Data Sheet

General

The HFBR-5208M multimode transceiver and HFCT5208M single-mode transceiver from Avago Technolgies allow the system designer to implement a range of solutions for ATM/SONET STS-12/SDH STM-4 applications.

The overall Avago Technolgies transceiver consists of three sections the transmitter and receiver optical subassemblies, an electrical subassembly and the mezzanine package housing which incorporates a duplex SC connector receptacle.

Transmitter Section

The transmitter section of the HFBR-5208M consists of a 1300 nm LED in an optical subassembly OSA which mates to the multimode fiber cable. The HFCT-5208M incorporates a 1300 nm Fabry Perot FP laser in the optical subassembly. In addition, this package has been designed to be compliant with IEC 825 eye-safety requirements under any single fault condition. The OSA’s are driven by a custom, silicon bipolar IC which converts differential PECL logic signals ECL referenced to a +5 V supply into an analog LED/laser drive current.

Receiver Section

The receiver contains an InGaAs PIN photodiode mounted together with a custom, silicon bipolar transimpedance preamplifier IC in an OSA. This OSA is mated to a custom, silicon bipolar circuit providing post amplification and quantization and optical signal detection.

The custom, silicon bipolar circuit includes a Signal Detect circuit which provides a PECL logic high state output upon detection of a usable input optical signal level. This singleended PECL output is designed to drive a standard PECL input through normal 50 PECL load.

Applications Information

Typical BER Performance of HFBR-5208M Receiver versus Input Optical Power Level

The HFBR/HFCT-5208M transceiver can be operated at Bit-Error-Ratio conditions other than the required BER = 1 x 10-10 of the 622 MBd ATM Forum Mb/s Physical Layer Standard and the ANSI T1.646a. The typical trade-off of BER versus Relative Input Optical Power is shown in Figure The Relative Input Optical Power in dB is referenced to the Input Optical Power parameter value in the Receiver Optical Characteristics table. For better BER condition than 1 x 10-10, more input signal is needed +dB .
