## Summary description

The BlueOptics ET4201-LX-BO is a fiber optic SFP transceiver module designed for high-speed data transmission. It features an LC connector and is made of durable aluminum, weighing only 20 g. This module is ideal for enhancing network connectivity in various applications.

## Long description

The BlueOptics ET4201-LX-BO SFP LC Aluminium is a single-mode fiber optic transceiver module designed for 1000BASE-LX links. Housed in an aluminium SFP cassette and weighing approximately 20 g, this module provides duplex LC connectivity with 1310 nm transmitter and receiver wavelengths and follows MSA form-factor standards for broad hardware compatibility. It supports gigabit Ethernet and related optical protocols over single-mode fiber for link distances up to 10 km when used with appropriate fiber and patching.
Advantages
The transceiver offers a compact SFP form factor that fits standard switch, router and storage system ports. Constructed with an aluminium housing for mechanical stability and thermal dissipation, the module is manufactured to MSA specifications and tested for compatibility with major hardware platforms. Support for Digital Diagnostics Monitoring (DDM/DOM) provides real-time measurements such as supply voltage, laser bias current, transmitted and received optical power, and temperature to aid maintenance and troubleshooting.
Suitable for
 Gigabit Ethernet uplinks and fiber backbone connections
 Interconnecting switches, routers and storage systems over single-mode fiber
 Data center and enterprise campus links up to 10 km
 Environments requiring electromagnetic immunity and low-latency optical links
Key specifications
 Form factor: SFP (small form-factor pluggable)
 Connector type: LC duplex
 Wavelength: 1310 nm (TX and RX)
 Data rate: up to 1.25 Gbit/s (suitable for 1000BASE-LX)
 Fiber type: single-mode fiber
 Maximum link distance: up to 10 km (typical, depending on fiber and link conditions)
 Housing material: aluminium
 Weight: approx. 0.02 kg
 Digital diagnostics: DDM/DOM (SFF-8472 compliant)
How to use
Install the BlueOptics ET4201-LX-BO by inserting the SFP module into a compatible SFP slot on a switch, router or optical transceiver cage until it seats securely. Connect an LC duplex single-mode patch cable to the module and the corresponding fiber port on the remote device, observing correct TX-to-RX polarity. Ensure the host device supports 1000BASE-LX and, if you intend to use DDM/DOM features, confirm that the chassis firmware or operating system exposes diagnostic readings. After insertion and cabling, verify link negotiation and monitor optical power and diagnostic parameters to confirm stable operation.
Usage recommendations
To achieve optimal performance, use high-quality single-mode fiber and LC patch cords, maintain proper TX/RX polarity, and keep the optical connectors clean. Verify that the connected hardware supports 1000BASE-LX and DDM/DOM if diagnostics are required. For long-term reliability, avoid mechanical stress on the module and cables and operate within the equipment’s specified temperature range.
