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.

For an outdoor aggregation project, we needed an industrial-temperature 10G DWDM SFP+ module rather than a standard indoor optic. These units operated reliably in sealed street cabinets where ambient conditions change fast. We used the 100GHz DWDM wavelength plan to conserve fiber capacity, and the 40km reach covered our longest span with margin. The DOM feature also gave our NOC useful visibility when checking remote optical health.

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.

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.

We recently overhauled a backhaul transport segment running between two regional distribution POPs approximately 35 kilometers apart. Using these industrial-grade 1554.94nm DWDM SFP+ modules over single-mode fiber, we observed clean optical power levels well above the receiver sensitivity threshold. The 100GHz ITU grid alignment integrates perfectly with our passive multiplexer panels, eliminating signal bleed into adjacent channels. Real-time DOM telemetry provides accurate metrics directly to our central NMS dashboard, allowing us to monitor optical RX power in real time. For mission-critical infrastructure operating in demanding conditions, this module is an unbeatable enterprise-grade option.
