Discuss QSFP 40G SR4 to 4 SFP 10G SR Transceiver Module


SFP, know and QSFP fiber optic transceiver fiber and module optic cables give people a multitude of high density and low power 4010Gigabit and Gigabit, 1 Gigabit, and 100 Megabit Ethernet connectivity options over fiber or copper media, since we know.
The instance of 40G QSFP transceiver module will result in us to acquire familiarity with it. In 40G QSFP transceiver module data sheet, we can easily realize that about SFP 40G SR4, Cisco thinks, it could be utilized in a 4 x 10 G mode for interoperability with 10Gbase sr interfaces approximately 100m and 150m for OM3 and OM4? If I connect Nexus 55772UP equipped with "six true QSFP ports" to Nexus 7706 using qsfp to sfp+ active cable on the side of 5572UP, and 4 x Cisco SFP 10G SR on the side of 7706, cables respectively, in another word? Somehow, I do believe that this is simply not impossible, but someone thinks that you have fiber optic cables with 40G interface using one side and 4 x 10G SFP (LC connector) on the opposite side. We are able to breakout the one 40G port into 4 seperate 10g uses and ports a QSFP to 4 LC breakout cables to link more than one of 10G ports towards the 7706.
Actually, Cisco sfp 10g aoc3m  supports link lengths of 100m and 150m, respectively, on laser optimized OM3 and OM4 multimode fibers. It primarily enables high bandwidth 40G optical links over 12 fiber parallel fiber terminated with MPO/MTP multiplier connectors. You can be utilized inside a 4 x 10G mode for interoperability with 10Gbase sr interfaces up yo 150m and 100m for OM3 and OM4? Cables, respectively. The worry free 4 x 10G mode operation is enabled with the optimization in the receive and transmit optical sign of the Cisco QSFP 40G SR4 to stop receiver overload or unnecessary triggering of alarm thresholds about the 10Gbase SR receiver, as well being fully interoperable with all of standard 40Gbase sr4 interfaces. 4 x 10G connectivity is performed utilizing an external 12 fiber parallel to 2 fiber duplex breakout cable, which connects the 40GBASE SR4 module to four 10GBASE SR optical interfaces. Cisco QSFP 40G SR4 is optimized to assure interoperability with any IEEE 40GBASE 10GBASE and SR4 SR (in 4 X10G modes).

The transceiver catches up with parallel optical and electric products together with both receiver and transmitter functions being a distinct module. It was designed to be compliant to IEEE 802.3-2012 for 40GBase SR4 over 100 m of OM3 multimode fiber for a price of 41.25 Gbps. This transceiver module is in an option to use four independent 10GBase-SR, IEEE 802.3 Clause 52 Compatible 10 G transceivers using an MPO-to-LC breakout cable (compliant at 100 m 50 plus μm OM3 fiber). The transceiver is also fully compliant together with the sfp h10gb cu1m  specification SFF-8436 shown on the figure.
To aid an effective increasing array of 40 and 10 Gigabit Ethernet applications, Fiberstore offers many transceiver types, each optimized for any different distance and media reach (XSR4, LR4, PLRL4 and SR4CR4, ZR, SR, LRL, ER, SRL, LR and CR and DWDM). Additionally, Fiber SFP ports also support 3 Gigabit Ethernet SFP transceiver types for single mode fiber, multimode fiber, along with Cat 5 copper cables.
