Optical IRIG-B / 1 PPS Distribution

IR-140
1PPS / IRIG-B

over Optical Fiber Distribution Unit

KEY FEATURES DATA SHEET

Overview

The IR-140 is a 1PPS/IRIG-B over multi-mode optical fiber distributor unit which can either be used to convert a 1PPS/IRIG-B signal into an optical signal, or an optical signal to multiple IRIG-B / 1PPS outputs. It is available as IR-140-T and IR-140-R.
IR-140-T 1PPS/IRIG-B Transmitter: converts a 1PPS/ IRIG-B Input and transmits over a 850nm multi-mode optical fiber.

Optical IRIG-B / 1 PPS Distribution

IR-140-R 1PPS/IRIG-B Receiver: receives an Optical 1PPS/IRIG-B Input over 850nm multi-mode optical fiber and converts the optical input to 4 x 1PPS / IRIG-B BNC outputs.
The IR-140-R may also be used in conjunction with either IR-140-T or IR-316 units to transmit and distribute a 1PPS or IRIG-B signal over 850nm multi-mode optical fiber links.
