QSFP+, quad small form-factor pluggable plus, is a compact, hot-pluggable transceiver used for data communications applications. 40G QSFP+ transceiver is a parallel fiber optical module, using four independent optical transmit and receive channels, offering users high-density 40 Gigabit Ethernet connectivity options for high-performance networks. Fiberstore offers a large amount of 40G compatible QSFP+ transceivers branded by many famous companies, like Cisco, HP, Juniper, and Brocade. In this post, some detailed information about HP 40G compatible QSFP+ transceivers will be given.

HP QSFP+is a Multi-Source Agreement (MSA) standard for high speed application, such as 40GBASE, which provides four channels of data in one pluggable interface. Each channel is capable of transferring data at 10Gbps and supports a total of 40Gbps. HP 40G QSFP+ transceivers enjoy several key features: QSFP+ MSA and SFF-8436 compatible, four independently addressable transmit and receive channels, highly compact and electrically hot-pluggable, digital diagnostic monitoring (DDM) interface for better module management, and simplified heat management with reduction in power consumption.

There are many kinds of HP QSFP+ transceivers to support different applications and transmit over various distances. Here are two commonly used types.

HP 40GBASE-SR4 QSFP+ Transceiver: HP 40GBASE-SR4 QSFP+ ransceiver supports link lengths of 100m and 150m, respectively on OM3 and OM4 multimode fibers 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. Digital optical monitoring (DOM) support is present to allow access to real-time operating parameters, which means, it is capable of performing transceiver monitoring and troubleshooting operations with DOM. The image below shows a HPJG325Bcompatible 40GBASE-SR4 QSFP+ transceiver.

HP 40GBASE-LR4 QSFP+ Transceiver: HP 40GBASE-LR4 QSFP+ transceiver enables high speed 4x10G operations. It is designed for use in 40 Gigabit Ethernet links over single mode fiber (SMF) with duplex LC connectors. It is compliant with the QSFP+ MSA and IEEE 802.3ba, and RoHS-6 compliant with built-in DDM interface. It 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. Fiberstore compatible HP JG661A is intended to support up to 10km on single mode fiber cable at a wavelength of 1310nm. The image below shows a HP JG661A compatible 40GBASE-LR4 QSFP+ transceiver.

HP 40G QSFP+ transceivers are well suited for Infiniband, 40GBASE-SR4, 40GBASE-LR4 applications, suitable for short reaches among switches, routers and data center devices. Combined with right fanout cables, these modules can interface up to four SFP+ transceivers.

HP 40G QSFP+ transceivers features high-density and provide users with 40Gbps connectivity for better network performances. Fiberstore supplies various HP 40G QSFP+ transceivers with assured quality and performance. It is guaranteed to be 100% compatible with the equivalent HP optics module.
