Optical Break-Out

Cable Assemblies

Molex is a leader in providing innovative break-out

cable assemblies to meet the high density

requirements of the telecommunication and

datacommunication industry. The extensive line of

break-out boxes, break-out tubes and MTP* break-out

assemblies provides customers the flexibility to select

the best transition method to meet their specific

application while optimizing real-estate space savings.

Version 1: Break-out boxes and tubes

Break-out boxes and tubes are the traditional method

that allows a spliceless transition between ribbon fiber

and discrete fibers. The break-out box ensures optical

integrity without the use of bulky splice sleeves.

Version 2: MTP break-out connector

The MTP break-out connector eliminates the use of

break-out boxes or tubes, resulting in valuable card

space savings. The break-out from ribbon fiber to

discrete fiber occurs in the crimp area of the standard

MTP connector, providing additional flexibility when

routing discrete fibers on the line card.

Both versions of break-out assemblies provides up to

80% space savings on the front-panel and can reduce

the system costs by up to 25%. For example, up to 12

Small Form-factor (SFF) transceivers mounted on a

line card can transition to a single MTP connector

mounted on the front panel, versus transitioning to 24

LC connectors or 12 duplex LC connectors.

Molex’s extensive line of spliceless single fiber and

ribbon fiber cable assemblies provides numerous

design options. Break-outs to single-fiber leads

terminated with industry standard LC, MU, FC, SC and

ST connectors are available to connect with the current

installed base of transmitters, receivers and patch

panels. Break-outs to ribbon fiber leads terminated

to MTP, HBMT™ and BMTP™ connectors provide high-

density panel mount and backplane solutions.
