pluggable cwdm laser diodes datasheet
1. product information
part number：tosa-d5514b222-pm
product description: the pluggable to56 cwdm series laser diodes are 1.27μm~1.61μm multiple quantum well (mqw) structured distributed-feedback(dfb) laser modules. these laser diodes are built in a pluggable to56 package with monitoring pin-pd for fiberoptic communication systems. these modules are ideally suitable for 2.5gbps transmission applications. the products are telcordia gr-468 qualified, and in compliance with rohs requirement.
applications:
█ telecommunication transceivers
█ datacom transceivers
█ fiberoptic sensors
features:
█ cwdm laser diode module
█ signal rate up to 10/25gb/s
█ lc receptacle tosa package
█ high output power（>2mw)
reliability: telcordia gr-468. rohs
2.performance specifications
absolute maximum ratings
stresses in excess of the absolute maximum ratings can cause permanent damage to the device. these are absolute stress ratings only. functional operation of the device is not implied at these or any other conditions in excess of those given in the operational sections of the data sheet. exposure to absolute maximum ratings for extended periods can adversely affect device reliability.
