SFP Module InLine 32335I 1310nm Singlemode 40km 2.5Gb/s

The InLine SFP module 32335I is a singlemode fiber-optic transceiver operating at 1310 nm, supporting data rates up to 2.5 Gb/s and designed for link distances up to 40 km over singlemode fiber. Intended for use in network equipment with standard SFP slots, this module provides a compact, hot-pluggable solution for establishing long-distance optical connections between switches, routers and media converters. The form factor and electrical interface follow common SFP specifications to ensure compatibility with a wide range of devices that accept SFP transceivers.

Advantages

The module delivers stable optical transmission at 1310 nm with support for 2.5 Gb/s, enabling increased throughput on backbone and point-to-point links without requiring larger transceiver types. Its singlemode design and 40 km reach reduce the need for intermediate repeaters or amplifiers on medium-distance runs. Hot-pluggable SFP form factor allows field replacement and easy upgrades with minimal downtime. The device is a compact option for extending network reach while maintaining industry-standard physical and electrical interfaces.

Suitable for

• Backbone connections between network closets or data centers over singlemode fiber
• Point-to-point links connecting switches or routers across campus or metropolitan distances
• Integration with media converters to bridge copper Ethernet and singlemode fiber segments
• Replacing or upgrading SFP slots in managed and unmanaged network devices

Key specifications

• Optical wavelength: 1310 nm
• Fiber type: singlemode
• Maximum data rate: 2.5 Gb/s
• Maximum link distance: up to 40 km (dependent on fiber and installation conditions)
• Form factor: SFP (hot-pluggable)
• Connector type: LC duplex (typical for singlemode SFP transceivers)
• Transmission mode: duplex

How to use

Install the SFP module into an available SFP port on compatible network equipment while the host device is powered on or off according to the device manual; the hot-pluggable design permits live replacement in most systems. Connect a singlemode LC duplex patch cable between the module and the remote optical device. Verify link status and data rate in the host device management interface and confirm optical parameters such as received power and alarms if the device provides monitoring. Ensure fiber polarity and connectors are correct before powering on active endpoints.

Usage recommendations

For reliable operation, use singlemode fiber compliant with relevant ITU-T standards and high-quality LC duplex patch cords. Keep transceiver dust caps on when not in use, avoid excessive bending of the fiber, and confirm host device compatibility with 2.5 Gb/s SFP modules. If link margin or distance is critical, verify attenuation and consider fiber testing to ensure the 40 km reach under installed conditions.
