With our wide variety of fiber optic cables available we can fulfill your requests for broadcasting, mining, wireless, building-to-building, transportation, oil and gas and more.

You’ll have no more expensive testing equipment to buy either — with every order, we provide professional test results for your customer’s needs. Interferometer test results are available for an additional fee.


Discount Low Voltage has multimode 50/125 OM4 plenum fiber cable in stock for contractors and installers. It is sold by the foot for installations of any size.

Once your order is ready, it should arrive in two to five business days unless you select a rush shipping option at checkout.

We can provide you with just about any pre-terminated fiber cable you may need. Our state of the art facility can terminate multimode 62.5- or 50-micron (OM2, OM3 and OM4) as well as singlemode fiber. Standard connector options include LC, SC and ST. We can also terminate other connector types such as MTRJ, FC and APC type. Visit our Pre-Terminated Fiber Assembly page to see these and other options.


A pre-terminated 12-strand OM4 fiber optic cable assembly is perfect for those who have less skill in terminating their own cables or want to reduce time spent on the job site. By ordering from Discount Low Voltage, you receive our low prices and benefit from years of cabling experience and customer relations.


See below for several DLV blog entries with free advice on using and installing these cables. Our AFL fiber optic cable spec sheet and pre-terminated fiber demonstration video are good overviews and include information relevant to any installer.

How to Order: 

For a single pre-terminated fiber, select the length desired from the dropdown field, and click "Add to Cart". Once the pre-terminated fiber is in the Shopping Cart, you may change the fiber to any length required (10-2000+ ft.). If you need multiple pre-terminated cable assemblies, follow the above instructions, then return to the item page and repeat. Multiple lengths of the same cable will be combined in the shopping cart. Please let us know what lengths you need in the "Comments" box during checkout. 

Pulling Through Innerduct/Conduit Questions:

Q: What size innerduct/conduit will these pre-terminated fiber cables fit through? 

A: Most pre-terminated fiber cables we make fit through 1-inch innerduct or conduit. The recommended innerduct size depends on many factors though, including; fiber type, quantity of connectors, length of pull, how many turns during the pull, etc. We recommend installing 1.25-inch or 1.5-inch innerduct/conduit if the option is available. 

Q: Will the pre-terminated fiber fit through 0.75-inch innerduct/conduit? 

A: Maybe. We have had customers successfully pull a pre-terminated fiber though 0.75-inch innerduct/conduit, but we do not recommend this unless you have no other option. Please specify when ordering if you require a pre-terminated fiber that will fit through 0.75-inch and we will do our best to accommodate. You may still need to modify the pulling loop before installation.
