4.3 Frequently Asked Questions
What optical parameters are recommended in order for the MobileAccess network to
operate with the highest performance?
1.
Answer.
Three parameters are specified for every installation:
•
Single-mode Fiber: Corning SMF 28 or equivalent
•
Back Reflection: Less than 45 dB of back reflection @1310 nm
•
Loss: Total end to end optical loss should be less than 1.5 dB @1310 nm
What does MobileAccess recommend as the best method to achieve these
parameters for a reliable system?
2.
Answer.
The end to end fiber backbone should include only fusion splicing or APC
polished connectors for all fiber interconnections.
Which optical connector type does MobileAccess recommend for the highest
performance network with long term reliability?
Answer.
We use the SC/APC connector for MobileAccess products and this is the
connector that we would recommend in the building infrastructure as well. We have found
that this connector is the optimal connector from a cost versus performance perspective for
use with our products. It offers a consistently low back reflection and low loss. It is currently
the lowest cost connector in its performance class
3.
In green field turnkey installations, MobileAccess will use only SC/APC connectors in the
network in order to warrant system performance
Are connectors other than SC/APC recommended or allowed as long as they are
APC?
4.
Answer.
Any connector with an APC polish may be used in the fiber link. The APC polish
is available as an option on most fiber optic connectors. There is a list of popular
connectors that are available with an APC polish at the end of this FAQ.
APC is an abbreviation for Angle Polished Connector. The APC polish consistently
provides the lowest back reflection. The high performance analog nature of the
MobileAccess products makes this low back reflection for required for optimum
performance.
It should be noted, however, that the SC/APC connector is the only connector type that
directly connects to the MobileAccess antenna system products.
5.
My installer says that he has a connector with very low back reflection and loss but
it does not have an APC polish. Is this non-APC connector acceptable?
