This 40-gigabit QSFP+ transceiver carries 40GBASE-SR4 (IEEE 802.3ba) over parallel multimode fibre. It has a single MPO port and transmits at 850 nm, and it is the short-reach optic in the HPE BladeSystem c-Class 40Gb QSFP+ range.
Reach depends on the glass: up to 100 m on OM3 and up to 150 m on OM4. Fibre patch cords for this module need UPC polish, because angled APC termination is not recommended.
The module runs from a 3.3 V supply and draws 1.5 W at most. It measures 5.19 in deep by 0.72 in wide by 0.54 in high (13.18 x 1.835 x 1.371 cm) and weighs 0.08 lb (35 g). Operating temperature is 0 to 70 C at 0% to 85% non-condensing humidity, and storage temperature runs from -40 to 85 C.
Inside a BladeSystem enclosure it is a supported QSFP+ option for the Virtual Connect FlexFabric-20/40 F8 module, where it serves the module's 40Gb uplink ports. The 300 m SR4 transceiver in the same QSFP+ family reaches farther on the same fibre grades, while the 4x10G breakout SR4 variant is restricted to that same module.
HPE's spare number for this transceiver is 746960-001.
