SFP transceiver module BlueOptics SFP-1GEZXLC-120-BO 1250 Mbit/s 1550 nm

The BlueOptics SFP-1GEZXLC-120-BO is an SFP fiber-optic transceiver module for single-mode links, supporting a data rate of 1250 Mbit/s over distances up to 120 km. It operates at a wavelength of 1550 nm, uses an LC duplex optical interface and is housed in a metal casing. The module requires a 3.3 V supply and has a compact, lightweight design intended for use in switches, routers and other networking equipment that accept SFP form-factor transceivers.

Advantages

This SFP transceiver provides long-reach single-mode connectivity with a standardized SFP interface and LC duplex connector for bidirectional optical transmission. The metal housing offers mechanical robustness and thermal stability, while the low 3.3 V operating voltage and lightweight construction simplify integration into existing networking platforms. The module is built to MSA-compliant dimensions and supports optical communications protocols up to 1.25 Gbit/s.

Suitable for

• Long-distance single-mode fiber links (up to 120 km)
• Gigabit Ethernet and compatible 1.25 Gbit/s optical applications
• Installation in SFP-compatible switches, routers and storage systems
• Point-to-point backbone and metropolitan area network connections

Key specifications

• Maximum data transfer rate: 1250 Mbit/s (1.25 Gbit/s)
• Wavelength: 1550 nm
• Maximum link distance: up to 120 km over single-mode fiber
• Optical connector: LC duplex
• Operating voltage: 3.3 V
• Material and finish: metal housing, silver color
• Weight: 0.003 kg

How to use

Insert the module into a compatible SFP slot on the target device according to the device manufacturer’s instructions. Use single-mode fiber patch cords with LC duplex connectors to connect the transceiver to the remote transceiver or patch panel, observing correct TX/RX orientation. Ensure connected hardware supports 1.25 Gbit/s optical modules and, if required, enable Digital Diagnostic Monitoring (DDM/DOM) in the host device to monitor real-time parameters such as supply voltage, temperature and optical power.

Recommendations

Use single-mode fiber rated for long-distance transmission and high-quality LC patch cords to achieve the specified 120 km reach. Verify compatibility with the host device firmware and confirm support for DDM/DOM if monitoring is needed. Avoid excessive mechanical stress on the fiber and protect transceiver ports from dust when not connected.
