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)
