Terahertz LTX-5515T-850 - 2 Gigabit Analog Fiber Link Transmitter, 850nm, MM/ST

The LTX-5515 enables the precise conveyance of one analog channel plus four digital channels of information over fiber optic links ranging from meters to more than 10 kilometers.

The LTX-5515 enables the precise conveyance of one analog channel plus four digital channels of information over fiber optic links ranging from meters to more than 10 kilometers. Incoming analog data is digitized to 12-bit precision at 100 mega-samples per second and transmitted over optical fiber at one giga-bit per second. The receiver acquires this digital data and accurately reconstructs the analog signal at the far end of the fiber optic link.

The analog signal bandwidth is from DC to 25 MHz ( -3 dB ). Two input voltage ranges are provided, ± 1 Volt and ± 5 Volts. The input impedance of the transmitter analog channel may be set to 50 ohms or 1 megohm (75 ohms is optional). Multiplexed along with the analog data, are four independent TTL/CMOS/LVTTL digital signals that may be toggled at rates of up to 48 Mb/s.

Two models are available. Selection depends on the fiber type and the length of the fiber optic link that is required. The LTX-5515-850 transmits at 850 nm over multi-mode fiber optic links of up to 250 meters in length, while the LTX-5515-1310 transmits at 1310 nm over single-mode fiber to span distances exceeding 10 km.

Applications include data acquisition for plasma physics experiments, signal transmission and control of equipment at high voltage potentials, transmission of high quality video, and precise noise-free signal transmission in hostile EMI environments.
