SFP transceiver module BlueOptics SFP-GZX-LCI-70E 1250 Mbit/s 1550 nm

The BlueOptics SFP-GZX-LCI-70E is a compact fiber optic SFP transceiver module designed for single-port optical links. It supports a maximum data transfer rate of 1250 Mbit/s and transmits at a wavelength of 1550 nm. The module is lightweight (20 g) and finished in silver, supplied as a single packaged unit to protect the device during storage and transport. It is intended for use in networking equipment that accepts standard SFP modules.

Advantages

The module provides a standardized SFP interface for easy insertion into compatible switches, routers or media converters, enabling optical connectivity without specialized tools. Its 1550 nm operating wavelength is suitable for longer-reach single-mode fiber links, and the 1250 Mbit/s data rate aligns with common Gigabit-capable optical applications. The compact form factor and low weight simplify handling and installation in dense networking environments.

Suitable for

• Single-mode fiber links requiring 1550 nm transmission
• Point-to-point optical connections between switches or routers
• Media converters and access devices with SFP ports
• Environments where a lightweight, hot-pluggable SFP module is needed

Key specifications

• Interface type: SFP form factor
• Maximum data transfer rate: 1250 Mbit/s
• Operating wavelength: 1550 nm
• Physical weight: 0.02 kg (20 g)
• Color/finish: Silver

How to use

Ensure the host device supports SFP transceivers and that fiber cabling matches single-mode specifications for 1550 nm operation. With the device powered according to the host’s instructions, align the SFP module with the SFP slot and insert it until it clicks into place. Connect the appropriate single-mode fiber patch cord to the transceiver’s optical port, observing correct connector type and polarity. The module supports hot-swapping but follow your network equipment’s guidelines for link negotiation and firmware compatibility.

Recommendations

Handle the transceiver by its housing; avoid touching the optical connector face. Use dust caps when the module is not connected and store the unit in its original packaging to prevent contamination. Verify compatibility with the host device and confirm fiber type and connector matching prior to deployment to ensure reliable 1250 Mbit/s optical links at 1550 nm.
