QSFP+ 40G LR4 TRANSCEIVERS

LR4 Transmission up to 10km

Long range 40G over singlemode (9/125) fibre

QSFP+ 40G LR4 transceivers are capable of long range 40Gbp/s Ethernet over a pair of singlemode (9/125) fibres. These hot-pluggable modules are often used for connections in data centres, enterprise networks, and telecommunication deployments.

40GBASE-LR4 transmission

QSFP+ LR4 transceiver modules use an LC duplex connector and cabling to transmit 4 x 10Gbp/s channels at four separate wavelengths for an aggregate of 40Gbp/s. The electrical input data is multiplexed to into LAN WDM optical signals over the four wavelengths, which are then de-multiplexed from an optical signal into four individual 10Gbp/s channels.

QSFP+ 40G transceivers only use two fibres, meaning they can only connect to another 40G port with an LR4 transceiver.

When cabled in accordance to recognised cabling standards, QSFP+ 40G LR4 transceivers are capable of transmitting up to 10km over OS1 or OS2 singlemode (9/125) fibre.

Vendor/OEM compatibility

QSFP28 LR4 transceivers can be programmed for compatibility with most major switch and server brands, such as Arista, Cisco, HP, Dell and Juniper (see full list of options above). Complete Connect transceiver modules have a 5-year warranty and a 90-day guarantee to test transceiver compatibility.

If you are looking for alternative long range transmission over singlemode, multimode compatible modules, see other transceivers in our range of QSFP+ 40G transceivers.

EEPROM compatibility code

Having the correct compatibility coding programmed on to your third party optical transceiver will ensure that networking equipment that it is being used in will recognise the optic as an authorised and reputable product. Failure to ensure the correct code is loaded can result in continual non-approved hardware alarms being raised via the console or syslog messages or the optic not being authorised to work with the equipment.

All our optical transceivers are programmed and tested with a special compatibility code that is known as a vendor compatibility EEPROM (Electrically Erasable Programmable Read-Only Memory).
