Optiva Reference & Timing

Optiva OTS-1 Reference Oscillator Links are optimized for 1, 5, 10 and 100 MHz high-level reference signal input. Each unit comes with a 15 dB adjustable gain range capability to provide ideal level match for signal distribution. The OTS-1 Ref series features low phase noise and high-dynamic-range, with optically-isolated DFB lasers that run cool and have low power consumption requirements.

Optiva OTS-IRIG (Inter-Range Instrumentation Group) B000 / 1 PPS (Pulse Per Second) Fiber Optic Intra-Facility Links provide for simultaneous transmission of IRIG-B000 and 1 PPS, or one signal each over fiber. These high-performance links feature low jitter and sharp rise and fall times.

Optiva Reference Oscillator and IRIG Links are SNMP compliant. They can be housed in the same chassis and monitored by the same Network Management System (NMS) as Optiva HD video, audio, serial data, and USB extension / distribu­tion cards to support transport of multiple signal formats and frequency bands in a single flexible platform.

A consultation with your EMCORE representative, or authorized EMCORE reseller is the 1st step in designing your system. Email Us, or call 626-293-3400, Ext. 3501 for a design consultation.
