How to Install Fiber Optic Connectors?

As we know, fiber optic patch cord is capped at both ends with fiber optic connectors to allow it to be rapidly and conveniently connected to telecommunication equipment. Fiber optic connector is one of those high quality ceramic components used to achieve accurate and precise connections of the fiber ends. It is a simple device which allows fiber links to be readily connected and disconnected.

How to install fiber optic connectors to optical fibers so that they can achieve accurate and precise connections? The method for attaching fiber optic connectors to optical fibers varies based on connector types. Installation ways of fiber optic connectors largely depends on the connector types. Generally, connectors can be categorized into no-epoxy/no-polish connectors and epoxy-and-polish connectors. The following text elaborates on how to install these two kinds of connectors respectively.

No-epoxy/no-polish Connector Installation

How to install no-epoxy/no-polish (NENP) connectors to optical fibers? A no-epoxy/no-polish connector includes an precisely polished endface. When installing an NENP connector, there is no need to use an epoxy or to polish the endface. The field fiber is mechanically spliced to a factory-cleaved fiber stub. The following picture is an illustration of no-epoxy/no-polish connector.


The installation process begins with preparing the field fiber, which is done by stripping the protective coating down to the bare glass. Once the fiber is cleaned, it is then cleaved with a precision cleaver. Next step is to insert the field fiber into the connector until it is seated against the factory-stubbed fiber and locked into place mechanically by a rotating cam or other means. Typically this step is achieved by using a tool that holds the connector and activates the mechanical splice by a button or lever.

Epoxy-and-polish Connector Installation

How to install epoxy-and-polish (EP) connectors to optical fibers? The most common types of EP connectors use heat- or anaerobic-curing techniques. A heat-cure connector uses heat to harden an epoxy, which takes several minutes. An anaerobic EP connector uses a two-part epoxy, a hardener that is inserted into the connector and an activator on the fiber.

To install an EP connector, an epoxy must be inserted into the connector ferrule first to form a bond between the field fiber and the connector’s ferrule, and then the endface needs to be hand-polished. Next, the field fiber is stripped down to the bare glass and cleaned. If the connector is heat-cure, the fiber is inserted into the connector and placed in an oven for the epoxy to cure. If the type of connector is anaerobic, the bare fiber is painted with an activator and inserted into the connector. Once the epoxy has been cured, the fiber stub which is protruding above the ferrule is scribed and removed. The final step is to polish the endface of the connector using a fixture and several different polishing films.

Notes for Fiber Optic Connector Installation

Besides different installation methods for different connector types, several things need to be paid attention to when installing fiber optic connectors, especially when a fiber patch cord has two different types of connectors, such as ST-LC fiber patch cable or FC-SC fiber optic patch cord.

  • The bared fiber must be thoroughly cleaned with isopropyl alcohol.Never clean the fiber with a dry tissue.Before the connection is made, the end of each fiber must have a smooth finish that is free of defects such as hackles, lips, and fractures.
  • The cable should be cut about one inch longer than the required finished length.
  • Be sure to use strippers made specifically for use with fiber rather than metal wire strippers because damage can occur and then weaken the fiber.

Any problems with a connector, such as poor installation and uncleanness, can greatly influence the transmission and reception of the light power. And such problems may render the fiber optic system inoperative. So it is very necessary to know something about installation of fiber optic connectors.

Introduction to MTP/MPO Fiber Optic Cable

MTP stands for multi-fiber termination push-on. MTP connector is designed as a high-performance version of the multi-fiber push on (MPO). The two terms both are used for fiber-optic cabling, and they are often used interchangeably. MTP/MPO fiber cable takes its name from the MTP/MPO connector, which allows high-density connections between network equipment in telecommunication rooms. MTP/MPO connectors are paving the way for increased data transmission speeds and rack density. The following text will thoroughly cover types, advantages and applications of MTP/MPO fiber optic cables.

Types of MTP/MPO Fiber Optic Cable

There are different types of MTP/MPO fiber cable based on various criteria. According to the core of the fiber, MTP/MPO fiber cable are categorized into MTP/MPO single mode fiber patch cords and MTP/MPO multi-mode fiber patch cords. According to the connectors on both ends, there are mainly two configurations for MTP/MPO fiber patch cables. One is the MTP/MPO connector to MTP/MPO connector, which is often called MTP/MPO trunk cable. The other is MTP/MPO connector to standard LC/FC/SC/ST/MTRJ connectors (generally MTP/MPO to LC), which is often called the MTP/MPO harness cable, or MTP/MPO fan-out cable. The following picture shows an MTP/MPO trunk cable and an MTP/MPO harness cable.

Advantages of MTP/MPO Fiber Optic Cable

The MTP/MPO fiber system is a truly innovative group of products which moves fiber optic networks into the new millennium. MTP/MPO connector, as a kind of multi-fiber connector, is most commonly used for 12 or 24 fibers. It has about the same size of a SC connector and provides up to 12 or 24 times the density, thereby offering savings in circuit card and rack space. Using MTP/MPO trunk cables, a complete fiber optic backbone can be installed without any field termination being required. Moreover, MTP/MPO connector are compatible with VZ TPR.9431, IEC-61754-7 and EIA/TIA-604-5. It uses a simple push-pull latching mechanism for easy and intuitive insertion and removal.

MTP/MPO fiber optic cable is also called MTP/MPO fiber jumper. It is one kind of fiber optic patch cord which utilizes precision ferrules, precise housing dimension and metal guide pins to ensure fiber positioning when mating and give excellent performance. And the easy installation of MTP/MPO fiber optic cables saves time and money. They can optimize network performance and maximize lifespan. MTP/MPO multi-fiber jumpers deliver the performance and reliability needed in today’s demanding high-speed broadband and data networks. They are designed to cater for up-scaling needs and future technologies growth.

Applications of MTP/MPO Fiber Optic Cable

MTP/MPO fiber optic cable is the choice for a wide variety of applications. They can be used for backbones, disaster recovery, building fiber optic distribution, quick setup of new wiring hubs, warehouses, direct termination of ribbon cables, repair of plug and play universal system solutions, and parallel optical interconnects between servers. Besides these general applications, MTP/MPO trunk cable and MTP/MPO harness cable, two commonly used MTP/MPO fiber patch cords, have their respective special uses. MTP/MPO trunk cables are available in 12-144 count. These high count MTP/MPO assemblies are ideal for backbone and data center applications that require a high fiber count in a limited space. MTP/MPO fan-out assemblies provide connection to equipment or panels that are terminated with ST, SC, FDDI, or ESCON connectors and meet a variety of fiber cabling requirements. Such assemblies are pre-wired available for patch panels and wall enclosures.

Fiberstore offers single mode and multi-mode MTP/MPO assemblies, such as MTP-LC, MTP-ST, simplex and duplex. UPC MTP/MPO assemblies and APC MTP/MPO cables can also be provided. All fiber counts are available in plenum, riser, or outdoor ratings to suit different kinds of environment.
