MDM6100 Broadcast Satellite Modem
The Newtec MDM6100 was built upon extensive latest generation RF and flexible programmable technology. Migrating standard distribution links towards the new DVB-S2X standard is as simple as integrating this modem in the head-end while keeping the installed base of IRDs.
A scalable, pay-as-you-grow, licensing and software upgrade mechanism facilitates the launch of new services, or last minute network design changes, without rebuilding the entire network infrastructure. Migration from ASI to GbE and IF to L-band is facilitated by simple in-field installation of license keys.
The brand new DVB-CID carrier identifier is already available as a software option on the MDM6100 and DSNG profiles, as defined by WBU-ISOG, can be easily selected. These profiles define the basic parameters for the most common use cases including the new DVB-S2X standard.
Efficiency at the core
The Newtec MDM6100 Broadcast Satellite Modem is the next generation DVB compliant modem specifically designed for
broadcast applications. The modem supports the DVB-S2 and DVB-S2X, next to the legacy DVB-S and DVB-DSNG standards, as well as Newtec S2 Extensions in order to achieve barrier-breaking efficiency. The unit can act as a single Transport Stream modulator, demodulator or modem.
As a modulator, it is best suited for Broadcast Direct-To-Home, Primary Distribution to Head-Ends and Contribution of elevision
and Radio Content. As a modem or demodulator, it is typically installed in head-ends or at both sides of a contribution link.
The MDM6100 can be used in conjunction with set-top boxes, professional IRD’s or professional satellite demodulators.
Uptime and reliability are essential in the design of the modem, which plays a vital role in the satellite network. Input source
redundancy and the shortest redundancy switch-over times of modems, operating both in 1+1 and N+1 topologies, are setting
the standard in our industry. Advanced capabilities are built in, such as an MPEG Transport Stream analyser, support of SMPTE 2022 FEC at the GbE inputs (for distributed IP headends), and native support of Carrier ID, according to the new DVB standard, as well as in the transport stream NIT Table. Special care was taken to cope with jittery transport stream over IP inputs. Two input ASI and two output ASI ports can be used as monitoring or operational (redundant) interfaces.
Best RF Performance
The Broadcast Satellite Modem performs among the best, offering unmatched bandwidth efficiency optimization options, thereby lowering overall Total Cost of Ownership. The fully automated operation of Newtec´s field-proven Equalink® 3 predistortion technology with its seamless calibration is now available for any satellite transmission application providing up to 10% bandwidth gains in single carrier per transponder constellations.
Clean Channel Technology®, in combination with DVB-S2X or Newtec S2 Extensions, improves satellite efficiency by up to 15%, thereby enabling much smaller carrier spacing. Maximum symbol rates up to 72 MBaud and modulations up to
256APSK (DVB-S2X standard) combined with VCM (Variable Coding and Modulation) allow for maximum throughput in large contribution links.
