The ability to scale, customize and upgrade existing devices has long been a primary value add of the Cisco product line. That legacy continues with Cisco's industry standard SFP fiber optic input/output devices. These devices can not only be added after the initial purchase, but can deployed in a "mix-use" environment of single-mode/multi-mode SFP's and a variety of Cisco GBIC's providing a flexible and customizable solution to meet the demands of today's growing, changing IT infrastructures.

These hot swappable, GLC-SX-MM's provide gigabit up-link capabilities in many Cisco switches, routers and firewalls. These SFP's, or Small Form-factor Pluggable, devices offer support for 50/125, 62.5/125 and laser optimized 50/125 (OM3) fiber providing the ability to connect, or uplink, switches and other Cisco devices. This flexibility allows users to use exsisting cable runs in distances up to 550 m on 50/125, 220M on 62.5/125 and 1km over 50/125 OM3 fiber cables. With full duplex, gigabit transmission these Cisco SFP's are an ideal solution for connecting high speed devices not only in the same cabinet, but devices on different floors and all across the installation.
