690T, 690R - Overview 3
3 Overview
The 690T is a high-performance fiber optic transmitter for SD-SDI, HD-SDI and
3G-SDI signals. The unit converts up to two channels of serial digital signals to
light pulses that are transmitted over a dual single mode cable to a 690R receiver
that converts them back to serial digital signals. The 690T and the 690R pair have
a transmission range of 10km (more than 6.2 miles) for 3G-SDI.
The 690T and the 690R feature:
•A maximum data rate of up to 3Gbps, enabling it to be used for standard
definition, high definition and the new 3G high definition serial digital video
signals (3G-SDI)
•Two SDI gold-plated BNC connectors each for the transmitter and the receiver
•SD-SDI, HD-SDI and 3G-SDI support of video pathological patterns for
SMPTE 259M, SMPTE 344M, SMPTE 292M and SMPTE 297-2006
Standard Definition (SD-SDI)means an NTSC or PAL compatible video format,
consisting of 480 (for NTSC) or 576 (for PAL) lines of interlaced video
High Definition (HD-SDI)means a video format, consisting of 720 active lines of
progressive video or 1080 lines of progressive or interlaced video
3G-SDI means a video format, consisting of 1080 lines of progressive video
•Support of data rates of 270Mbps, 1483.5Mbps, 1485Mbps and 2970Mbps
•SMPTE 297-2006 compatible electrical-to-optical interfaces
•HDTV compatibility
•Reclocking and equalization on each channel
•Cable equalization up to 200m for 1.5GHz HD signals, and 100m for 3GHz
HD signals
•Strict regulation in accordance with Class 3R Laser Eye Safety in
compliance with ANSI Z136 and IEC 60825-1:2007
•5V DC power adapters and housing in Kramer Pico TOOLS™ enclosures.
Four units can be rack mounted side−by−side in a 1U rack space with the
optional RK-4PT rack adapter
