Will Your Cabling System Meet Today’s Standards?
AMP NETCONNECT Web Seminar Questions & Answers
Could you expand on how singlemode
optical cabling will be used within LAN
structured cable systems?
Singlemode is a significant media for campus backbone applications
as well as selected inside building backbone applications.
Singlemode should be considered for distances over 300 meters.
Will 62.5/125 fiber eventually be a thing
of the past?
This is a little bit of a crystal ball issue but based on the direction of
850nm VCSELs my bet is yes. But it will take a while.
When using centralized fiber cabling,
how do you avoid closets for voice
cross-connects between horizontal and
Centralized cabling does not eliminate the need for closets and the
need for voice cross-connect remains. However because voice does
not require electronics and with centralized data not requiring
electronics in the closet, the powering, HVAC, lighting and total
space requirement is greatly reduced.
Where are the gig standards going? I.e.
62.5 or 50. Do you think 50 will become
1 Gbps Ethernet recognizes both 50 micron (550 meters) and 62.5
micron (300 meters). For 10 Gbps the proposed long wavelength
supports both 50 and 62.5 micron for 300 meters. However for short-
wavelength VCSELs 50 micron has a definite advantage.
What factor of 50/125 fiber has made the
standards committee acknowledged its
The use of short wavelength VCSELs operating at 850 nm means
the need for higher bandwidth at 850nm. Combined with the fact that
VCSELs only emit a spot size of 25 microns the issue of numerical
aperture becomes mute.
Would the faceplates change with the
We have designed our MT-RJ connector to fit in the same faceplates
used by our 110Connect copper jacks.
Are there different fiber requirements for
ATM and GIG e
Not really because they both use the same technology from a
transceiver standpoint. You may see differences because
