Can we drop this C25 1557.36nm DWDM transceiver straight into an existing passive 100GHz ITU grid MUX/DEMUX tray without tuning optical frequencies?

Yes, the cooled EML laser is factory-locked to the exact 1557.36nm wavelength (C25 channel) on the 100GHz grid, requiring zero frequency tuning.

Does this LS-DW2510-40I DWDM module plug directly into standard LC duplex patch cables on our 100GHz passive MUX/DEMUX unit?

Yes, the module features a standard duplex LC receptacle that mates directly with standard single-mode LC fiber patch cords.

Will inserting or pulling this hot-pluggable DWDM module cause link flaps on adjacent active ports during emergency slot upgrades?

No, the hot-pluggable SFP+ footprint incorporates standard electrical isolation safeguards to ensure live swapping never impacts neighboring port traffic.

Does the transmitter laser experience optical frequency drift or power drop-off when the internal cabinet temperature spikes?

No, the integrated cooled EML laser actively maintains exact 1557.36nm ITU grid alignment across the full -40°C to +85°C industrial operating temperature range.

Does chromatic dispersion degrade the optical signal over a maximum 40km single-mode fiber run?

No, the cooled EML laser minimizes wavelength chirp, delivering strong extinction ratios and clean eye diagrams to overcome chromatic dispersion across 40km spans.

We used the LS-DW2510-40I 10G DWDM module in a metro fiber extension between two office sites. The duplex LC connection was simple, DOM values looked normal from day one, and the 1557.36nm wavelength matched our existing 100GHz DWDM plan perfectly.

The 10G DWDM SFP+ modules worked correctly in our compatibility test and the DOM readings were available as expected. Pricing was reasonable for an industrial 40km optic, although we would like stronger quantity-break pricing for repeat orders.

Ordered these optical modules for a multi-site campus fiber network where we needed fixed DWDM wavelengths instead of adding more active transport gear. The 40km 10G SFP+ optics were recognized correctly after using the required OEM-compatible coding. Nice option for keeping the BOM under control.

The industrial temperature range support made this DWDM module a suitable option for our cabinet deployment. One outer carton had a small dent during transit, but the inner packaging was intact and all modules tested normally.

Upgraded our campus backhaul to 10G DWDM over single-mode fiber using these SFP+ modules. Plugged duplex LC patches into our core switches and got immediate link-up at full 10Gbps line rate. Very clean signal integrity across a 32km span.

We needed C25 100GHz grid optics for our 40km passive DWDM MUX/DEMUX system. The optical budget on these 10G SFP+ DWDM modules is right on target, delivering around 1dBm launch power. The link budget came in well under our BER margin. Will definitely order more for our next node deployment.

Performance on our single-mode fiber link is good, and the duplex LC connectors were clean. Shipping took a little longer than our project schedule preferred, but the transceivers themselves were stable once installed.
