VCL-2728, 1PPS / IRIG-B over Optical Fiber Distribution Solution

Get Data Sheet

VCL-2728 is a comprehensive 1PPS/IRIG-B over multi-mode optical fiber distribution solution which comprises of two units - VCL-2728-T and VCL-2728-R.

VCL-2728-T, 1PPS/IRIG-B - Transmitter: converts a “1PPS/ IRIG-B Input” and transmits over a 850nm multi-mode optical fiber.

VCL-2728-R, 1PPS/IRIG-B - Receiver: receives a “Optical 1PPS/IRIG-B Input” over 850nm multi-mode optical fiber and converts the optical input to 4 x 1PPS / 4 x IRIG-B BNC outputs.

The VCL-2728-R may also be used in conjunction with either VCL-2728-T; VCL-2486-G or with VCL-2486-I units to transmit and distribute a 1PPS/IRIG-B signal over 850nm multi-mode optical fiber links.

Features and Highlights:

Nanosecond accuracy output referenced to the optical 1PPS / IRIG-B Input (DCLS)
Transparent to Optical 1PPS / IRIG-B Input (DCLS)
Supports Unmodulated IRIG-B (DCLS)
Output shall be phase-synchronized to the input
Up to 4 x 1PPS / IRIG-B Outputs (DCLS)
