AFBR-5205Z ATM Multimode Fiber Transceivers for SONET OC-3/SDH STM-1 in Low Cost 1x9 Package Style

Data Sheet

The AFBR-5200Z family of transceivers from Avago Technologies provide the system designer with products to implement a range of solutions for multimode fiber SONET OC-3 SDH STM-1 physical layers for ATM and other services.

These transceivers are all supplied in the new industry standard 1x9 SIP package style with either a duplex SC or a duplex ST* connector interface.

ATM 2000 m Backbone Links

The AFBR-5205Z/-5205TZ are 1300 nm products with optical performance compliant with the SONET STS-3c OC-3 Physical Layer Interface Specification. This physical layer is defined in the ATM Forum User-Network Interface UNI Specification Version This document references the ANSI T1E1.2 specification for the details of the interface for 2000 meter multimode fiber backbone links.

Selected versions of these transceivers may be used to implement the ATM Forum UNI Physical Layer Interface at the 155 Mbps/194 MBd rate.

The ATM 100 Mbps/125 MBd Physical Layer interface is best implemented with the AFBR-5100Z family of FDDI Transceivers which are specified for use in this 4B/5B encoded physical layer per the FDDI PMD standard.
• Full compliance with ATM Forum UNI SONET OC-3 Multimode Fiber Physical Layer Specification
• Multisourced 1x9 package style with choice of duplex SC or duplex ST* receptacle
• Wave solder and aqueous wash process compatibility
• RoHS Compliance
• Multimode fiber ATM backbone links
• Multimode fiber ATM wiring closet to desktop links
• ATM 155 Mbps/194 MBd encoded links available upon
special request

Transmitter Sections

The transmitter sections of the AFBR-5205Z series utilize 1300 nm InGaAsP LEDs. These LEDs are packaged in the optical subassembly portion of the transmitter section. They are driven by a custom silicon IC which converts differential PECL logic signals, ECL referenced shifted to a +5 Volt supply, into an analog LED drive current.
*ST is a registered trademark of AT&T Lightguide Cable Connectors.

Receiver Sections

The receiver sections of the AFBR-5205Z series utilize InGaAs PIN photodiodes coupled to a custom silicon transimpedance preamplifier IC. These are packaged in the optical subassembly portion of the receiver.

These PIN/preamplifier combinations are coupled to a custom quantizer IC which provides the final pulse shaping for the logic output and the Signal Detect function. The data output is differential. The signal detect output is single-ended. Both data and signal detect outputs are PECL compatible, ECL referenced shifted to a +5 volt power supply.

Package

The overall package concept for the Avago transceivers consists of three basic elements the two optical subassemblies, an electrical subassembly, and the housing as illustrated in the block diagrams in Figure 1 and Figure 1a.

The package outline drawing and pin out are shown in Figures 2, 2a, and The details of this package outline and pin out are compliant with the multisource definition of the 1x9 SIP. The low profile of the Avago transceiver design complies with the maximum height allowed for the duplex SC connector over the entire length of the package.

Figures 2b and 2c show the outline drawings for options that include mezzanine height and extended and flush shields respectively.

The optical subassemblies utilize a high volume assembly process together with low cost lens elements which result in a cost effective building block.

The electrical subassembly consists of a high volume multilayer printed circuit board on which the IC chips and various surface-mounted passive circuit elements are attached.

The package includes internal shields for the electrical and optical subassemblies to insure low EMI emissions and high immunity to external EMI fields.

The outer housing including the duplex SC connector or the duplex ST ports is molded of filled non-conductive plastic to provide mechanical strength and electrical isolation. The solder posts of the Avago design are isolated from the circuit design of the transceiver and do not require connection to a ground plane on the circuit board.

The transceiver is attached to a printed circuit board with the nine signal pins and the two solder posts which exit the bottom of the housing. The two solder posts provide the primary mechanical strength to withstand the loads imposed on the transceiver by mating with the duplex or simplex SC or ST connectored fiber cables.

Note The “T” in the product numbers indicates a transceiver with a duplex ST connector receptacle. Product numbers without a “T” indicate transceivers with a duplex SC connector receptacle.
