AFBR-59E4APZ-HT Multimode Small Form Factor (SFF) Transceiver for Fast Ethernet, with LC Connector Data Sheet Description Features The AFBR-59E4APZ-HT is a new power saving Small Form Multisourced 2 5 package style Factor transceiver that gives the system designer a product to Operates with 62.5/125 m and 50/125 m multimode implement a range of solutions for multimode fiber Fast fiber Ethernet. Single +3.3 V power supply This transceiver is supplied in the industry standard 2 5 DIP Wave solder and aqueous wash process compatibility style with an LC fiber connector interface. Manufactured in an ISO 9001 certified facility Compatible with the optical performance requirements of 100Base-FX version of IEEE 802.3u Transmitter RoHS compliant The transmitter section of the AFBR-59E4APZ-HT transceiver LVPECL Signal Detect Output utilizes a 1310 nm LED. This LED is packaged in the optical Temperature range: 40 C to +95 C subassembly portion of the transmitter section. It is driven by an integrated circuit that converts differential LVPECL logical signals into an analog LED drive current. Application Fast Ethernet Receiver The receiver utilizes an InGaAs PIN photodiode coupled to a trans-impedance pre-amplifier IC. It is packaged in the optical subassembly of the receiver. The PIN/preamplifier combination is connected to a quantizer IC, which provides the final pulse shaping for data output. The data output is differential LVPECL. The Signal Detect output is single-ended. Both Data and Signal Detect outputs are LVPECL compatible.

The low profile of the Avago transceiver design Directly connect this pin to the receiver ground plane. complies with the maximum height allowed for the LC connector over the entire length of the package. Pin 2 Receiver Power Supply V RX CC The optical subassemblies utilize a high-volume assembly Provide +3.3 V DC via the recommended receiver power supply process together with low-cost lens elements, which result in a filter circuit. Locate the power supply filter circuit as close as cost-effective building block. possible to the VCC RX pin. The electrical subassembly consists of a high volume multilayer printed circuit board on which the ICs and various Pin 3 Signal Detect SD surface-mounted passive circuit elements are attached. Normal optical input levels to the receiver result in a logic 1 output. The receiver and transmitter sections include an internal shield for the electrical and optical subassemblies to ensure high Low optical input levels to the receiver result in a logic 0 immunity to external EMI fields. output. The outer housing including the LC ports is molded of filled Pin 4 Receiver Data Out Bar RD- nonconductive plastic to provide mechanical strength. The solder posts of the Avago design are isolated from the internal Signal AC coupled LVPECL. See Figure 2. circuit of the transceiver. Pin 5 Receiver Data Out RD+ The transceiver is attached to a printed circuit board with the ten signal pins and the two solder posts, which exit the bottom Signal AC coupled LVPECL. See Figure 2. of the housing. The two solder posts provide the primary mechanical strength to withstand the loads imposed on the Pin 6 Transmitter Power Supply V TX CC transceiver by mating with the LC connector fiber cables. Provide +3.3 V DC via the recommended transmitter power supply filter circuit. Locate the power supply filter circuit as Figure 1 Pin Out Diagram close as possible to the VCC TX pin.
