HPE H3C JL286A  Compatible QSFP+ 40G Transceiver Module | 40GBASE-LR4L 1310nm(CWDM4） 2km Duplex LC SMF Bulk Wholesale

• Operating Environment: 0°C–70°C commercial temperature range. Ensure cabinet ventilation to avoid optical power attenuation from overheating.

2.100% Compatibility Verified. Zero-Risk Deployment.

3.No Sampling. No Shortcuts. Every Unit Tested

While others rely on batch sampling, we test every single unit. Each QSFP+ transceiver is individually verified for optical compliance and continuous operational stability before it ships — so performance isn't a gamble, it's a guarantee. See the process yourself: take a virtual tour of our Test Center.

Q1: Can this HPE H3C JL286A compatible 40G QSFP+ LR4L transceiver run on mixed-brand switches for enterprise data center expansion?

A: Yes, if the module is programmed with the correct EEPROM coding matching your switch brand. Share your exact switch model and firmware version so HYTOPTODEVICE can validate compatibility before shipment.

Q2: Is it possible to install this 40G LR4L optic into QSFP28 100G ports during HPE legacy network refresh projects?

A: Often yes, when the target port supports 40G speed negotiation. Confirm port capability with your switch vendor in advance, as hardware platforms have different feature limits.

Q3: Will HPE Comware switches require firmware updates to properly detect this third-party JL286A replacement transceiver?

A: Many switches recognize standards-compliant modules immediately upon installation. Some OEM platforms require minor firmware updates or license activation to accept third-party optics from our manufacturer.

Q4: Can network system integrators pair HYTOPTODEVICE 40G LR4L transceiver with standard LR4 modules on the opposite fiber end for campus backbone links?

A: Yes, LR4L and LR4 share identical wavelengths and modulation schemes for direct interoperation. The maximum working distance will be limited to the shorter 2km reach defined by the LR4L specification.

Q5: What maximum fiber transmission distance can network planners achieve with this HPE JL286A compatible optical transceiver?

A: This transceiver supports 2 km transmission over single-mode fiber following the official 40GBASE-LR4L standard. Users requiring 10km transmission must select dedicated 40G LR4 optical transceivers.

Q6: Which CWDM wavelength bands does this custom 40G LR4L optic use for inter-building campus fiber backbone connections?

A: It uses four independent CWDM lanes at 1271 nm, 1291 nm, 1311 nm, and 1331 nm. Each lane carries 10 Gbps data, aggregating to a total bandwidth of 40 Gbps.

Q7: What operating temperature range can this bulk 40G LR4L transceiver withstand for on-site deployment by network contractors?

A: Standard commercial grade runs from 0 °C to 70 °C. HYTOPTODEVICE also provides industrial grade variants rated −40 °C to +85 °C for outdoor and harsh field environments.

Q8: Can custom network solution buyers use passive breakout cables to split this 40G LR4L module into four independent 10G data streams?

A: Passive cable breakout is not possible for this module. Each 10G lane uses unique wavelengths over the same fiber pair and requires CWDM mux/demux hardware; unlike SR4, LR4L cannot fan out directly.

Q9: Does HYTOPTODEVICE 40G LR4L transceiver support per-channel optical power readings to help field engineers perform network fault diagnosis?

A: Yes, DDM/DOM function is built into our module. Network engineers can read TX and RX power values for each of the four wavelengths through the switch CLI to check end-to-end link health.

Q10: What fiber polarity best practices should resellers follow when terminating duplex LC patch cords with this 40G LR4L transceiver?

A: Duplex LC connectors use simple A-to-B keying so polarity errors rarely occur. The main risk is swapping transmit and receive ports on one fiber end, so always verify fiber orientation during installation.

Q11: What makes 40G LR4L transceivers a better choice than DAC or AOC cables for 2km campus single-mode fiber links?

A: DAC cables only cover short distances of a few meters while AOC products rely on multimode fiber with fixed length. The HYTOPTODEVICE LR4L module is the proper option for 2km single-mode campus and inter-building fiber links.

Q12: Should I select UPC or APC fiber endface polish when matching patch cables to this 40G LR4L transceiver?

A: LR4L modules adopt UPC polish per industry standard. Your patch cords and patch panels must also use UPC; mixing UPC and APC creates high optical reflection and excessive signal loss.

Q13: Is this JL286A 40G LR4L transceiver genuine OEM hardware or a reliable drop-in replacement for wholesaler inventory?

A: OEM branded transceivers carry higher price tags with switch vendor branding. Our HYTOPTODEVICE compatible LR4L modules follow MSA standards with identical functionality and cost 60–80% less, backed by our manufacturer warranty.

Q14: What quality validation tests does HYTOPTODEVICE run on each 40G LR4L transceiver before shipping to wholesale distributors?

A: Every transceiver undergoes complete 100% factory testing. We verify TX power and RX sensitivity across all four CWDM lanes plus multi-brand switch compatibility testing; test reports can be provided on request.

Q15: What warranty protection applies to bulk procurement orders, and what is the RMA process for wholesalers with defective HYTOPTODEVICE 40G LR4L modules?

A: We provide a 5-year warranty together with a streamlined RMA workflow. Simply report the fault, return the faulty unit, and get a replacement or credit; all warranty terms should be confirmed via written order documentation.
