Review CISCO 100gbase Lr4 Qsfp Transceiver Lc Over Smf

The Cisco 026521438207 QSFP-100G-LR4-S is a high-performance 100GBASE LR4 QSFP transceiver designed for long-haul applications. This transceiver utilizes a Single Mode Fiber (SMF) with a connector type of LC and supports a reach of up to 10 kilometers.

The 100GBASE LR4 standard, also known as 100G LR4, is a long-wavelength, single-mode fiber optics technology that delivers 100 Gbps (gigabits per second) of data transfer rate over a distance of up to 10 kilometers. The LR4 designation refers to its reach capability, making it an ideal choice for metro and regional networks, data centers, and other applications where high-speed, long-haul connectivity is necessary.

The QSFP form factor, or Quad Small Form-factor Pluggable Plus, is a compact, hot-pluggable, high-density interconnect standard for optical transceivers. The "S" in the part number indicates that this transceiver features a shielded version of the QSFP connector, which helps protect against electromagnetic interference (EMI) and radio frequency interference (RFI) for improved signal integrity.
