Abstract
The 300-pin Multi Source Agreement (MSA) and other MSAs provide basic requirements from a transponder or transceiver used in 10Gb/s optical networks. These MSAs typically address a wide range of applications, including: SONET/SDH, 10GbE and 10GFC for Metro, long-haul (LH) and ultra-long-haul (ULH) networks. Nonetheless, being a basic standard, the 300-pin MSA addresses the minimal required specifications set and does not cover the whole set of requirements and applications that system vendors are interested in. For example, widely tunable and extended reach transponders are not included in the 300-pin MSA. Chromatic dispersion is one of the major reach limiting factors in optical networks. In reconfigurable optical networks, chunks of DWDM channels may travel through different routes and therefore require tunable dispersion compensation. In static ULH optical networks, the number of dispersion compensation fibers (DCFs) dictates the amount of residual chromatic dispersion. This residual chromatic dispersion differs from one DWDM channel to the other. Unless it is compensated at the receiver, it further restricts the link length and reduces the distance between one regenerator to the other. This results in shorter links and more O-E-O blocks, which dramatically increases the cost of the network. This paper discusses a specially designed optical dispersion compensation (ODC) device that is packaged in a standard butterfly package and can fit into a 300-pin MSA transponder. A transponder with the proposed ODC can still satisfy all the basic requirements that are described in the 300-pin MSA while providing improved chromatic dispersion tolerance.
