GBIC provides flexibility in network design with reach capability up to 10 km. Hot-swappable GBIC unit enables change/replacement without the need to power down the line card.The 1000BaseSX (GBIC-SX), 1000BaseLX (GBIC-LX), and Long-Haul (GBIC-LH) GBICs have one optical interface in the form of an SC-type duplex receptacle that supports IEEE 802.3z interfaces compliant with the 1000BaseX standard. Depending on the GBIC you plan to use, it contains either a Class 1 laser of 850 nm for 1000BaseSX (short-wavelength) applications, a Class1 laser of 1300 nm for 1000BaseLX (long-wavelength) applications, or a Class 1 laser of 1300 nm for Long-Haul (long-wavelength) applications.
