40G QSFP+ (quad small form-factor pluggable plus) module is a compact, hot-pluggable transceiver used for data communications applications. It is the high-density interface addressing deployment of high-performance computing in data center clouds by using four independent optical transmit and receive channels. Compatible HP QSFP+ transceivers provided by Fiberstore are third-party optical modules certificated to be fully compatible with HP Switch/Router product line. HP compatible QSFP+ transceivers have the same functionality with the original. HP 40GBASE QSFP+ modules in this article are mainly introduced in three different types—40G LR4 QSFP+ transceiver, 40G SR4 QSFP+ transceiver and 40G CSR4 QSFP+ transceiver.
HP 40GBASE-LR4 QSFP+ Transceiver
The 40G LR4 QSFP+ transceiver together with the LC connector can support an optical link length up to 10 kilometers over single-mode fiber. 40G LR4 QSFP+ transceivers offer 4 independent transmit and receive channels. In order to realize the function of transmitting 4-channel signals over single-mode fiber, this transceiver has to introduce MUX/DEMUX to multiplex/de-multiplex optical signals. For example, HP 40GBASE-LR4 QSFP+ transceiver enables high speed 4x10G operations. It is compliant with QSFP+ MSA and IEEE 802.3ba, which primarily enables high-bandwidth 40G optical links with duplex LC connectors and can also be used in a 4x10G module for interoperability with 10GBASE-LR interfaces.

HP 40GBASE-SR4 QSFP+ Transceiver
The 40G SR4 QSFP+ transceiver compatible with the 802.3ba 40GBASE-SR4 standard, provides a 40G optical connection using MPO/MTP fiber ribbon connectors. Unlike the 40G LR4 QSFP+ transceiver, this transceiver are used together with multi-mode fiber, supporting with a link length up to 100 meters on OM3 cable and 150 meters on OM4 cable. HP 40GBASE-SR4 QSFP+ transceiver supports link lengths of 100m and 150m, respectively on OM3 and OM4 multi-mode fiber at a wavelength of 850nm. It primarily enables high-bandwidth 40G optical links over 12-fiber parallel fiber terminated with MPO/MTP multifiber connectors and can also be used in a 4x10G module for interoperability with 10GBASE-SR interfaces. The following picture shows a HP JG325B compatible 40GBASE-SR4 QSFP+ transceiver.

HP 40GBASE-CSR4 QSFP+ Transceiver40GBASE-CSR4 QSFP extends the reach of IEEE 40GBASE-SR4 interface to 300 and 400 meters on laser-optimized OM3 and OM4 multi-mode parallel fiber, respectively. Each 10-gigabit lane of this module is compliant to IEEE 10GBASE-SR specifications. This module can be used for native 40G optical links over 12-fiber parallel cables with MPO/MTP female connectors or in a 4x10G mode with parallel to duplex fiber breakout cables for connectivity to four 10GBASE-SR interfaces. Fiberstore compatible HP 40GBASE-CSR4 QSFP module is optimized to guarantee interoperability over the complete specification range of 10GBASE-SR. Take HP JG709A as an example, it is intended to support up to 300m on multi-mode fiber at a wavelength of 1310nm. The image below shows a HP JG709A compatible 40GBASE-CSR4 QSFP+ transceiver.
