ATM Multimode Fiber Transceivers for SONET OC-3/SDH STM-1 in Low Cost 1x9 Package Style Data Sheet Features • Full Compliance with ATM Forum UNI SONET OC-3 Multimode Fiber Physical Layer Specification • Multisourced 1 x 9 Package Style with Choice of Duplex SC or Duplex ST* Receptacle • Wave Solder and Aqueous Wash Process Compatibility • Manufactured in an ISO 9002 Certified Facility Applications • Multimode Fiber ATM Backbone Links • Multimode Fiber ATM Wiring Closet to Desktop Links • ATM 155 Mbps/194 MBd Encoded Links (available upon special request) Description The HFBR-5200 family of transceivers from Agilent 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. HFBR-5204/-5204P/-5204T 1300 nm 500 m HFBR-5205/-5205A/ -5205AT/-5205P/-5205T/ -5205PE 1300 nm 2 km 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 HFBR-5205/-5205T 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 3.0. 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 HFBR-5100 family of FDDI Transceivers which are specified for use in this 4B/5B encoded physical layer per the FDDI PMD standard. *ST is a registered trademark of AT&T Lightguide Cable Connectors. ATM 500 m Backbone and Desktop Links The HFBR-5204/-5204T are 1300 nm products which are similar to the HFBR-5205/5205T except that they are intended to provide a lower cost SONET OC-3 link to distances up to 500 meters in 62.5/125 µm multimode fiber optic cables. Transmitter Sections The transmitter sections of the HFBR-5204 and HFBR-5205 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. 3 ELECTRICAL SUBASSEMBLY DUPLEX ST RECEPTACLE DIFFERENTIAL DATA OUT PIN PHOTODIODE SINGLE-ENDED SIGNAL DETECT OUT QUANTIZER IC PREAMP IC OPTICAL SUBASSEMBLIES DIFFERENTIAL LED DATA IN DRIVER IC TOP VIEW Figure 1a.
