40GBASE-SR4 QSFP+ transceiver

The Finisar FTL410QD3C is a hot-pluggable QSFP+ optical transceiver built for 40 Gigabit Ethernet and 10x Fibre Channel links. It uses a four-channel full-duplex design with an 850 nm VCSEL array and a single 1x12 MPO receptacle. The module suits data-centre interconnects and high-performance computing clusters that need dense, short-reach connectivity.

Sustained-load behaviour

The unretimed XLPPI electrical interface passes traffic without adding latency from retiming circuits, keeping signal integrity stable across the 1.06 Gb/s to 10.5 Gb/s per channel range. Real-time digital diagnostics monitor Tx and Rx power continuously, so operators can track link health during prolonged high-throughput operation. The commercial case temperature rating of 0 °C to 70 °C supports continuous duty in standard rack environments.

Multimode fibre distance limits

Maximum reach is 300 m on OM3 multimode fibre and 400 m on OM4 multimode fibre at the rated 41.2 Gb/s aggregate rate. Beyond these distances the optical budget is exceeded and error-free operation is not guaranteed. The module does not support single-mode fibre or longer-reach standards such as LR4 or ER4, so buyers needing campus or metro spans must choose a different transceiver type.

Questions about this item

How much heat does the FTL410QD3C generate when running continuously at 41.2 Gb/s?

The module operates within a commercial case temperature range of 0 °C to 70 °C and uses VCSEL array technology with real-time digital diagnostics for Tx and Rx power monitoring.

What patch cables and fiber type are required for the MPO receptacle on this transceiver?

A single 1x12 MPO (MTP12) cable with OM3 multimode fiber supports 300 m links, while OM4 multimode fiber extends reach to 400 m at 10.5 Gb/s per channel.

Will this QSFP+ module work in a legacy switch port that only supports 10 GbE SFP+?

The FTL410QD3C is a 40GBASE-SR4 QSFP+ device with an XLPPI electrical interface; it requires a QSFP+ port and is not compatible with SFP+ slots.
