MRV SFP27DWLR20-18 2.7Gb/s SMF 120km 1563.05nm SFP Transceiver

Product Description

The MRV SFP27DWLR20-18 is a sophisticated Small Form-Factor Pluggable (SFP) optical transceiver module engineered for demanding long-haul telecommunications and data networking applications. It is specifically designed to operate at a data rate of 2.7 Gb/s, making it suitable for high-capacity transmission links. The module utilizes single-mode fiber (SMF), which is the standard for long-distance communication due to its ability to carry optical signals over extended ranges with minimal loss and dispersion. A key feature of this transceiver is its impressive transmission capability of up to 120 kilometers (approximately 74.5 miles) over single-mode fiber. This extended reach is achieved through advanced optical components and potentially integrated amplification or dispersion compensation techniques, allowing it to bridge significant geographical distances. The operating wavelength of 1563.05 nm falls within the C-band of the optical spectrum, often used in DWDM (Dense Wavelength Division Multiplexing) systems, enabling it to coexist with other wavelengths on the same fiber. The SFP27DWLR20-18 is hot-pluggable, meaning it can be installed or removed from compatible network equipment, such as switches, routers, or multiplexers, without the need to power down the device. This ensures network uptime and simplifies maintenance. Its primary function is to convert electrical signals from the host device into optical signals for transmission and to convert incoming optical signals back into electrical signals. This transceiver is a critical component for building robust, high-bandwidth, long-distance fiber optic networks.
