Foxcom's Sat-Light L-Band Fiberoptic Interfacility Links
Sat-Light's L-Band IFLs cover the range of 950 - 2150 MHz (with
optional coverage to 3000 MHz). They are used for the transmission over
single mode fiber optic cable of block downconverted C, extended C, X or
Ku band signals. Transmission of L-Band Inmarsat signals as well as
communication radar transmission and reception are also made possible
using Foxcom's L-Band range of products.
Features
- Broadband Transmission - 950 - 2150 MHz (3000 MHz Available)
- Protocol Transparent - transmits all video, audio and data
modulation formats
- Transmission distances ranging from 100m to 60km
- Gain Control, Indicators, Alarms and Monitors
- Single or Multi Channel up or downlink transmission
- Interface with M & C Systems for remote signal monitoring
The Sat-Light IFLs function as a transparent link between the
satellite antenna and the Network Operations Center (NOC) or control
room. System limitations in using coaxial cable are overcome by the
simplicity and performance of fiberoptic connections to provide the
highest levels in signal quality
Sat-Light IFLs consist of an optical transmitter, which receives the
RF signal from the LNB, and an optical receiver that connects to a
satellite receiver. All satellite modulation schemes are accommodated;
digital or analog. Format independence is achieved by inherently low
phase noise. The RF signal, an entire L-Band polarization, is converted
at the transmitter to an optical signal by direct modulation of a
semiconductor laser diode. At the receive end, the optical signal is
converted back to an RF signal by a photodiode.
Sat-Light 7320/7410F
The 7320 and 7410F Systems transmit and receive an entire L-Band
polarization over singlemode fiber from a satellite antenna to reception
equipment up to 2 kilometers away while preserving signal quality. The
7320 comes with MGC on both the Tx and Rx, providing maximum link
stability. The 7410F has Automatic Gain Control on the Tx, and MGC on
the Rx.
Sat-Light 7000
The 7000 Advanced Interfacility Link transmits and receives an entire
L-Band RF signal over singlemode fiber from a satellite antenna LNB to a
control room up to 10 kilometers away guaranteeing superior signal
quality. This feature rich link includes auto or manual gain control and
front panel RF test ports.
Sat-Light 7225
The 7225 Long Distance Multi- Channel system is a high dynamic range
fiberoptic link. The 7225 transmits and receives an entire L-Band
polarization up to 40 kilometers, providing excellent signal quality
under varying conditions encountered in multi-channel environments. For
ultra-long distance applications the 7225 can be ordered with a 1550 nm
laser, the 7225-15.
Sat-Light 7225H
The 7225H is a multicarrier link designed for high input power
levels. Featuring a high dynamic range laser , the link is ideal for
both up and down link applications. The 7225H provides the same enhanced
performance as the 7225, but allows higher input levels which match the
power output of today's L-Band modems.

PRICES </font></b></font><font face="verdana, Arial, Helvetica, sans-serif"><br>
<br>
<font size="2">There are places on our web site and in our print ads,
where the spaces for prices are intentionally left blank. In other instances,
the <i>advertised</i> price is higher than the price you actually pay
when you order that item. The reason for this is MAP, or Minimum Advertised
Price. </font></font></p>
<p><font face="verdana, Arial, Helvetica, sans-serif" size="2">MAP is a voluntarily
agreement a retailer enters into with a supplier. According to the agreement,
which varies in details from vendor to vendor, the retailer can sell an
item for any price they wish, but may not <i>advertise</i> the item for
an amount less than the Minimum Advertised Price. These agreements help
level the playing field for both the small retailer and the giant retail
chain. Retailers agree to MAP contracts because the vendor makes it worthwhile
for them to do so. A retailer who abides by the agreement can count on
getting first news and early shipments of new products, and generally
enjoys a "favored" status. </font>
<p><font face="verdana, Arial, Helvetica, sans-serif" size="2">At Satcom Resources, while we abide
by our MAP agreements, we want to make it as easy as possible for you,
our customer. Where there is a lower selling price and we can, we will
volunteer it -- no need for a nod-and-a-wink or a secret password. At
Satcom Resources, our lowest selling price is <i>always</i> what you pay. Some Online
Retailers make it difficult to tell you about lower-than-MAP prices. At
Satcom Resources, we've set up workarounds. Either we ask you to call, or we will e-mail
the price.If you still have any questions about MAP policies, feel free
