What specific module model must be deployed at the opposite end of the fiber link?

You must use a matching 1270nm-TX/1330nm-RX transceiver at the remote site so that the transmit and receive optical channels cross correctly.

Why is it critical to use single-mode fiber instead of multi-mode fiber?

Multi-mode core diameters cause severe modal dispersion at 40km, whereas single-mode fiber guarantees the signal integrity needed for long-haul laser transmission.

What parameters can I track via the DOM interface?

The DOM feature reads internal telemetry, specifically monitoring internal module temperature, supply voltage, laser bias current, TX power, and RX power.

Does this BiDi technology introduce transmission latency compared to standard dual-fiber optical modules?

No, the internal WDM filters split wavelengths purely passively at light speed, meaning single-strand Bidirectional transmission introduces zero added latency.

Are these 10G BiDi SFP+modules hot-pluggable inside an active data center distribution frames chassis?

Yes, the standard SFP+ mechanical structure allows safe, live hot-swapping without interrupting adjacent operational port links.

Does the DOM telemetry on this SFP+ transceiver provide real-time laser bias current and absolute RX power readings?

Absolutely, the built-in SFF-8472 digital optical monitoring outputs live diagnostics directly to your CLI or SNMP dashboard. This lets you monitor transceiver health, internal voltage, and dBm line degradation instantly.

Can I get a volume discount if our company buys a batch of 500 units for a campus network core project?

Absolutely. Please contact our corporate sales team directly to receive customized tiered volume pricing and bulk logistics discounts.

Do you test every individual module for bit error rate limits prior to leaving the assembly line?

Yes, 100% of our optical transceivers pass strict bit error rate and hardware compatibility loop testing before packaging.

What exact wavelength pairing do I need on the remote switch to link up with this LS-BL332710-40C module?

You need its exact complementary model, the LS-BL273310-40C, which transmits at 1270nm and receives at 1330nm. Matching a 1330nm-TX with another 1330nm-TX on a single strand will result in zero traffic synchronization.

We deployed a dozen of these 10G SFP+ BiDi 40km transceivers to connect our main office block to the remote warehouse over single-mode fiber. The 1330nm-TX and 1270nm-RX setup on a single strand LC port is awesome because it saved us the cost of leasing a second fiber line. Link has been solid for a month straight without a single drop. Highly recommend LINK-PP for cost-effective enterprise upgrades!

We ordered a bulk pack of these 10G single-strand LC optics for an indoor datacenter upgrade. Delivery took an extra day due to local customs clearance delays here in the UK. Once they arrived, the installation was dead simple—plug and play with our aggregation switches. The built-in DDM standard interface works well. Great product, but international logistics could be slicker.

Needed a fast 40km link budget fix for an unexpected fiber span expansion. The LS-BL332710-40C 10G BiDi SFP+ module worked perfectly out of the box with our current fiber setup. The built-in DDM standard telemetry reads precisely, providing stable TX/RX power fields on our monitoring dashboard. Perfect match for network engineers who need reliable single-strand solutions.

Great budget-friendly Simplex LC UPC SMF transceiver. Plugged it straight into the switch and it didn't throw any "unsupported transceiver" errors, which usually happens with generic cheap brands. The DOM interface shows clean laser levels within the standard link budget thresholds. Shipping to the US was fast too.

During our engineering validation phase, we put these modules through a series of demanding optical spectrum tests to verify laser wavelength accuracy and eye diagram integrity. The transmitter showed exceptional stability and clean eye margins under high traffic volumes. The DDM diagnostics functionality provides granular monitoring capabilities, which is a major advantage when looking to troubleshoot potential macro-bends or high-loss splicing points in the physical layer fiber plant. The robust mechanical build of the simplex LC port ensures stable connection reliability during routine maintenance. Outstanding engineering work from LINK-PP.

Tested the 40km link capability over an actual 35km single-mode fiber line with an inline optical attenuator. The receiver sensitivity stayed well within limits, and the bit error rate test came back completely clean. DDM diagnostics mapped accurately inside our switches without any custom terminal commands. Great product.

Perfect for 10G Ethernet optical transceiver deployments where fiber capacity is constrained. We used this simplex LC model to double our network capacity instantly over a single strand. The laser output is stable, and it runs well within its commercial temperature threshold under prolonged heavy workloads. A+ performance.

Using the LS-BL332710-40C for residential backhaul circuits. The digital optical monitoring feature is crucial for us because it lets our NOC track transceiver temperature and laser RX power in real-time. Completely matches SFF-8472 multi-source agreement specifications. Will definitely order another bulk lot for the next phase deployment.

Good optical performance from the LS-BL332710-40C module. It is fully backwards compatible with standard SFP+ slots and runs cleanly over our 30km single strand LC port run. My only minor complaint is that the product labels are quite small and a bit hard to read inside a dark server cabinet. I had to use a flashlight to verify the 1330nm-TX / 1270nm-RX wavelength mark. Performance-wise, it is flawless.

The installation phase went smoothly. Each module features a smooth wire bale latch that locks into standard SFP+ slots securely and ejects cleanly without putting stress on the internal ports. The Simplex LC/UPC connector surface features high-quality polish, resulting in excellent insertion loss characteristics across our entire indoor datacenter distribution network. The transceiver’s 1330nm-TX / 1270nm-RX optical structure allowed us to double our interconnect density without needing to pull new single-mode fiber cabling through our congested under-floor tray pathways. It is an exceptionally stable, industrial-grade engineering solution that delivers top-tier performance. (•‿•)

We stress-tested these units inside our main campus network core using an external bit error rate tester over an active 38-kilometer single-mode fiber span. The results showed zero bit errors and excellent receiver sensitivity margins. Crucially, the built-in digital optical monitoring framework tracks parameters like transceiver temperature, laser bias current, and real-time RX/TX power levels directly through our SNMP platform. They match SFF-8472 and SFF-8431 multi-source agreements flawlessly, ensuring perfect cross-vendor interoperability. Excellent product that saves thousands compared to OEM pricing.
