Qsfp 40g Sr4 Cable

It delivers dependable 40 gbe connectivity over fiber cable for 40gbase sr4 compliant networks with a maximum distance of up to 150 m 492 ft.

Qsfp 40g sr4 cable.

The cisco qsfp 40g csr4 is optimized to guarantee interoperability over the complete specification range of 10gbase sr. Product description this cisco qsfp 40g sr4 compatible qsfp transceiver provides 40gbase sr throughput up to 150m over multi mode fiber mmf at a wavelength of 850nm using a mpo connector. Qsfp 40g cr4 module is very much different from the above mentioned two 40g modules. It is known as 40g qsfp cable or 40g qsfp direct attach cable.

Qsfp 40g sr4 item weight 1 6 ounces product dimensions 7 2 x 5 9 x 1 9 inches item dimensions lxwxh 7 2 x 5 9 x 1 9 inches processor count 1 voltage 240 volts manufacturer cisco systems 605824 asin b00a4s1j62 is discontinued by manufacturer no date first available february 25 2013. It delivers dependable 40 gbe connectivity over fiber cable for 40gbase sr4 compliant networks with a maximum distance of up to 150 m 492 ft. Cisco qsfp 40g sr4 compatible 40gbase sr4 qsfp optical transceiver module for ethernet and data center mmf 850nm 150m mtp mpo dom the cisco qsfp 40g sr4 compatible qsfp optical transceiver module is designed for use in 40gbase ethernet throughput up to 150m over om4 multimode fiber mmf using a wavelength of 850nm via a mtp mpo connector. As we all know the standard specifies mpo as a connector to the 40gbase sr4 csr4 qsfp transceiver.

As previously mentioned in 2010 ieee 802 3ba approved the 40gbase sr4 physical medium dependent pmd multimode parallel optic solution which uses eight fibers to transmit four duplex channels each at 10 gigabit ethernet. To connect a qsfp to qsfp we usually use a mtp 12 fiber trunk cable. The cisco 40gbase csr modules support link lengths of 300 meters and 400 meters respectively on laser optimized om3 and om4 multimode fibers. Digital optical monitoring dom support is also present to allow access to real time operating parameters.

The qsfp40gsr4es is a dell emc qsfp 40g sr4 compatible fiber transceiver module that has been designed programmed and tested to work with dell emc brand switches and routers. Qsfp 40g csr4 can be used for native 40g optical links over parallel cables with mpo mtp connectors or in a 4 10g mode with parallel to duplex fiber breakout cables for connectivity to four 10gbase sr interfaces. Limited by the property of copper cable qsfp 40g cr4 can only reach a transmission distance of 7 meters. The qsfp 40g csr s is a pluggable optical transceiver with a duplex lc connector interface used for connectivity using multimode fiber mmf.

In the 40gbase sr transmission there are eight fibers associated with the channel four fibers for the tx signal and four fibers for the rx signal.
