AFCT-5179xZ SC Duplex Single Mode Transceiver Data Sheet Description Features The AFCT-5179xZ transceiver is a high performance, cost SC duplex single mode transceiver effective module for serial optical data communications Single +3.3 V or +5 V power supply applications specified for a signal rate of 125 MBd. It is Multisourced 1 x 9 pin configuration designed for Fast Ethernet applications and is also com- patible with EFM baseline 100BASE-LX10 standard over Manufactured in an ISO9001 certified factory dual single mode fiber. Aqueous washable plastic package This module is designed for single mode fiber and Interchangeable with LED multisourced 1 x 9 trans- operates at a nominal wavelength of 1300 nm. It incor- ceivers porates Avago Technologies high performance, reliable, Unconditionally eye safe laser IEC 825/CDRH Class 1 long wavelength optical devices and proven circuit tech- compliant nology to give long life and consistent service. Designed for EFM (Ethernet in the First Mile) baseline The transmitter section uses a Multiple Quantum Well 100Base-LX10 performance over dual single mode laser with full IEC 825 and CDRH Class I eye safety. fiber The receiver section uses a planar PIN photodetector for RoHS compliant low dark current and excellent responsivity.
