40G Transceivers Cover QSFP and CFP

Next to the 100G modules, the high data rate 40G modules cover CFP and QSFP transceiver. 40G Ethernet is an important technology in the data center as enterprises transition the aggregation/spine layers of their network towards higher speeds.

The Quad Small Form-factor Pluggable (QSFP) is a compact, hot-pluggable transceiver used for data communications applications. Allowing data rates from 4x10 Gbit/s, used to connecting switches, network, computers and servers. The QSFP specification accommodates Ethernet, Fibre Channel, InfiniBand and SONET/SDH standards with different data rate options. QSFP+ transceivers are designed to carry Serial Attached SCSI, 40G Ethernet, QDR (40G) and FDR (56G) Infiniband, and other communications standards. QSFP modules increase the port-density by 3x-4x compared to SFP+ modules.

The 40GbE QSFP transceiver can also be used with interconnect applications that put together four independent 10-Gbps data lanes in each direction to deliver 40-Gbps aggregate bandwidth. Which offering 3 times the density of traditional SFP ports and supports speeds up to 10Gb/s per channel (suitable for 8G Fiber Channel and 10G Ethernet). The system is ideal for switches, routers, and host bus adapters where bandwidth is essential. Companies can also deploy the transceiver for use in datacom/telecom switch and router connections, in addition to data aggregation and backplane applications.

QSFP copper cable assemblies are a low cost option for short-reach applications. There are both active and passive QSFP cable assemblies to support Fiber Channel, Infiniband, and Ethernet protocols. The backshells include a positive latching system and cables feature a pull-to-release tab.

CFP transceiver supports both 40G and 100G.

Main features of 40GBASE CFP modules include:

-Support for 40GBASE Ethernet and OTU3 standards.
-Interoperability with respective industry IEEE- and/or OTU3-compliant interfaces.
-Variety of interface choices for 40 Gigabit Ethernet and 10 Gigabit Ethernet connectivity.
-Support for "pay-as-you-populate" model.
-Support for digital optical monitoring (DOM).
