Sharing the same core size as OM2, OM3, and OM4, OM5 fiber distinguishes itself with a lime green jacket. It is meticulously designed and specified to accommodate a minimum of four WDM channels, each operating at a speed of at least 28Gbps per channel, across the 850-953 nm window.

Connector Polish Type

APC Fiber Connector


APC, which stands for Angled Physical Contact, involves polishing the ferrule endface at an 8° angle to reduce back reflection. This angled endface ensures that reflected light leaks into the cladding rather than remaining in the fiber core. It's important to use APC connectors only with other angled-polished connectors to avoid significant insertion loss. APC connectors typically exhibit an optical return loss of -60dB or higher, outperforming other connector types in this regard.

UPC Fiber Connector


UPC stands for Ultra Physical Contact, representing an enhancement of the PC fiber connector achieved through extended polishing for a superior surface finish. The return loss of UPC connectors surpasses that of PC structures, typically reaching nearly -50dB or higher. While UPC connectors offer lower back reflection compared to PC connectors, they are less robust. It's important to be aware that frequent connections and disconnections can lead to surface degradation and subsequent performance decline.

Jacket Types



PVC cables are widely used due to their affordability and accessibility for cable jackets. PVC is soft and resistant to oxidation, making it less prone to burning. However, it has the lowest fire rating among the four main types of cables. One significant concern with PVC is the byproducts generated when it burns. Burning PVC produces black smoke, hydrochloric acid, and various toxic gases, making it undesirable in fire situations.



LSZH, which stands for Low Smoke Zero Halogen, lives up to its name by offering superior fire resistance. This jacket material produces minimal smoke and contains no halogens when burned. It is sturdier than PVC and possesses enhanced flame-retardant properties. Furthermore, LSZH is non-toxic when burned, making it a preferred choice for poorly ventilated environments such as airplanes or subway cars. Despite its advantages, LSZH tends to be more expensive than other jacket materials.



OFNR stands for Optical Fiber Nonconductive Riser, typically associated with PVC jackets. Cables carrying this rating are commonly employed for vertical runs between buildings, although their applications are somewhat restricted. Unlike other ratings, OFNR lacks smoke ratings, rendering it unsuitable for use in ventilation areas irrespective of the ventilation design. However, outside of ventilation areas, OFNR cables remain a popular choice due to their cost-saving design for riser cables.



OFNP, which stands for Optical Fiber Nonconductive Plenum, represents the highest-rated cable jacket, contrasting with PVC. In situations where regulations mandate the use of OFNP, no alternatives are permitted. Consequently, OFNP is ideal for vertical runs in data centers. Its robust jacket mitigates the risk of fire spreading along the cable between floors, and it can be safely installed within ventilation systems.
