Questions & Answers

Q
How do I choose between Singlemode (SM) and Multimode (MM) fiber?
A
Singlemode fiber is best for long-distance, high-bandwidth applications (such as telecommunications or data center backbone connections), while Multimode fiber is suitable for shorter distances within buildings or campuses, providing cost-effective, high-speed connectivity. Although, singlemode has gained popularity for shorter runs since the technology such as SFPs and switches has improved and the cost of the equipment has decreased in recent years.
Q
What is APC polish?
A
APC (Angled Physical Contact) polish refers to a connector end face that is polished at an 8° angle. This angled tip, combined with a specific end face radius, minimizes back reflection to about -60dB. APC connectors are typically green for easy identification.
Q
What is UPC polish?
A
UPC (Ultra Physical Contact) polish refers to a connector end face that has been polished with an extended process, resulting in a slightly more conical head shape and improved surface quality. This type of polish achieves a higher return loss (about -50dB or higher), meaning less back reflection compared to standard PC (Physical Contact) polish, which has about -40dB return loss.
Q
Are these assemblies customizable?
A
You can choose any connector type, cable length from 10 feet up to 5,000 feet, and strand count based on the fiber type (multimode OM1, OM2, OM3, OM4, OM5 or singlemode). A pulling eye can also be added for easier installation. Contact us for additional customization options.
Q
Can I combine multiple assemblies if I need a longer run?
A
Yes, you can couple multiple pre-terminated fiber assemblies using adapter panels or adapters (aka couplers) and patch panels to extend your fiber run.
