Trans data elektronik (tde) has re-developed its tML system for increased network requirements, supporting transceivers to 800GbE. This allows QSFP, QSFP-DD and OSFP transceivers to be used even more efficiently and split into ports with lower data rates (4 x 100GbE or 8 x 100GbE). In turn this enables data centre and network operators to increase the port density of their switch and router chassis and make better use of existing hardware.
The new breakout module will find its use in high-speed data centres and modern telecommunications infrastructures.
“Breakout applications have become firmly established in the high-speed sectors. With our tML breakout modules, customers can now use transceivers up to 800GbE and still split them into smaller, clearly structured port speeds. This allows them to combine maximum port density with very clear, structured cabling,” said André Engel, tde Managing Director.
The current high-speed transceivers in the QSFP, QSFP-DD, and OSFP form factors have MPO connectors with 12, 16, or 24 fibres – in multimode (MM) or single-mode (SM). Typical applications such as SR4, DR4, and FR4 use eight fibres of the 12-fiber MPO, while SR8, DR8, and FR8 use sixteen fibres of a 16 or 24-fiber MPO. This is where tde comes in with its tML breakout modules: depending on the application, the modules split the incoming transmission rate into, for example, four 100GbE or eight 100GbE channels with LC duplex connections. This allows multiple dedicated links with lower data rates to be provided from a single high-speed port – for switches, routers, or storage systems, for example. Alternatively, special versions with other connector faces such as MDC, SN, SC, or E2000 are available.
Tde also relies on front-integrated MPO connectors for the latest generation of tML breakout modules: The MPO connections are plugged in directly from the front via patch cables. Compared to conventional solutions with rear MPO connectors, this greatly simplifies structured patching, ensures clarity in the rack, and facilitates moves, adds, and changes during operation.
A very high port density can be achieved without the need for separate fanout cables. Eight tML breakout modules can be installed in the tML module carrier with one height unit.
