The MGB family consists of small form factor pluggable (SFP) transceiver modules that are specifically designed for high-performance integrated duplex data link over single-mode optical fiber. These transceiver modules are compliant with the SFP Multisource Agreement (MSA) and hot pluggable. These modules offer an easy way to be installed in SFP MSA-compliant ports at any time without the interruption of the host equipment operation. The MGB family of SFP Mini-GBIC Gigabit Ethernet modules can be installed in PLANET Switch products with SFP mini-GBIC interface. The deployment distance can be extended from 100 meters (TP) to 550 meters (Multi-mode, LC), and up to 120 kilometers (Single-mode, LC).
