   Pluggable 
interfaces are small, hot-swappable, managed port interface modules that provide 
physical layer (copper or fiber) signaling for data, voice, storage and video 
transport networks.
 
 Pluggables started with GBIC (Gigabit Interface Converter) modules, which 
allowed Gigabit Ethernet devices to provide a generic, modular interface to 
optical transceivers. This capability allowed optical transceivers of various 
distances (10km or 80km for example) to be plugged into a switch-card slot 
without changing the card. In the days before GBIC, Gigabit Ethernet switch 
vendors provided a blade of, say, 8 ports of Gigabit to the customer, with all 
the same type of optical interface (mostly multimode). When a customer needed a 
few ports of single-mode optics, they had only two choices:
 
  Each of 
these options is expensive and wastes resources. The GBIC solution provided a 
mechanism of supplying a simple blade with GBIC slots, and allowing the customer 
to choose the optics for each slot individually.Use a media converter, or 
  Buy a separate card for each type of optical interface 
 Fast forward by a few 
years, and GBIC has been 'upgraded' to SFP (Small 
Form Pluggable). SFP optical interfaces are less than ½ the size of GBIC 
interfaces, and the usage (protocols and applications) has dramatically 
expanded. Today, MRV Communications provides an astonishing variety of optical 
and copper interfaces using GBIC and SFP technology, and a wide array of systems 
to which these interfaces attach.
