VCL-2728
Optical to 1PPS / IRIG-B Distribution Solution
Introduction
VCL-2728, Optical to 1PPS (Pulse Per Second) / IRIG-B Distribution Solution is a compact and cost-effective solution to convert “Optical 1PPS / IRIG-B Input” to 4 x 1PPS / 4 x IRIG- B Outputs (BNC). The VCL-2728 must be used in conjunction with either VCL-2486-G or with VCL-2486-I to distribute IRIG- B or 1 PPS signals over 850nm Multi-Mode Optical Fiber links.
