Switch and router manufacturers implementing QSFP+ ports in their products frequently allow for the use of a single QSFP+ port as four independent 10 Gigabit Ethernet connections, greatly increasing port density. For example, a typical 24-port QSFP+ 1U switch would be able to service 96x10GbE connections. [55] [56] [57] There also exist fanout cables to adapt a single QSFP28 port to four independent 25 Gigabit Ethernet SFP28 ports (QSFP28-to-4×SFP28) [58] as well as cables to adapt a single QSFP56 port to four independent 50 Gigabit Ethernet SFP56 ports (QSFP56-to-4×SFP56). [59] Applications [ edit ] Ethernet switch with two empty SFP slots (lower left) PR originally specified in IEEE 802.3av is a 10 Gigabit Ethernet PHY for passive optical networks and uses 1577nm lasers in the downstream direction and 1270nm lasers in the upstream direction. Its PMD sublayer is specified in Clause 75. Downstream delivers serialized data at a line rate of 10.3125Gbit/s in a point to multi-point configuration. [24]

LX4 is a port type for multi-mode fiber and single-mode fiber. It uses four separate laser sources operating at 3.125Gbit/s and Coarse wavelength-division multiplexing with four unique wavelengths around 1310nm. Its 8b/10b PCS is defined in IEEE 802.3 Clause 48 and its Physical Medium Dependent (PMD) sublayer in Clause 53. [24] SFP transceivers are right-handed: From their perspective, they transmit on the right and receive on the left. When looking into the optical connectors, transmission comes from the left and reception is on the right.
