The SPB-9780RW-1510G series is high performance module for 10GBASE LX-4, Serial ATA/ATA2, SONET OC-48 / SDH STM-16, Gigabit Ethernet 1000BASE-LX and 1x/2x Fibre Channel single fiber communications by using 1510 nm transmitter and 1590 nm receiver. It is with the SFP 20-pin connector to allow hot plug capability. Digital diagnostic functions are available via an I2C. The transmitter section uses a multiple quantum well 1510 nm DFB laser and is a class 1 laser compliant according to International Safety Standard IEC 60825. The receiver section is designed to receive 1590 nm signal. The receiver section uses an integrated 1590 nm detector preamplifier (IDP) mounted in an optical header and a limiting post-amplifier IC.
