Will integrating this C28 optic into an existing 100GHz grid cause spectral bleed into neighboring channels?

No. Strict ITU-T C28 wavelength locking keeps optical power tightly contained within its allocated channel slot, preserving clean sideband margins.

We are retrofitting older 10G aggregation hardware — will hot-swapping this LS-DW2810-40I DWDM SFP+ interrupt neighboring active ports?

No, the module features true hot-pluggable electrical isolation, letting you insert or swap it live without causing link flaps on adjacent ports.

Will the optical output wavelength drift off C28 (1554.94nm) when cold-starting at sub-zero temperatures?

No, internal laser temperature stabilization maintains tight 100GHz ITU channel accuracy even down to -40°C.

Can we use a standard duplex LC OS2 optical patch cord to jumper this module into our passive DWDM Mux panel?

Yes, it features a standard duplex LC receptacle that pairs directly with standard single-mode optical patch cables.

Multiplexing multiple 10G links over our existing single-mode fiber trunk saved us from running extra optical cabling. These 10G DWDM optical modules deliver stable performance for long-range enterprise transport networks.

This industrial-grade 10G DWDM module went into a roadside network cabinet for a backhaul project. The −40 to 85°C temperature range was the main reason we selected it, but the optical power readings in DOM have also been very useful during acceptance testing.

Good overall order experience. The box was secure, although one small carton had a slightly pressed corner from shipping; the transceiver itself was fully protected and ready for installation.

Needed hardened modules rated for extreme environment deployment in remote cabinet sites. The industrial operating temperature specs on this 40km DWDM transceiver held up through tough conditions without thermal throttling or optical power drift.

Deploying high-density optical gear inside unheated or non-air-conditioned roadside cabinets presents constant thermal challenges. We fielded a batch of these industrial-grade 10G DWDM modules across several field sites where ambient temperatures fluctuate drastically throughout the day. The optics maintained steady laser output power and tight wavelength stability on C28 (1554.94nm) without experiencing thermal frequency drift. Having reliable DDM diagnostics exposed directly via SNMP helped our network operations center monitor operating metrics remotely during heat waves. Highly recommended for field engineers building ruggedized fiber backhauls.

Used these 1554.94nm C28 DWDM modules with the passive Mux/Demux unit. The 100GHz ITU channel spacing is spot-on with zero crosstalk observed across adjacent ports. Will definitely purchase more for our upcoming regional network expansion.

Good fit for a metro access DWDM deployment. We needed the fixed 1554.94nm wavelength on a 100GHz grid, and this DWDM SFP+ module stayed stable after several weeks of traffic.
