We have a 35km single-mode fiber span with Duplex LC patch panels. Is this optical module a direct fit for our patch cables?

Yes, this LS-DW3110-40I 10G SFP+ module features a standard duplex LC receptacle and is designed specifically for single-mode fiber transmissions up to 40km without needing external dispersion compensation.

Does operating this DWDM module at high industrial temperatures increase its power consumption significantly?

The module runs on a standard single +3.3V power supply with optimized power dissipation. Even under full load in extreme heat, its power draw remains within standard SFP+ envelope specs, avoiding extra thermal stress on your host switch.

Can we integrate this 10G SFP module into an existing 100GHz passive DWDM MUX/DEMUX system that has a dedicated C31 port?

Yes. The LS-DW3110-40I DWDM module operates on the standard 100GHz ITU grid at C31 (1552.52nm), allowing direct connection to the C31/1552.52nm channel port of any standard passive DWDM multiplexer.

Our 5G LTE base station cabinets in Arizona reach high ambient heat during summer. Will the laser degrade or drop packets when ambient heat spikes?

Not at all. This module uses an industrial-grade cooled EML laser, specifically engineered to maintain precise wavelength stability and low bit-error rates even at the upper thermal limit of +85°C.

As an infrastructure engineer managing utility substation networks, component reliability is non-negotiable. We integrated a batch of these LS-DW3110-40I DWDM modules into our 10G backbone across multiple remote sites. The 100GHz C31 grid channel stability is crisp with tight wavelength accuracy, avoiding adjacent channel crosstalk on our passive MUX/DEMUX units. Real-time DDM telemetry integrates seamlessly into our SNMP monitoring system for proactive link health checks.

These DWDM optical transceivers pass all DOM checks and 40km link tests without a hitch, but regional carrier transit took two days longer than estimated.
