SFP module InLine 32335E 1310 nm singlemode 40 km 1.25 Gb/s

InLine 32335E is an SFP fiber transceiver module designed for singlemode networks operating at a 1310 nm wavelength. Supporting 1.25 Gb/s data rate and a maximum reach of up to 40 km, this compact hot-pluggable module is intended for installation in switches, routers and media converters to provide point-to-point optical links over long distances. The module follows the SFP form factor and is suitable for network environments that require stable Gigabit-capable fiber connectivity across campus, metro or enterprise backbone segments.

Advantages

The module offers stable singlemode transmission at 1310 nm with a 40 km reach, enabling long-distance connectivity without intermediate active components. Its SFP form factor provides flexibility and easy replacement or upgrade of optical interfaces on compatible equipment. The 1.25 Gb/s data rate supports Gigabit Ethernet and other serial optical protocols, while the hot-pluggable design simplifies maintenance and reduces downtime.

Suitable for

• Long-distance point-to-point fiber links between buildings or sites
• Campus and metro backbone connections requiring singlemode optics
• Integration with switches, routers and media converters that accept SFP transceivers
• Enterprise network segments where reliable Gigabit fiber connectivity is needed

Key specifications

• Optical type: singlemode fiber
• Wavelength: 1310 nm
• Maximum reach: up to 40 km (dependent on fiber and link budget)
• Data rate: 1.25 Gb/s (Gigabit class serial optical)
• Form factor: SFP (small form-factor pluggable), hot-pluggable
• Connector interface: standard SFP duplex optical interface (LC compatible on host transceiver slot)

How to use

Insert the SFP module into a compatible SFP port on your switch, router or media converter while the host device is powered according to the equipment manual. Connect singlemode fiber using appropriate LC connectors and ensure correct transmitter/receiver orientation. After insertion, verify link status through the host device management interface or status LEDs and confirm negotiated data rate and link integrity. For best performance, check fiber type, attenuation and connector cleanliness before establishing the link.

Usage recommendations

Use singlemode fiber with appropriate attenuation and splicing quality to achieve the 40 km reach. Clean optical connectors before mating, follow electrostatic discharge precautions when handling the module, and verify compatibility with the host device’s SFP support list or interface specifications before deployment.
