OFS has announced the release of a new product addition to its existing dispersion slope compensating module (DSCM) range. The newly introduced DSCM caters to the cable television market.
The need for high quality services has increased among customers, with many latest applications including real-time gaming and high definition TV storming the cable television market.
Since chromatic dispersion (CD) is a major concern in the operation of network architectures, the need for dispersion compensation has gained significant importance in optical communication networks. Though there has been a rise in the types of transmission technologies, CD continues to remain an issue of concern, and OFS’s latest DSCM has been designed to take care of this issue. In case of cable television (CATV) networks that are dependent on Dense Wavelength-Division-Multiplexed Passive Optical Networks (DWDM-PON), the extent of reach to the customer base is severely limited by CD. Moreover, in comparison to distance calculated based on loss budget, the allowable transmission distances from economically cheaper directly modulated lasers are shorter due to the phenomenon of chirp dispersion. Optical dispersion compensation enables the cable television operators to gain maximum advantage from the available optical bandwidth.
OFS deals with designing, manufacturing and supplying specialty photonics, optical connectivity, FTTX, optical fiber cable and optical fiber products. The company’s dispersion slope compensating module (DSCM) range of products offers enhanced optical performance and high flexibility in wavelength. The slope dispersion compensation offered by these DSCM products is smooth, while the polarization dependent loss (PDL) is zero.
OFS’s Product Marketing Manager, Mimi Eggert-Hansen, said that the company’s DSCM CATV module will deliver high quality HD content and video services over extended transmission lengths which will enable CATV networks to improve the viewing experience of their subscribers.
