2010-01-26 s0151, rev.01 an oplink company features trpeg1-e2g single mode absolute maximum ratings product description multi-rate gigabit ethernet & fibre channel sfp transceivers with digital diagnostics the trpeg1-e2g sfp series of multi-rate fiber optic transceivers with integrated digital diagnostics monitoring functionality provide a quick and reliable interface for gigabit ethernet and 1.062gbd fibre channel applications. the transceivers are designed to support data rates ranging from 1.25gb/s down to 125mb/s. the diagnostic functions, alarm and warning features as described in the multi-source agreement (msa) document, sff-8472 (rev. 9.4), are provided via an i 2 c serial interface. four options are offered with minimum optical link power budgets of 18db, 22db and 24db to support up to 80km link applications. option ex uses a 1310nm dfb laser and provides a minimum optical link budget of 18db, corresponding to a minimum distance of 40km, assuming fiber loss of 0.35db/km. options yx and zx use 1550nm dfb lasers and provide a minimum optical link budgets of 22db and 24db respectively, which correspond to minimum distances of 70km and 80km, assuming fiber loss of 0.25db/km. all modules satisfy class i laser safety requirements in accordance with the u.s. fda/cdrh and international iec-60825 standards. the transceivers connect to standard 20-pad sfp connectors for hot plug capability. this allows the system designer to make configuration changes or maintenance by simply plugging in different types of transceivers without removing the power supply from the host system. the transceivers have colored bail-type latches, which offer an easy and convenient way to release the modules. the latch is compliant with the sfp msa. the transmitter and receiver data interfaces are ac-coupled internally. lv-ttl transmitter disable control input and loss of signal output interfaces are also provided. the transceivers operate from a single +3.3v power supply over operating case temperature ranges of -5c to +70c or -40c to +85c. the housing is made of metal for emi immunity. ? compliant with ieee 802.3z gigabit ethernet specifications ? compliant with sfp msa ? lead free design & fully rohs compliant ? digital diagnostics through serial interface ? internal calibration for digital diagnostics ? distance options to support up to 80km ? eye safe (class i laser safety) ? duplex lc optical interface ? loss of signal output & tx disable input ? -40c to +85c operating case temperature option ? hot-pluggable ? single +3.3v power supply parameter symbol minimum maximum units storage temperature t st - 40 + 85 c operating case temperature 1 commercial t op - 5 + 70 c industrial - 40 + 85 supply voltage v cc 0 + 3.47 v input voltage v in 0 v cc v 1 measured on top side of sfp module at the front center vent hole of the cage. pb
