FAQ
What type of connector does the Black Box LFP401 SFP module use?
The LFP401 uses a duplex LC connector, which is a common, small-form-factor interface for fiber optic connections. This connector type provides reliable, low-insertion-loss mating with LC-compatible fiber patch cables, making it suitable for high-density network environments where space is at a premium.
What is the maximum data transfer rate supported by this SFP module?
This module supports a maximum data transfer rate of 155 Mbit/s, operating on Fast Ethernet (100Base-X) technology. It is designed for networks requiring up to 100 Mbps Ethernet speeds over fiber optic cabling, with the 155 Mbps capability accommodating overhead and ensuring stable performance.
What fiber mode and wavelength does the LFP401 support?
The LFP401 supports multimode fiber with an 850 nm wavelength. Multimode fiber is typically used for shorter-distance applications, and the 850 nm wavelength is standard for cost-effective, high-performance optical transmission within buildings or campuses, offering a balance of reach and bandwidth.
How far can this SFP module transmit data over fiber?
It supports a maximum distance of 2 km (1.24 miles) over multimode fiber. This reach makes it suitable for inter-building links, campus backbones, or data center interconnects where distances exceed the limitations of copper cabling but remain within typical enterprise network ranges.
Is the Black Box LFP401 hot-pluggable?
Yes, the LFP401 is hot-pluggable, meaning it can be inserted or removed from a compatible SFP port without powering down the network device. This feature allows for maintenance, upgrades, or replacements with minimal disruption to network operations, enhancing flexibility and reducing downtime.
