At the physical layer, both wavelengths share an identical 9µm single-mode fiber core diameter, making their insertion loss sensitivity to microscopic contamination functionally equal. To maintain your link budget margins, we strictly recommend scoping and cleaning the ferrule tips with an optical click-cleaner immediately prior to insertion. By

High-performance storage replication over 18km single-mode fiber. We migrated our disaster recovery site to a new facility exactly 18km away from our primary data center. We utilized these 10G CWDM 1370nm transceivers to link our primary SAN to the backup replication target. Despite pushing close to the 20km maximum rating on a standard single-mode fiber path, we have experienced absolutely zero frame errors, sync drops, or link flapping. The data throughput is a steady, unthrottled 10Gbps. Couldn't have asked for a better, more cost-effective replication link setup.

Perfect solution for expanding fiber capacity in municipal networks. Our municipal WAN was running out of dark fiber pairs between the city hall and the public safety building. Instead of embarking on a costly trenching project, we deployed a passive CWDM system utilizing these 10Gbps 1370nm SFP+ optics. The 20km range provided a massive optical budget safety margin over our 14km actual run distance. The transceivers fit perfectly into our standard SFP+ ports and deliver immediate full-duplex throughput.

Excellent choice for campus network core distribution upgrade. Our university network team recently overhauled the distribution layer across 4 separate campus locations. We leveraged these 10G SFP+ CWDM 1370nm transceivers to consolidate traffic into our primary data center over a 15km single-mode fiber ring. The duplex LC interface provides clean, low-insertion-loss connectivity. Even with multiple intermediate optical patch panels, the signal margin remains highly conservative. This deployment has significantly reduced our packet jitter during peak student registration hours. Highly recommended for any institutional IT infrastructure overhaul.

Our network validation lab put these commercial-grade modules through a rigorous battery of tests, including thermal cycling from 5°C up to 65°C and optical back-to-back testing. The internal laser driver demonstrated excellent wavelength stability, locking perfectly onto the 1370nm CWDM grid without drifting under thermal stress. The duplex LC interface maintained consistent insertion loss characteristics through 50 mating cycles. For system integrators looking for dependable 10G SFP+ fiber components, this product gets an absolute pass grade.
