LINK-PP LS-BL332710-20I 10G SFP+ FAQ

Explore technical insights regarding the optical isolation, physical interfaces, link budgets, and deployment capabilities of this industrial-grade 10G BiDi SFP transceiver.

The transceiver incorporates high-isolation WDM filters. This optical design ensures that the strong local 1330nm transmit signal does not bleed into and overpower the weak incoming 1270nm receive signal over the same fiber.
Yes, provided the total optical budget of the 20km link is not exceeded. Every patch connection or mechanical splice introduces insertion loss, which must be factored into the overall link budget calculation.
The ultra-physical contact (UPC) polish minimizes back-reflections to ensure high signal-to-noise ratios, which is critical for error-free 10Gbps transmission over 20km.
Yes, the "I" suffix in the part number indicates an industrial-grade operating temperature range, allowing it to function reliably in harsh, wide-temperature environments.

Does exactly what it says on the spec sheet. We have about 40 of these deployed across various regional outdoor node cabinets for municipal CCTV backhaul. The industrial wide temperature range handles the summer heatwaves easily. Shipping took a few extra days to arrive in Ohio, but the performance per dollar is hard to beat.

Perfect option for local network installers. We use these for medium- and long-range multi-building links up to 20km. The simplex LC mechanism makes running neat patch fields simple. Excellent DOM functionality allows us to troubleshoot attenuation issues directly from the CLI dashboard. Very satisfied customer!

Survives extreme weather in our outdoor wireless tower cabinets! We manage rural LTE and wireless microcell sites across Canada where the winter temperatures drop way below freezing. Standard commercial-grade optics always drift in wavelength and drop the connection when it gets too cold, but these industrial-grade (-40°C to 85°C) modules haven't dropped a single packet in three months. The link holds a rock-solid 10Gbps line rate even when the outdoor cabinet gets baked by direct sunlight in the summer. It has saved our field tech team from making tons of expensive emergency driving trips out to remote sites just to reboot stuck modules.

Perfect match for 4K/8K smart city CCTV surveillance networks. We deployed these 20km BiDi transceivers across a municipal network that feeds high-resolution traffic security cameras back to a central monitoring node. Since municipal fiber allocation is strictly limited, doing bidirectional transmission over a single strand was the only way to make this project work under budget. The internal DDM tool gives us highly accurate real-time data on voltage and laser temperature, which is essential for our preventative maintenance scheduling. The signal integrity is super clean, meaning our video streams don't stutter or freeze even during peak data hours.

Excellent industrial-grade optics transceiver for FTTH/FTTB cell tower backhaul deployments. The -40 to 85°C working temperature rating is mandatory for our unconditioned remote node enclosures here. Ran a loopback stress test over 18km of single-mode fiber, zero packet drops and optical power levels remained well within budget margins. Outstanding!

Very clean performance. Optical TX power levels are right where they are supposed to be. The simplex LC/UPC link holds stable through full 10Gbps line rate stress benchmarks. The shipping tracking link was delayed by the carrier for two days, but the parts arrived safely inside static-shielded packaging. Good purchase.

The best cost-saving alternative for regional ISP distribution nodes. As a network tech for a local broadband provider, I am always looking for ways to cut infrastructure costs without sacrificing network uptime. We installed nearly 60 of these LINK-PP 10G BiDi SFP+ transceivers into our street-side distribution hubs, and we have experienced zero hardware failures or infant mortality issues so far. The modules show excellent receiver sensitivity even over longer fiber paths that have multiple inline splices and older patch panels. For any buyer who needs to balance rugged industrial build quality with a reasonable volume price, this is the best deal online.

Top-notch 10G BiDi SFP+ single-mode transceiver. We required the 1330nm-TX and 1270nm-RX configuration to align with our pre-existing simplex ISP fiber handoffs. Zero bit errors detected on our internal syslog monitoring over 48 hours of heavy continuous load tests. LINK-PP is now our official approved vendor for standard project rollouts.

We deployed these inside our industrial trackside monitoring boxes. The hardware runs rock solid through rapid temperature swings. My only complaint is that the electronic PDF documentation took a bit of hunting down on the store page, but the technical support team emailed it over within 10 minutes.

The factory-programmed compatibility on these 10G BiDi modules is incredible. Usually, getting third-party transceivers to negotiate nicely with picky telecom gear is a nightmare, but these connected at full duplex immediately. Low latency, low power consumption, and the DOM metrics match our high-end optical power meter tests.

Great reliability for linking factory automation floors over long distances. Our manufacturing plant has huge automated assembly floors with lots of heavy machinery that causes massive electromagnetic interference over traditional copper lines. We laid a 12km single-mode fiber line and used these LINK-PP industrial transceivers to connect the factory floor back to the main management office. The modules fit tightly into our hardened industrial edge switches, and the connection has been running smoothly without any lag or packet loss. It’s a very solid, ruggedly built product that can handle a lot of vibration and harsh factory environments easily.

Using these for an enterprise wireless access point backhaul aggregation layer. They pop straight into our PoE+ distribution switches without a hitch. Getting authentic SFF-8472 compliant DOM readings at this low price point saves us tons of diagnostic time. Definitely keeping these on our standard bill of materials list.

It was supposed to work before but because of the issue I faced, I made an assumption. I was wrong, but later tests I ran made me re-evaluate. Actually, your Optical Transceiver Module allows me to support alternatives that were not available previously. I do not know why it was not working initially. But I'm all to happy to have it all working now.
