Electrical connector

An electrical connector comprising:

• a dielectric housing;
• pairs of signal modules held adjacent one another in said housing, each said signal module comprising:
• a mating edge having a row of mating contacts;
• a mounting edge having a row of mounting contacts;
• and
• a plurality of conductors electrically connecting each said mating contact with a respective mounting contact;
• wherein said pairs of signal modules include long lead frame pairs and short lead frame pairs arranged in an alternating sequence, wherein said pairs of signal modules comprise differential pairs, and wherein said long lead frame signal modules and short lead frame signal modules cooperate to separate adjacent differential pairs to reduce crosstalk between said adjacent differential pairs.
