AFCT-5805xZ 155 Mb/s Single Mode Fiber Optic Transceiver for ATM, SONET OC-3/SDH STM-1 Data Sheet Description General The AFCT-5805xZ transceiver is a high performance, cost effective module for serial optical data communications applications specified for a data rate of 155 Mb/s. It is designed to provide a SONET/SDH compliant link for intermediate reach links operating at +3.3 V or +5.0 V input voltage. Transmitter Section The transmitter section of the AFCT-5805xZ consists of a 1300 nm InGaAsP laser in an eyesafe optical subassembly (OSA) which mates to the fiber cable. The laser OSA is driven by a custom IC which converts differential input PECL logic signals, ECL referenced (shifted) to +3.3 V or +5 V supply, into an analog laser drive current. Receiver Section The receiver utilizes an InGaAs PIN photodiode mounted together with a transimpedance preamplifier IC in an OSA. This OSA is connected to a circuit providing post- amplification quantization, and optical signal detection.

Block Diagram Receiver Signal Detect Applications Information Signal Detect is a basic fiber failure indicator. This is a single-ended PECL output. As the input optical power is decreased, Signal Detect will switch from high to low (deassert point) somewhere between sensitivity and the no light input level. As the input optical power is increased from very low levels, Signal Detect will switch back from low to high (assert point). The assert level will be at least 0.5 dB higher than the deassert level. Typical BER Performance of Receiver versus Input Optical Power Level Transceiver Specified for Wide Temperature Range Operation The AFCT-5805xZ transceiver can be operated at Bit-Error-Rate conditions other than the required BER = 1 x 10-10 of the ATM Forum 155.52 Mb/s Physical Layer Standard. The typical trade-off of BER versus Relative Input Optical Power is shown in Figure 2. The Relative Input Optical Power in dB is referenced to the actual sensitivity of the device. For BER conditions better than 1 x 10-10, more input signal is needed (+dB). The AFCT-5805xZ is specified for operation over extended temperature range of -40° to +85°C.

Relative Input Optical Power - dBm. Avg. 2 3 Recommended Circuit Schematic currents, forming transmission lines and shielding, Also, it is important to suppress noise from influencing the fiber-optic transceiver performance, especially the receiver circuit. Proper power supply filtering of VCC for this transceiver is accomplished by using the recommended, separate filter circuits shown in Figure 3 for the transmitter and receiver sections. These filter circuits suppress VCC noise over a broad frequency range, this prevents receiver sensitivity degradation due to VCC noise. I t i s recommended that surface-mount components be used. Use tantalum capacitors for the 10 µF capacitors and monolithic, ceramic bypass capacitors for the 0.1 µF capacitors. Also, it is recommended that a surface- mount coil inductor of 3.3 µH be used. Ferrite beads can be used to replace the coil inductors when using quieter VCC supplies, but a coil inductor is recommended over a ferrite bead. All power supply components need to be placed physically next to the VCC pins of the receiver and transmitter. Use a good, uniform ground plane with a minimum number of holes to provide a low-inductance ground current return for the power supply currents. In order to ensure proper functionality of the AFCT-5805xZ a recommended circuit is provided in Figure 3. When designing the circuit interface, there are a few fundamental guidelines to follow. For example, in the Recommended Circuit Schematic figure the differential data lines should be treated as 50 ohm Microstrip or stripline transmission lines. This will help to minimize the parasitic inductance and capacitance effects. Proper termination of the differential data signals will prevent reflections and ringing which would compromise the signal fidelity and generate unwanted electrical noise. Locate termination at the received signal end of the transmission line. The length of these lines should be kept short and of equal length. For the high speed signal lines, differential signals should be used, not single-ended signals, and these differential signals need to be loaded symmetrically to prevent unbalanced currents from flowing which will cause distortion in the signal. Maintain a solid, low inductance ground plane for returning signal currents to the power supply. Multilayer plane printed circuit board is best for distribution of V CC , returning ground NO INTERNAL CONNECTION In addition to these recommendations, Avago Technologies Application Engineering staff is available for consulting on best layout practices with various vendors mux/demux, clock generator and clock recovery circuits.

Recommended Solder Fluxes and Cleaning/Degreasing Chemicals Solder fluxes used with the AFCT-5805xZ fiber-optic transceiver should be water-soluble, organic solder fluxes. Some recommended solder fluxes are Lonco 3355-11 from London Chemical West, Inc. of Burbank, CA, and 100 Flux from Alpha Metals of Jersey City, NJ. Recommended cleaning and degreasing chemicals for the AFCT-5805xZ are alcohol’s (methyl, isopropyl, isobutyl), aliphatics (hexane, heptane) and other chemicals, such as soap solution or naphtha. Do not use partially halogenated hydrocarbons for cleaning/degreasing. Examples of chemicals to avoid are 1.1.1. trichloroethane, ketones (such as MEK), acetone, chloroform, ethyl acetate, methylene dichloride, phenol, methylene chloride or N-methylpyrrolidone. 20.32 (0.800) AFCT-5805xZ Process Plug The AFCT-5805xZ transceiver is supplied with a process plug for protection of the optical ports with the Duplex SC connector receptacle.

See the Regulatory Compliance Table 1 for details. Additional information is available from your Avago Technologies sales representative. Most equipment designs utilizing these high-speed transceivers from Avago Technologies will be required to meet the requirements of FCC in the United States, CENELEC EN55022 (CISPR 22) in Europe and VCCI in Japan. Electrostatic Discharge (ESD) There are two design cases in which immunity to ESD damage is important. The first case is during handling of the transceiver prior to mounting it on the circuit board. It is important to use normal ESD handling precautions for ESD sensitive devices. These precautions include using grounded wrist straps, work benches and floor mats in ESD controlled areas. The second case to consider is static discharges to the exterior of the equipment chassis containing the transceiver parts. To the extent that the duplex SC connector is exposed to the outside of the equipment chassis it may be subject to whatever ESD system level test criteria that the equipment is intended to meet. 6 The AFCT-5805xZ has been characterized without a chassis enclosure to demonstrate the robustness of the part’s integral shielding. Performance of a system containing these transceivers within a well designed chassis is expected to be better than the results of these tests with no chassis enclosure. Immunity Equipment utilizing these AFCT-5805xZ transceivers will be subject to radio-frequency electromagnetic fields in some environments. These transceivers, with their integral shields, have been characterized without the benefit of a normal equipment chassis enclosure and the results are reported below. Performance of a system containing these transceivers within a well designed chassis is expected to be better than the results of these tests without a chassis enclosure. Table 1.
