The SPB-7860G series is small form factor pluggable module for Gigabit Ethernet 1000BASE-BX and Fibre Channel single fiber communications by using 1310 nm transmitter and 1490 nm receiver. It is with the SFP 20-pin connector to allow hot plug capability. The transmitter section uses a multiple quantum well 1310 nm DFB laser and is a class 1 laser compliant according to International Safety Standard IEC 60825. The receiver section uses an integrated 1490 nm detector preamplifier (IDP) mounted in an optical header and a limiting post-amplifier IC.
