A New Generation of Fibre Optic Connectivity Solutions for the Satellite Communications Industry
15 August 2007
PPM Fiber Optic Ltd is playing a major role in supporting major Satellite Operators implement network development plans to existing teleport sites and earth ground station facilities to accommodate industry consolidation, fulfil global expansion needs and meet service convergence.
RF design engineers at PPM have been working closely with satellite equipment manufactures, network engineer, network installer and systems integrator to realise the next generation, future proof transmission fabric based on a product platform known as Vialite.
Conventional satellite communication inter-facility links that once transported RF payloads over copper cable now transmits economical IF and L-band payloads over single mode optical fibre.
Benefits of PPM’s Vialite Fibre Optic Connectivity Link Solutions are:
- Extensive bandwidth
- Low attenuation making it effectively transparent
- Immunity to EMI and RFI
- Highly reliable and low maintenance
- Install and forget technology
- Future proof connectivity platform
- Flat frequency response
- Flexible and light weight eases installation
PPM's Vialite connectivity solution forms an important part of the overall interconnect operational platform installed by Satcom Operators. This fibre optic platform is protocol transparent and comes in several format options. Plug-in converter modules can be housed in 19" 1U and 3U chassis hardware, or accommodated in 'converter sleeve' for standalone applications. Vialite is a transmission solution that can be viewed as a unity gain black box, and as such what traffic goes into the Vialite link comes out.
The Vialite platform also comes with optional dual redundant, hot swappable power supplies, M&C capability and 1:1 fully redundant up- and down-links realised with the aid of an RF splitter and redundancy switch.
NEW VIALITE RF FIBER OPTIC INTEFACE FOR THE SYSTEMS INTEGRATOR
Most recently, PPM launched its ground breaking OEM RF fibre optic interface module. The OEM module enables Systems Integrator to build an RF fibre interface readily and extremely easily into up/down-links, modems, HPAs, RF distribution, and VSAT equipment.
NEW VIALITE MULTIPLEXING SOLUTION
Through a recent collaboration with a global Satcom Operator, RF engineers at PPM have realised a CWDM (Coarse wavelength division multiplex) platform enabling the Operator to fully utilise existing dark fibre by transporting multi-channels over a single fibre. Up to eight channels can be multiplexed onto one signal mode fibre for long haul payload transportation. Vialite CWDM is an ideal transport solution that supports the emerging, wavelength-assigned, service provision model.
