Optic Transceiver

SFP can be regarded as the upgrade version GBIC, SFP is short for Small Form-factor Pluggables, unlike GBIC with SC fiber optic interfaces is with LC interface and the main body size of SFP is only about half of GBIC, which makes SFP space saving. Signal transmitting rate of these modules range from 100Mbps up to 4Gbps or more, working distance of these SFP transceiver modules can be from 500 meters to 100 kilo meters, working wavelength of different SFP modules are typically 850nm, 1310nm and 1550nm, there are also CWDM type SFP transceivers available.
100Base-FX SFP Transceiver
The MFB SFP transceivers using a long wavelength (1310nm) FP LD enable data transmission up to 2km on a multimode optical fiber and up to 60km on a single mode optical fiber.
1000Base-SX/LX SFP Transceiver
The MGB family SFP Mini-GBIC Gigabit Ethernet module can install into Switch products with SFP Mini-GBIC interface.
The distance can be extended from 100 meters (TP), 550 meters (Multi-mode, LC), up to 120 kilometers (Single-mode, LC).
