Bulk fiber optic cables and patch cords are various types available(Ribbon, tight buffered, breakout, distribution,...), just the jacket material of bulk fiber optic cable there is a wide selection.

Plenum Rated Cable
Plenum type is with the highest standard for fire-resistant and it require almost no halogen gas be generated in case it got burned. Complies with NFPA-262 and UL-910. Plenum cables must self extinguish and not reignite. Because plenum cables are routed through air circulation spaces, which contain very few fire barriers, they need to be coated in flame-retardant, low smoke materials. These plastics offer good resistance against possible fire, and in the event that they do begin to burn, they will not emit large quantities of harmful fumes. Plenum cables can be installed in plenums without the use of conduit, meeting specific requirements for flammability and smoke generation.

Riser Rated Cable
Comples with UL-1666. Defined for usage in vertical tray applications such as cable runs between floors through cable risers or in elevator shafts. These spaces cannot be used for environmental air. These cables must self extinguish and must also prvent the flame from traveling up the cable in a vertical burn test. Riser type bulk fiber optic cables are also required to be fire-resistant, but it is not so strict as halogen gas produced if it caught on fire. They are certified for use in riser applications, engineered to prevent the spread of fire from floor to floor in a building.

Low Smoke Zero Halogen (LSZH) Rated Cable
Examples of Halogens include Fluorine, Chlorine, Bromine, and Iodine. LSZH fiber optic jackets are more fire-resistant compared with common PVC jacketed cables, even when they are on fire. When burned, LSZH cable emits low smoke and no halogen substances. This feature is designed to not only protect the environment, but the low smoke is also important to the safety and presence of people and the facilities that could be on fire. These cables will self extinguish but cannot pass UL-910 or UL-1666 for a plenum or riser rating. LSZH cables are used in shipboard applications and computer networking rooms where toxic or acidic smoke and fumes can injure people and/or equipment.

ROHS Rated Cable
RoHS, short form for the Restriction of Hazardous Substances in electrical and electronic equipment. RoHS is made for environmental protection and to protect the health of the products' users. RoHS mentioned six types of hazardous substances: Pb,Cd, Hg, Cr6+, PBDE and PBB.

PVC Cable
PVC means polyvinyl chloride, and it is a common plastic cable insulation or jacket. In a fire, PVC-coated wires can form hydrogen chloride fumes, the chlorine serves to scavenge free radicals and is the source of the material's fire retardance.

After the introduction of cable jacket material above, you may figure out how to choose the type of cable jacke. For fire safety and code compliance concerns, choose Plenum rated cable. If fire safety is not any concern or local code requirement, choose PVC for ease of installation and lower cost. BUY Fiber Optic Ribbon Cable, Riser here.
