Multimode OM1 OM2 Fiber

If we have a multimode OM1 50/125 µm fiber backbone, is it possible to use multimode OM2 62.5/125 µm fiber patch cables on each end? Or vise versa? From 50 µm fiber backbone to 62.5 µm fiber jumpers, it’s OK on the receiver end, but on the transmitter end, the larger core of 62.5 µm into […]

Fiber Cables – Construction, Indoor Application

Glass fiber is coated with a protective plastic covering called the “primary buffer coating” that protects it from moisture and other damage. More protection is provided by the “cable” which has the fibers and strength members inside an outer protective covering called a “jacket”. Most indoor fiber optic cables are tight buffer design, usually they […]

Optical Fibers

An optical fiber (or optical fibre) is a flexible, transparent fiber made of extruded glass (silica) or plastic, typically surrounded by a transparent cladding material with a lower index of refraction. Light is kept in the core by total internal reflection, which make fiber functions as a waveguide, or “light pipe”, to transmit light between […]

OFNR / OFNP / LSZH Fiber Cable

OFNR(Optical fiber, Nonconductive, Riser)is a type of optical fiber cable. As designated by the National Fire Protection Association (NFPA), this cable contains no electrically conductive components, certified for use in riser applications. The riser rated cable is engineered to prevent the spread of fire from floor to floor in a building. OFNP(Optical Fiber Nonconductive Plenum) cables […]

Loose Tube, Indoor / Outdoor Fiber Cables

Loose Tube Cables are constructed with a central strength member and a small protective plastic tube along the wall of the jacket which creates a funnel for several fibers to run. Loose Tubes prevent strain damage on fibers and can be made to provide specific environmental protection. Outdoor cables are loose tube formatted.   Indoor/Outdoor Fiber […]

Choosing The Right Fiber Cable

Choosing the right fiber optic cable is extremely important for any installation. The purpose of the cable is to protect the fibers during installation and the service lifetime. Several types of cable are available. Your choice will affect the level of fiber protection, ease of installation, splicing or termination, and, most importantly, cost. All cables […]

Plenum, Riser, LSZH Cable

Plenum is a fire-safety rating awarded to cables that have undergone rigid tests as outlined by the NFPA (National Fire Protection Association). Plenum rated cables are fire resistant, produce low smoke when burned, and do not have metal conduits. Plenum cables are named after the areas in buildings which they were designed to be routed, the […]
