SFP optical transceiver InLine 32335G 1550nm singlemode 120km 1.25Gb/s

InLine 32335G is an SFP optical transceiver designed for singlemode fiber links at a wavelength of 1550 nm. The module supports data rates up to 1.25 Gb/s and is specified for reaches up to 120 km, making it suitable for long-distance point-to-point connections between buildings or across metropolitan and regional networks. The compact, hot-pluggable SFP form factor fits standard SFP ports and provides a straightforward way to add singlemode fiber uplinks to switches, media converters, routers and other network equipment.

Advantages

The transceiver provides stable single-channel transmission over long distances with low power consumption and industry-standard SFP interoperability. Its 1550 nm wavelength and singlemode optics enable enhanced reach compared with multimode solutions, while the hot-pluggable design allows insertion or replacement without shutting down the host device. The module is suitable for telecom and carrier-grade applications where reliable fiber links and predictable optical performance are required.

Suitable for

• Long-distance point-to-point fiber connections (up to 120 km)
• Fiber uplinks for switches, routers and media converters
• Telecom, ISP and carrier networks requiring singlemode links
• Site-to-site connectivity between campus, data center or remote facilities

Key specifications

• Form factor: SFP (hot-pluggable)
• Optical wavelength: 1550 nm
• Fiber type: singlemode
• Maximum link distance: up to 120 km (dependent on fiber type and link margin)
• Data rate: up to 1.25 Gb/s
• Connector type: standard singlemode fiber connector (LC/SC depending on host)
• Optical interface: single-channel transceiver optimized for long-reach transmission

How to use

Power down is not required for installation; simply insert the SFP transceiver into a compatible SFP port on the host device until it seats firmly. Ensure the host device supports 1.25 Gb/s SFP modules and configure the network interface as required by your equipment. Use singlemode fiber patch cords and appropriate connectors for the chosen port type. Verify optical power levels and link status after insertion and perform any necessary link configuration on the connected devices.

Usage recommendations

Install the module in clean conditions and avoid touching the optical connector endface. Use fiber cleaning tools before connecting patch cords. Check the host device compatibility list for supported SFP modules and monitor optical receive power to ensure sufficient link margin for the required distance.
