Shenzhen, April 13, 2009, Gigalight today rolled out two SFP transceivers, the MCU DWDM SFP and hot swappable GEPON OLT SFP. The new design of MCU DWDM SFP includes 1.25G and 2.67G data rate. MCU is applied for wavelength control, which is one magnitude better than ITU standard. Cross problem has been solved by particular technology. Module receive sensitivity is impressively improved, and its hardware performances are better than international standard, especially the global leading DDM function, which completely realizes DWDM SFP MSA seven items diagnosis. The newly released GEPON OLT optical transceiver is SFP package, MCU burst control, DDM monitoring, and achieve better sensitivity performance than international standard within extended temperature range (-40~85). Now, Gigalight
