## Long description

The Black Box LFP421 fiber optic SFP network transceiver module is engineered for high-speed fiber optic data transmission in modern networking environments. Featuring a standard SFP interface, this module delivers a maximum data transfer rate of 1250 Mbit/s and operates at a 1310 nm wavelength. Housed in a durable metallic enclosure, it provides a reliable solution for enterprise networks, telecommunication infrastructures, and connecting switches or routers over fiber optic cabling.
Advantages
This network transceiver module supports high-speed data throughput up to 1250 Mbps, making it perfectly suited for demanding applications such as Gigabit Ethernet. The hot-pluggable interface design allows administrators to install or replace modules on the fly without interrupting overall network operations when requirements change. Built with a robust metallic enclosure, the unit offers enhanced physical durability and operational reliability. Furthermore, its design is compatible with standard SFP slots found on a wide range of networking hardware, providing a flexible option for fiber infrastructure expansion.
Suitable for
Connecting network switches and routers over single fiber infrastructure
Enterprise networking upgrades requiring Gigabit Ethernet speeds
Telecommunication applications utilizing a 1310 nm wavelength
Environments requiring hot-pluggable optical modules for flexible maintenance
When it may not be suitable
This transceiver module may not be suitable for multi-mode fiber cabling setups, as it is specifically designed for single-mode fiber optic systems. Additionally, it is not compatible with network equipment that lacks standard SFP slots or requires non-standard proprietary transceiver interfaces.
Key specifications
Data transfer rate up to 1250 Mbit/s
Operating wavelength of 1310 nm
SFP interface form factor
Durable metallic enclosure
Hot-pluggable design
How to use
To install the transceiver module, ensure that the network device is powered on if hot-swapping is supported, or power down the device according to manufacturer guidelines. Gently slide the module into an available SFP slot on your switch or router until it clicks securely into place. Connect the appropriate single-mode fiber optic cable with a compatible connector to the transceiver port. Verify the link status through the network device management interface to confirm successful data transmission.
What to consider before purchase
Verify compatibility with your existing network switches or routers and their available SFP slots
Confirm that your network cabling infrastructure utilizes single-mode fiber and matches the 1310 nm operating wavelength
Assess your bandwidth requirements to ensure the 1250 Mbit/s data rate meets your application needs
Always handle optical transceiver modules with care, avoiding direct eye exposure to laser light and protecting the optical bores from dust and contamination by using dust caps when not connected to fiber cables.
