Product Description
The MRV SFP-GDCWXD-39 is a specialized SFP transceiver designed for long-distance optical networking, capable of transmitting data at 1.25 Gbps over single-mode fiber (SMF) for up to 50 kilometers. Unlike more common transceivers operating at 1310nm or 1550nm, this module uses a wavelength of 1390nm. This specific wavelength suggests its potential use in Coarse Wavelength Division Multiplexing (CWDM) systems, where different wavelengths are combined to increase fiber capacity, or for specific applications requiring this particular spectral window. It adheres to the standard SFP form factor, allowing for hot-swapping and easy integration into a wide array of network equipment such as switches, routers, and media converters. The transceiver is equipped with a duplex LC connector, providing a secure and reliable connection point for the fiber optic cable. The 50km reach capability makes it suitable for backbone networks, metropolitan area networks (MANs), and extending connectivity between geographically separated enterprise locations. MRV Communications, a provider of optical networking solutions, engineered this transceiver for robust performance and reliability. The use of a less common wavelength like 1390nm might be driven by specific network designs, interference avoidance, or compatibility with other optical components in a CWDM deployment. This makes the SFP-GDCWXD-39 a niche but valuable component for advanced fiber optic network architectures.
