Product Description
The 3Com SFP-GE-LX-SM1490-BIDI is an advanced Gigabit Ethernet SFP transceiver module that utilizes Bi-Directional (BiDi) technology. This innovative feature allows the module to transmit and receive data over a single strand of single-mode fiber optic cable, significantly reducing the amount of cabling required and optimizing fiber utilization. It achieves this by employing different wavelengths for transmission and reception: 1490nm for transmitting and 1310nm for receiving. Designed for 1000Base-LX applications, this module supports Gigabit Ethernet speeds and is intended for use with single-mode fiber. It offers a maximum transmission distance of up to 10 kilometers (approximately 6.2 miles), making it suitable for medium to long-reach network connections within campus environments or between nearby buildings. The use of a single LC simplex connector is characteristic of BiDi transceivers, as it accommodates the single fiber strand. This BiDi SFP module is ideal for network upgrades or deployments where fiber infrastructure is limited or costly to expand. By halving the number of fiber strands needed for a point-to-point link, it provides a cost-effective solution for extending Gigabit Ethernet connectivity. It is compatible with network devices featuring SFP ports that support this specific BiDi configuration, ensuring flexibility in network design and implementation.
