In general, 10Gb SFP (Small Form-Factor Pluggable) modules are designed to operate at the specified data rate of 10 gigabits per second (Gbps). However, many 10Gb SFP modules are backward compatible and can operate at lower data rates, including 1 gigabit per second (Gbps).If a 10Gb SFP module supports 1Gb operation, it is often referred to as a "1/10Gb" or "1/10" module. This

40GBase CSR4 and 40GBase SR4 are both standards for 40 Gigabit Ethernet over fiber optic cables, but they have some differences.40GBase CSR4 (short for 40 Gigabit Ethernet Consortium Specification Revision 4) uses a special type of multi-mode fiber optic cable called OM3 or OM4, and it uses four lanes of 10Gbps signals over the fiber. It has a maximum reach of 300 meters.40GBase SR4 (short for 40

The QSFP28 (Quad Small Form-Factor Pluggable 28) module has a mechanical form factor with specific dimensions. The dimensions are standardized by industry specifications to ensure compatibility and interoperability between different vendors' products. The main mechanical dimensions of a QSFP28 module are as follows: 100G QSFP28 LR1/ER1Overall Dimensions:Width: 18.35 mm (0.722 inches)Heigh

As of my last knowledge update in January 2022, the Cisco SFP-10G-SR-S is a 10 Gigabit Ethernet short-range transceiver module designed for use with multimode fiber optic cables. The "SR" in its name stands for "short range." The typical operating range for SFP-10G-SR-S is around 300 meters (m) over OM3 multimode fiber and 400m over OM4 multimode fiber.Keep in mind that specifi

OM4 (Optical Multimode 4) is a type of multimode optical fiber commonly used for high-speed data transmission in data centers, local area networks (LANs), and other short-reach applications. OM4 fiber is designed to support higher bandwidths compared to its predecessor, OM3 fiber.The OM4 fiber is optimized for use with vertical-cavity surface-emitting lasers (VCSELs) at a wavelength of 850 nm, whi
