MTP Trunk Cables

MTP Trunk Cables (Plenum Rated)

MTP FiberShield Specifications

The 40G MTP Trunk Cables with Plenum-rated insulation are the best choice for strict building codes that specify the use of a special material to prevent fire damage. These 40G and 100G MTP (MPO) Trunk Cables with plenum-rated fiber significantly reduce the amount of combustible material in the jacketing material, which is critical when running MTP (MPO) cables through walls, floors, and ceilings.

OptoSpan's 8, 12, and 24 fiber MTP trunk and patch cables feature the company's unique and exclusive FiberShield design. FiberShield uses three times the amount of PVC jacket and DuPont Kevlar to protect the MTP Trunk cables' delicate optical fibers. As a result, a 4.5mm MTP patch cable that is five times stronger than a standard 3.0mm cable is constructed.

Each plenum 40G MTP (MPO) Cable is equipped with a high-performance MPO variant known as the MTP fiber connector, which was developed by US Conec. When used with fiber optic equipment, MTP patch cables with MTP connectors provide significantly reduced signal loss and are fully compatible with MPO devices. MTP connectors are ideal for 40G and 100G MTP fiber networks due to their high performance and durability, as well as a number of innovative features such as a floating ferrule that ensures a secure connection. For more information, please see our main MTP Cables page.

FiberShield MTP trunk cables are 5 times stronger!

FiberShield MTP Trunk Cable Assemblies: OptoSpan's 8-, 12-, and 24-fiber MTP (MPO) Cables with plenum rating offer exclusive FiberShield technology that is 5x stronger than rivals' MTP Patch Cables, as well as 3x more PVC and DuPont Kevlar. These Plenum MTP Trunk Cables are 4.5mm or 3.0mm thick, which protects them from typical installation damage.

How do you choose the right MTP Trunk Cable for your application?

Many factors influence cable selection, such as network optics type, fiber count, cable polarity, MTP connection type, and fiber media type (single-mode or multimode). Please contact us before placing an order if you are unsure or require assistance!

  • 40G MTP (MPO) cables are composed of eight fiber multimode or single mode cables, depending on the QSFP+ type being used and the rate of data transfer required, which can be 40G, 100G or 400G.
  • 100G MTP (MPO) cables are frequently comprised of eight, twelve, or twenty-four multimode or single mode fibers, depending on the QSFP28, CFP, or CXP type and the MTP connection, and support data transfer rates of up to 400G. While they are most frequently used in 10G, 100G, and inter-patch panel connections.
  • 400G MTP (MPO) cables are frequently made up of 8 fiber or 16 fiber multimode or single mode cables, depending on the QSFP-DD type being used.

MTP Trunk Cable Types:

  • 8 Fiber MTP Trunk Cable Assemblies are used to link QSFP+ transceivers that require four send and four receive lanes. The following applications require multimode 40G MTP cables.
    • 40G MTP Cable:  Connects two 40GBASE-SR4 QSFP+ transceivers over a 40G network.
    • 100G MTP Cable:  Connects two 100GBASE-SR4 QSFP28 transceivers over a 100G network.
    • 400G MTP Cable:  Connects two 400GBASE-SR8 QSFP-DD transceivers over a 400G network.
  • 12 Fiber MTP Trunk Cable Assemblies  are typically utilized for trunk and backbone applications at speeds of 40G, 100G, and 400G. The following applications require single mode 40G and 400G MTP cables.
    • 40G MTP Cable:  Connects two 40GBASE-PSM4 or 40GBASE-PLR4 QSFP+ transceivers at 40Gbps.
    • 400G MTP Cable:  Connects two 400GBASE-DR4 or 400GBASE-PLR4 QSFP-DD transceivers at 400G.
  • 24 Fiber MTP Trunk Cable Assemblies  are employed in high-density trunk and 100G applications.
    • 100G MTP Cable:  Connects two 100GBASE-SR10 CFP or CXP transceivers over a 100G network.

Quality and Engineering Excellence

By utilizing our proprietary manufacturing process developed over 15 years of experience, we are able to produce higher performance products using the same components, hence lowering the cost to our clients. OptoSpan cables are made in a Class 10,000 (ISO14644-1, ISO7) clean room facility, which eliminates the potential of end face contamination.

Rohs Compliant

Quality Management Systems

  • ISO 9001: 2008
  • TL9000 (Ver. 5)

Standards Compliance

  • Telcordia GR-326 Core
  • TIA-604-18: FOCIS 18
  • IEC 61754-7-3:2019

OptoSpan fiber optic cables are RoHS compliant.

MTP Trunk Cable Cleaning and Testing

All fiber end-faces, including MTP Connectors, should be cleaned prior to each installation. Due to the increased surface area of MTP Connectors, cleaning them may be significantly more challenging. While cleaning these larger surface areas, pollutants are much more easily transmitted from one fiber to the next within the same array.

OptoSpan recommends cleaning MTP optical cables with these simple MTP Connector cleaners prior to each insertion.

OptoSpan offers a simple MTP Trunk tester for troubleshooting Plenum MTP Cable connections (fiber breaks or faults) during installation or for identifying problems during normal operation.
