A: They fit into the RJ45 Port on the networking devices. For copper sfp, it's a little bit short.

A: SFP-B TYPE:14x12x17mm/0.55x0.47x0.67in (LxWxH)  Facing side is more like square.
SFP-A TYPE:15x10x12mm/0.59x0.39x0.47in (LxWxH)  Facing side is rectangle.

SFP-B is a little big tight than SFP-A;  SFP-A is suitable and flexible, SFP-B is durable and Tighter.
