What is the maximum transmission distance of the SFP-10G-BX80-I module?

It supports up to 80km over single‑mode fiber (SMF) with a simplex LC connector.

Do I need two separate fibers for TX and RX?

No, it’s a BiDi SFP module – it uses only one fiber for both transmit and receive.

Which wavelengths does the SFP-10G-BX80-I 10G SFP+ use?

It transmits at 1550nm and receives at 1490nm. You must pair it with a module that does the opposite (TX 1490nm / RX 1550nm).

What happens if I connect it to a wrong BiDi SFP module (e.g., both with TX 1550nm)?

The link will not work because both ends would transmit on the same wavelength. Always pair TX 1550nm/RX 1490nm with TX 1490nm/RX 1550nm.

Since this specific model transmits at 1550nm and receives at 1490nm, what exact part number do I need for the opposite side of the 80km link?

You will need the matching companion module that transmits at 1490nm and receives at 1550nm to establish a proper bidirectional optical link.

Can the LS-BL554910-80I report real-time DDM metrics like Tx/Rx power on standard enterprise aggregation switches?

Yes, the module features built-in DOM/DDM that syncs automatically with host platforms to show precise optical power levels and temperatures.

Does the module housing offer adequate shielding against electromagnetic interference in industrial environments?

Yes, the ruggedized zinc alloy housing provides excellent EMI shielding and physical protection for harsh industrial deployments.

Faced with severe fiber strand scarcity between our primary data center and a secondary colocation facility 55km away, we implemented a single-strand transport design using these 10G BiDi SFP+ modules. Utilizing the 1550nm/1490nm channel separation allowed us to reclaim half of our patch infrastructure for redundancy pathways. The optics adhere perfectly to standard multi-source agreements, ensuring broad multi-vendor hardware compatibility across our routing platforms. Physical installation was seamless, and the latching mechanism provides clear tactile feedback when locked into the port.

Cellular backhaul networks require absolute link availability. We integrated these industrial-spec 10G BiDi modules into our regional cell site aggregation paths. The optical performance over our 70km single-mode fiber runs has been exemplary. We monitored the physical link parameters closely during initial provisioning; the transmitter spectral width and side-mode suppression ratio are excellent, preventing dispersion penalties over long distances. The ruggedized casing provides peace of mind for long-term outdoor deployment.

Flawless link, documentation was a bit sparse. Technically, these are superb. We're running them on a 65km link, and DDM readings are excellent. My slight reduction in stars is for the documentation; we had to search online to confirm the compatibility commands for our specific switch vendor, rather than having them clearly listed. Once configured, though, they've been perfect. ✨

We needed to deploy a 10G transport network across several remote campus sites but were limited by available fiber strands. These 1550nm-TX/1490nm-RX simplex modules saved the day by utilizing just a single core. The links have been up continuously without any physical layer errors.

Deploying active network components in unconditioned outdoor environments requires strict compliance with industrial temperature parameters. We installed a batch of these industrial-grade 10G SFP transceivers into hardened roadside switches for an intelligent transportation system network. Throughout extreme ambient temperature swings, the modules showed no signs of wavelength drift or transmitter degradation. The physical layer link remained completely solid without any frame alignment errors or link flaps, confirming that the internal optical alignment can handle demanding thermal stresses.

These 80km BiDi SFP optical transceivers provide excellent signal launch power. We tested them across several legacy fiber paths with high splice counts, and they still maintained an adequate optical power margin over the entire distance.

Finding reliable long-range 10G SFP+ modules that actually meet their optical budget can be tough. These BiDi optics hit the 70km target over our single-mode fiber infrastructure easily. The signal attenuation margins remain well within acceptable parameters.

Performance is great, customs paperwork was a headache. Zero complaints about the transceiver's 10G link stability over our 70km fiber run. They integrated effortlessly with our core routers. We did, however, have a bit of a back-and-forth with the courier over customs declarations, which delayed deployment for a couple of days. The product is spot on, but the logistics had a few bumps.
