The development trend for optical transmission equipment |
|
|
Optical transmission equipment with broadband access and comprehensive
service access has become the cosset in the most recent trend of
development. On the one hand, products based on the PDH technique,
which cost less than nine hundred USD, exhibit supreme inexpensiveness;
on the other, the optical transmission equipment that develops on the
basis of SDH technique, more often than not, is required by customers
to be equipped with Ethernet interface or video frequency interface.
As a typical PDH equipment, OM8E1PCM, produced by Heng Guang
Technologies, Co., Ltd in Tianjin, China has integrated eight E1
channels, one 10/100BASE-T Ethernet channel, one NX64bps, V.35 channel
and PCM30 with 30 channels. However, the exquisite equipment featured
by its 2U height and 19- inch width costs only 1000 odd USD. (For more
information about this equipment, please login www.pcm30.com .)
Sometimes, the designer may consider to realize the functions of VDF,
DDF and ODF on the PCM, so as to provide the most customized and
convenient product to clients. Such equipment is various and multiform
in configuration and modality, which includes the European 7R series
and 19-inch configuration.
At the same time, SDH equipment with E1 channel, 1000M Ethernet
interface and multi-channel 100M Ethernet interface has been more and
more popularized. The broadband interface usually will adopt automatic
and dynamic distribution manner, such as RPR technique.

low-priced optical equipment will be developed to include the |
comprehensive service access system. In addition to
10Base-T,100Base-T,1000Base-T with E1,E2,E3,T1,T2,T3 channels, 10/100
auto-adaptation Ethernet, G.703 V35 interface, V11/V24 interfaces,
video frequency, even the SCADA system is about to be able to
transmitted in one or two optical fibers.

One effective way to annoy foreign spammers is to order lots of stuff
from them, and not pay for it.
Everybody pitch in here.

An effective way to annoy netizens is to follow up to spam while
including its entire contents.

John, you seem to have elided the tongue-in-cheek smiley here.
Why would you want to abase yourself like that? You do know that what
you're supposedly advocating here is nothing more than common thievery?
Thanks,
Rich |

Since this is apparently your only post to this ng (at least in a long
time) I assume your only function in life is to prowl groups and
attempt to enforce netiquette.
Have fun!

Oh, I won't keep the crud they ship; I'll throw it away.
