single transmitter and receiver at each end of the link. Parallel optical communication, however, employs multiple transmitters and receivers, distributing the data stream across several fibres. This approach allows for the operation of a parallel optics transceiver, which can aggregate signals from multiple lower-rate transmitters to achieve higher overall data rates. This method utilizes a ribbon cable design, with fibres aligned in a straight array, available in either 12-fibre or 24-fibre configurations.
The Crucial Role of Physical Connection Interfaces
Beyond cable performance, the choice of physical connection interface is equally important. Parallel-optics technology, requiring simultaneous data transmission across multiple fibres, necessitates the use of a multifibre connector. Factory-terminated MPO/MTP connectors, available in 12-fibre or 24-fibre arrays, are ideal for this purpose. For instance, a 10G system could utilize a single MPO/MTP (12 Fibre) connector between two switches, with modules on the connector’s end to transition to a 12 Fibre breakout LC duplex or SC duplex cable assembly, facilitating switch connectivity. Configurations for 40G and 100G systems, while similar, require slight adjustments.
MPO/MTP Connectivity: A Symphony of Benefits
MPO/MTP connectivity offers a multitude of advantages, including high-density solutions that save space in data centres, reduced cable load in raised floors, pre-connectorised solutions that eliminate the need for on-site splicing, and reliability assured by factory testing. These connectors are also forward-compatible, supporting emerging high-speed protocols without the need for infrastructure overhauls.
The MTP Advantage: Precision and Performance
While MPO and MTP connectors may appear similar, the MTP connector, a registered trademark and design of US Conec, offers distinct advantages. The MTP connector’s floating internal ferrule and spring design ensure a precise and reliable connection, even under load, and provide maximum clearance for ribbon fibres, preventing damage in high-density applications.
Conclusion: Navigating the MPO/MTP Landscape
When specifying an MPO/MTP system, it’s crucial to consider the correct polarity options and the gender of pins on cables and outlets. The choice between MPO and MTP connectors should be guided by the specific performance and reliability requirements of your application, with the MTP connector often being the preferred option for its enhanced capabilities.
