The IEEE 802.3z standard includes 1000base-SX for transmission over multi-mode fiber, 1000base-LX for transmission over single-mode fiber, 100base-FX is a version of Fast Ethernet over optical fiber. It uses a 1300 nm near-infrared (NIR) light wavelength transmitted via two strands of optical fiber, one for receive(RX) and the other for transmit(TX), 100base-SX is a version of Fast Ethernet over optical fiber. It uses two strands of multi-mode optical fiber for receive and transmit. ZKTel produces complete range for FE and GE optical fiber transceivers..table{ border-collapse:collapse;}.table
