Bookham announced a fully Telcordia qualified tunable small form factor transponder (TSFF). The TSFF has passed more than 2,000 hours of testing - proving its reliability and performance in a footprint 58% smaller than previous generation tunable LFF (large form factor) transponder products. The 2.2" x 3" footprint enables network equipment manufacturers to increase port density, placing two SFF transponders on a card where only one LFF would fit. A variable optical attenuator (VOA) can be integrated into the co-planar receiver package within the transponder, extending the operating dynamic range of the Rx chain to powers greater than 8dBm, and easing network design constraints. An extended band transmitter with 100 50GHz spaced ITU channels is also available, enabled by the Bookham DSDBR tunable laser chip.
