Testing Transmission delay yellow brick (+light path) (+cam)

● L2 (fiber path - HDSDI frame)

● 16 video channels per fiber (+ 64 analog audio

channels)

● Works between A & B with a circuit* in the GARR

optic fibers infrastructure

● SDI video formats up to 3Gbit (1080p60)

● Auto black if no video present (used as a fault

proof)

● Bottle neck in low-budget use (known from LOLA

experience): cameras (100ms delay)

● ...but most of all…

Transmitted signal

received signal

8* with a proper ROADM (Reconfigurable Optical Add-Drop Multiplex) setup

in Huawei Optix 8800 - Huawei Optix 6800

Transmitted signal

received signal

Back to back (2 ± 1) ms

300km (3 ± 2) ms

It workedwith NO operation - unattended

Future

● Rethinking theatres in terms of a network of locations interconnected (we are GARR and we think networked)

● 3D video (virtual presence) in short term roadmap● Other disciplines (with SDI ultra high fps cameras)
