MTP conversion harness

An MTP® conversion harness is a pre-terminated multi-fiber cable assembly that converts one MTP® fiber-count architecture to another. The Fibernet harness connects 12-fiber MTP® interfaces on one side to 8-fiber MTP® interfaces on the other, enabling data center operators to bridge Base-12 backbone cabling with Base-8 parallel-optics connectivity.

It helps use an installed 12-fiber MTP® backbone with equipment or optical interfaces that use 8-fiber connectivity. In common 2×MTP12-to-3×MTP8 and 4×MTP12-to-6×MTP8 configurations, the harness maps 24 or 48 backbone fibers into 8-fiber interfaces, supporting efficient use of the existing fiber plant.

Yes. The product architecture shown in the Fibernet datasheet places conversion harnesses between 8-fiber transceiver interfaces and existing 12-fiber MTP® trunk cabling through STAR MTP® modules. This allows the trunk layer to remain in service while the end connectivity is adapted.

The published ordering table includes 1×MTP12 to 2×MTP8, 2×MTP12 to 3×MTP8, and 4×MTP12 to 6×MTP8 configurations. Connector gender, cable length, fan-out length, polarity and loss class are selected as part of the FCH ordering code.

The harness is available in direct or crossed polarity and is designed for deployment using polarity management Method A. The ordering structure lists Standard Cross, Low Loss Cross, Standard Direct and Low Loss Direct options.

The datasheet references bend-insensitive OM3, OM4 and OM5 multimode fiber as well as OS2 single-mode fiber. The published FCH ordering example explicitly shows OM3 and OM4 options; for OM5 or OS2 ordering codes, confirm the required configuration with Fibernet.

For the published MM MT Low Loss specification, connection insertion loss is 0.1 dB typical and 0.3 dB maximum. The datasheet also specifies 0.6 dB maximum total end-to-end loss for assemblies up to 5 meters and return loss greater than 20 dB.

MPO is the standardized multi-fiber push-on connector format. MTP® is US Conec’s high-performance MPO connector implementation and is compliant with MPO interface standards. This page uses MTP® because the Fibernet product is specified with MTP® Elite connectors.

Typical applications include data centers, high-density fiber environments, storage area networks (SANs), communications rooms and data communication networks. It is especially relevant when a Base-12 structured cabling backbone must interface with 8-fiber parallel-optics ports.

The Fibernet datasheet lists IEEE 802.3ba for 40 Gb/s and 100 Gb/s and IEEE 802.3bs for 400 Gb/s among the referenced standards. Actual link suitability depends on the selected fiber type, transceiver interface, polarity, connector configuration and optical link budget.
