Agilent AFCT-5179xZ SC Duplex Single Mode Transceiver Data Sheet Features Description The AFCT-5179xZ transceiver is a high performance, cost effective module for serial optical data communications applications specified for a signal rate of 125 MBd. It is designed for Fast Ethernet applications and is also compatible with EFM baseline 100BASE-LX10 standard over dual single mode fiber. This module is designed for single mode fiber and operates at a nominal wavelength of 1300 nm. It incorporates Agilent’s high performance, reliable, long wavelength optical devices and proven circuit technology to give long life and consistent service. The transmitter section uses a Multiple Quantum Well laser with full IEC 825 and CDRH Class I eye safety. The receiver section uses a planar PIN photodetector for low dark current and excellent responsivity. A pseudo-ECL logic interface simplifies interface to external circuitry. • SC duplex single mode transceiver • Single +3.3V or +5V power supply • Multisourced 1 x 9 pin configuration • Manufactured in an ISO9001 certified factory • Aqueous washable plastic package • Interchangeable with LED multisourced 1 x 9 transceivers • Unconditionally eye safe laser IEC 825/CDRH Class 1 compliant • Designed for EFM (Ethernet in the First Mile) baseline 100BaseLX10 performance over dual single mode fiber • RoHS compliant • Two temperature ranges: 0 °C to +70 °C, AFCT-5179BZ/DZ -40 °C to +85 °C, AFCT-5179AZ/CZ Applications • Fast Ethernet • Ethernet in the First Mile Pin Descriptions: Pin 1 Receiver Signal Ground VEER: Directly connect this pin to the receiver ground plane.

The receiver includes internal circuit components to filter power supply noise. Under some conditions of EMI and power supply noise, external power supply filtering may be necessary. If receiver sensitivity is found to be degraded by power supply noise, the filter network illustrated in Figure 2 may be used to improve performance. The values of the filter components are general recommendations and may be changed to suit a particular system environment. Shielded inductors are recommended. The postamplifier is ac coupled to the preamplifier as illustrated in Figure 1. The coupling capacitor is large enough to pass the EFM test pattern at 125 MBd without significant distortion or performance penalty. Figure 1 also shows a filter network which limits the bandwidth of the preamp output signal. The filter is designed to bandlimit the preamp output noise and thus improve the receiver sensitivity. Terminating the Outputs These components will also reduce the sensitivity of the receiver as the signal bit rate is increased above 155 MBd. The PECL Data outputs of the receiver may be terminated with the standard Theveninequivalent 50 ohm to VCC - 2 V termination. Other standard PECL terminating techniques may be used. The Signal Detect Circuit The Signal Detect circuit works by sensing the peak level of the received signal and comparing this level to a reference. DATA OUT FILTER TRANSIMPEDANCE PREAMPLIFIER The two outputs of the receiver should be terminated with identical load circuits to avoid unnecessarily large ac current in VCC. If the outputs are loaded identically the ac current is largely nulled. The Signal Detect output of the receiver is PECL logic and must be loaded if it is to be used. The Signal Detect circuit is much slower than the data path, so the ac noise generated by an asymmetrical load is negligible. Power consumption may be reduced by using a higher than normal load impedance for the Signal Detect output. Transmission line effects are not generally a problem as the switching rate is slow.

The package of this laser is designed to allow repeatable coupling into single mode fiber. In addition, this package has been designed to be compliant with IEC 825 Class 1 and CDRH Class I eye safety requirements. The optical output is controlled by a custom IC which detects the laser output via the monitor photodiode. This IC provides both dc and ac current drive to the laser to ensure correct modulation, eye diagram and extinction ratio over temperature, supply voltage and life.

These studs are not electrically connected. The transceiver is designed for common production processes. It may be wave soldered and aqueous washed providing the process plug is in place. Each process plug can only be used once during processing, although with subsequent use, it can be used as a dust cover.
