V23836-C18-R363 product specification ? october 2006 ? finisar corporation october 2006 rev. a preliminary data 3 description the finisar single mode atm transceiver complies with the atm forum?s network compatible atm for local network app lications document and ansi?s broadband isdn-customer installation interfaces, p hysical media dependent specification, t1.646-1995, bellcore - sonet oc-3 ir -1 and itu-t g.957 stm-1 s-1.1. supported link lengths reach category within standard min. max. 1) unit sdh stm s-1.1 0 15,000 sonet oc-3 ir-1 0 21,000 meters notes: 1) maximum reach over fiber type sm-g.652 as defined by itu-t g.957 and telcordia gr-253-core standards. longer reach possible depending upon link implementation. atm was developed to facilitate solutions in multimedia applications and real time transmission. the data rate is scalable, and the atm protocol is the basis of the broadband public networks bei ng standardized in the international telecommunications union (itu), the former international tele graph and telephone consultative committee (ccitt). atm can also be used in local private applications. the finisar single mode atm transceiver is a single unit comprised of a transmitter, a receiver, and an sc receptacle. this design frees the customer from many alignment and pc board layout concerns. the module is desi gned for low cost wan applications. it can be used as the network end device interface in workstations, servers, and storage devices, and in a broad range of network devices such as bridges, routers, and intelligent hubs, as well as wide area atm switches. this transceiver operates at 155.520mbit/s fr om a single power supply. the differential data inputs and outputs are dc-coupled and pecl compatible.
V23836-C18-R363 product specification ? october 2006 ? finisar corporation october 2006 rev. a preliminary data 4 functional description this transceiver is designed to transm it serial data via single mode fiber. figure 2 functional diagram the receiver component converts the optical serial data into pecl compatible electrical data (rd+ and rd?). the signal detect (sd, active high) shows wh ether optical data is present 1) . the transmitter converts electrical pecl co mpatible serial data (td+ and td?) into optical serial data. the transmitter contains a laser driver ci rcuit that drives the modulation and bias currentof the laser diode. the currents are controlled by a power control circuit to guarantee constant output power of th e laser over temperature and aging. the power control uses the output of the m onitor pin diode (mechanically built into the laser coupling unit) as a controlling signal, to prevent the laser power from exceeding the operating limits. single fault condition is ensured by means of an integrated automatic shutdown circuit that disables the laser when it detects transmitter failures or when v cc is too high. a reset is only possible by turning the pow er off, and then on again. notes: 1) we recommend to switch off the transmitter supply ( v cc tx) if no transmitter input data is applied
