Key Features

21 m cable length
50/125 µm OM4 multimode fiber
8-fiber MPO-to-MPO female connectivity
APC-polished MPO interfaces
Type B polarity
Connect 8-fiber MPO interfaces with female MPO connectors at both ends.

Provide a 21 m multimode optical path between equipment or structured-cabling endpoints with this 8-fiber MPO-to-MPO patch cable. The cable uses 50/125 µm OM4 multimode fiber and terminates in female MPO connectors at both ends. APC-polished MPO interfaces and the stated 8-fiber construction make its connector and fiber configuration clear when matching existing MPO infrastructure. Type B polarity is specified for installations that require this polarity arrangement through the MPO connection. That detail matters when the cable must match the polarity method already used by connected equipment, cassettes or trunk pathways. Female MPO connectors at both ends support connections where the mating interface is intended for a female MPO cable end. N390B-21M-8AP is the 21 m member defined by OM4 multimode fiber, 8 fibers, APC polish and Type B polarity. Select it for optical runs where cable reach, fiber count, connector gender and MPO polarity must be specified together. Its MPO-to-MPO construction suits point-to-point fiber paths between compatible optical endpoints without changing connector format along the run.

Ideal For

Data-center cross-connects requiring a 21 m 8-fiber OM4 MPO path.
Equipment-to-equipment multimode fiber runs using female MPO interfaces.
Structured cabling pathways that require Type B MPO polarity.

Frequently Asked Questions

What is included with N390B-21M-8AP?▾

N390B-21M-8AP specifies a 21 m multimode fiber patch cable with 50/125 µm OM4 fiber, 8-fiber MPO construction, female MPO connectors at both ends, APC polish and Type B polarity. These details identify the cable configuration for matching compatible MPO endpoints.

What connectors are on this fiber cable?▾

The cable has MPO female connectors on both ends, forming an MPO-to-MPO female connection. Both connector ends are specified with APC polish. Match the connector gender and APC interface requirement to the mating MPO connections in the intended optical path.

What does Type B polarity mean for this cable?▾

Type B is the polarity arrangement specified for this MPO cable. Polarity must match the method used throughout the connected MPO path, including the connected equipment and any intervening structured-cabling components, so that the installed connection follows the required fiber mapping.

What fiber type does the cable use?▾

This cable uses OM4 multimode fiber with a 50/125 µm core and cladding specification. It contains 8 fibers and has a 21 m length, making those three values central checks when matching it to an existing multimode MPO fiber pathway.
