IQOTR32
3G/HD/SD-SDI Flexible Fiber Optic Interfacing Module
The IQOTR32 is a user-configurable fiber optic transceiver for bidirectional conversion of 3 Gb/s, HD and SD-SDI signals to 1310 nm optical signals. Ideal for mixed coax and fiber workflows, the IQOTR32 allows the user to configure the inputs and outputs to match their infrastructure needs.

FEATURES
- Single-mode fiber optic receiver and transmitter for 3G/HD/SD-SDI signals
- Independent input selection for each channel, or all outputs follow input mode
- User-selectable 3G/HD/SD-SDI outputs for fiber or coax inputs in accordance with SMPTE ST 424, SMPTE ST 292 and SMPTE ST 259
- Input wavelength range 1260-1620 nm, output wavelength of 1310 nm
- 2x GPI/O control interface
- GPIO embedding for long distance transport within the SDI stream to SMPTE ST 291 user application area specification
