OP+TDMT+8

8-Channel 1.5 Gb/s HD-SDI (or 4-Channel 3 Gb/s HD-SDI) Input, TDM Fiber Transmitter

With the introduction of the OP+TDMT/R+8 family of fiber products, Harris now offers the highest-density signal transport over fiber in the market. This award-winning line of fiber products is capable of transporting up to four 3 Gb/s, eight HD-SDI or eight SD/ASI signals, or any combination equal to 12 Gb/s of transport signals, over a single optical fiber.

Built to reside in the 6800+™ modular core processing platform, OP+TDMT/R+8 fiber products transport up to eight streams of 1.5 Gb/s HD-SDI signals by us-ing the time division multiplexing (TDM) approach. Multiplexing technologies are implemented across the Harris fiber optic portfolio, allowing for cost-effective and expandable designs.

The OP+TDMT/R+8 products are ideal for applications handling a high volume of signals for medium- and long-haul transport.

Product Details

By utilizing a single wavelength on a wave division multiplexing (WDM) system, the OP+TDMT/R+8 fiber products are capable of transporting multiple 3 Gb/s HD-SDI, 1.5 Gb/s HD-SDI, SD-SDI, DVB-ASI or SDTI signals.

The serial fiber link runs at a 12.44 Gb/s proprietary bit stream. The video interfaces are designed in compliance with SMPTE 2036-1, SMPTE 424M, SMPTE 259M, SMPTE 344M, SMPTE 305M, SMPTE 348M and SMPTE 292M. They are able to transport fully independent video or data streams (i.e., the streams can be asynchronous and can move at dif-ferent data rates). Connection and disconnection of one stream has no impact on the transmission of the other streams.

The OP+TDMT/R+8 fiber product line includes a 12 Gb/s TDM transmitter module and a 12 Gb/s TDM receiver module. The transmitter module consists of an input and pre-processing host module, as well as a TDM transmitter sub-module. The receiver mod-ule consists of a TDM receiver sub-module, as well as a post-processing and output host module. Both the transmitter and receiver modules share the same back module. The transmitter is available in 1310 nm single and 40 C-band DWDM wavelengths. Receivers are available as either standard (PIN) or high-sensitivity (APD).
