With the increasing demand for higher bandwidth, in both the broadcast and live event spaces, 12G SDI is a great option to support higher speed UHD formats (4K, 8K etc), with higher bitrates and a greater number of colours. German network fiber specialists, BroaMan have been early subscribers to this evolution, ensuring their devices are capable of delivering uncompressed, unencrypted video signals, securely and robustly.

“The advantages are obvious,” suggested BroaMan’s Marci Sós. “With eight times the bandwidth of standard HD-SDI, 12G-SDI allows the transmission of high frame rate and deep colour 4K/UltraHD signals, supporting rates up to 100/120fps over a single cable.”

Consequently, BroaMan has been able to announce three 12G SDI capable models in its product portfolio: Mux22-12G / Repeat48-12G / Repeat48WDM-12G.

Mux22-12G converter/multiplexer boasts channel capacity of up to 8x 12G, and 16x 3G/HD/SD-SDI. Features include: Intelligent MicroMux I/O module; Dual Input with adaptive EQ; Dual Output; Optional reclocker for each input or output. MUX22 has optionally the feature to have video path redundancy.

Selectable audio/sync modules include: Intercom module – 4 four-wire ports for Clear-Com (IC422) or RTS (IC485) or generic intercom (IC444) with 4 Line In, 4 Line Out, 4 GPI and 4 GPO; MADI module – 4 duplex SC MADI ports; FrameSync8 module – 8x Word Clock, BNC 1Vpp, BNC 3Vpp, Black Burst (bi-level) or Tri-Level, PAL/SECAM, NTSC, 720p59.94, 720p50, 1080i29.97, 1080i25 with Line, Frame, Pixel, Percent and Degree shift option.

The device also features: Built-In CWDM module; 2 fiber auxiliary ports for third party devices and protocols; Full integration into SANE and Optocore network; Optocore module with 2 LAN ports and 2 SANE/LAN ports; RS485 or optional GPIO port; Word Clock and Tri/Bi-Level sync input and output and Redundant power supplies. It is fully controllable via the Optocore Control Software.

Likewise, the Repeat48-12G / Repeat48WDM-12G interfaces are also 12G/3G/HD/SD-SDI Video/MADI Repeater capable.

Repeat48-12G features include up to 24 video channels/MADI streams; Up to 24 EOE converters, which can be configured as: MADI/SD/HD/12-G/3G-SDI input to fiber transmitter; Fiber receiver to SD/HD/12G/3G-SDI output. The Repeat48 is a set of optical-to-copper (and back) 1RU converters. Functioning as stand-alones, they convert from BNC to fiber (and back) as required.

Repeat48 CWDM features include: Up to 24 video SD/HD/12G/3G-SDI I/O channels/MADI streams; Built-in CWDM or DWDM modules; Auxiliary fiber ports for external MUX/DEMUX connection, enabling Optocore integration.

This converts from BNC to fiber, gathers all of the converted fiber signals and ‘muxes’ them onto a single fiber for easier transportation. For this reason, the R48W is generally bought in pairs or with another WDM capable device, such as a Mux22.

Common features to both are: No configuration or user operation is required (the device is plug & play); In addition, they feature channel status LEDs; Modular hardware design, and Built-in dual power supply with automatic switchover.

Marci Sós summarised,“As market leaders in fiber distribution, BroaMan’s pledge is to always keep ahead of the technological curve, supporting new standards in the evolving world of broadcast signal transmission to ensure the best outcome for our customers, up to their demands.”
