A:
Because the EML transmitter output power ranges from -1 to +2 dBm and receiver overload threshold is 0.5 dBm, connecting the transceiver directly on a short patch cord without attenuation risks saturating or damaging the PIN receiver. We recommend using a minimum 5dB to 10dB fixed optical attenuator during benchtop testing to keep RX power safely within the recommended operational range of -16 to -1 dBm. By

The integrated EML (Electro-absorption Modulated Laser) transmitter on 1546.92nm offers superior chromatic dispersion tolerance compared to standard DFB lasers. For standard G.652 single-mode fiber runs up to 40km at 10G rates (typical dispersion ~800 ps/nm at 1550nm), no external Dispersion Compensation Module (DCM) is required. If extending spans beyond 40km with optical amplifiers (EDFA), dispersion compensation planning should be applied. By

The LS-DW3810-40I strictly adheres to SFF-8472 SFP+ MSA standards for DDM/DOM memory mapping. Internal sensors measure real-time parameters—including TX power, RX optical power, laser bias current, module operating temperature, and supply voltage. These values are readable standardly across Arista EOS, Juniper Junos, Mikrotik RouterOS, and Dell FTOS via standard CLI commands. By

Yes, the module supports data rates up to 10.7 Gbps and is fully compliant with CPRI (Option 7/8 up to 9.8304 Gbps) and eCPRI standards. Combined with its industrial temperature range (-40°C to 85°C), it is specifically engineered for outdoor base station fronthaul and harsh radio site deployments. By

A:
Yes, it can function over a direct point-to-point single-mode fiber (SMF) link without a MUX, provided both ends use identical DWDM optics tuned to compatible wavelengths or broadband receivers. However, to utilize its precise 100GHz ITU grid C38 (1546.92nm) channel spacing properly and combine multiple signals onto a single fiber pair, it is best paired with a dedicated 100GHz C-band DWDM MUX/DEMUX.

Replaced legacy OEM optics in our remote substation automation network with these LINK-PP industrial SFP+ modules. The -40 to +85°C temperature envelope is vital for utility substations. The DDM capability provided immediate verification of optical power levels (-11.2 dBm RX over 27km), making commissioning effortless for our field technicians :-)

Deployed these 10.7 Gbps DWDM optics in an enterprise storage network between main and DR sites. Compatibility across mixed vendor gear—specifically Brocade Fibre Channel switches and Cisco Nexus platforms—was seamless out of the box. DOM data feeds clean telemetry into our Zabbix dashboard, tracking temperature, supply voltage, and optical RX power level. No firmware recoding required, fully compliant with SFP+ MSA specs.

Product performance is excellent on our 30km 10G DWDM link, but the outer shipping box arrived slightly crushed. Optics inside were well protected in ESD foam and worked fine, but packaging could be sturdier.

Our network team deployed 12 units of these C38 10G DWDM optics for metro dark fiber ring protection. The LC duplex connection latches firmly, and optical receiver overload protection (0.5dBm max) gave us peace of mind when testing short patch cords without inline attenuators. Flawless bit error rate test (BERT) results across all spans up to 35km.

As an ISP network engineer, finding reliable industrial-grade optics for unheated roadside enclosures in northern regions is tough. The -40 to 85°C operating temperature rating on these LINK-PP transceivers is genuine. We have two units driving a CPRI link for base station backhaul in an outdoor cabinet. During winter sub-zero drops, optical power stability remained completely flat. DDM telemetry reports laser bias current and housing temp without any glitching. Extremely reliable hardware for critical infrastructure ;)

We deployed eight LS-DW3810-40I modules across a 36km single-mode fiber span connecting two municipal data centers. Operating on DWDM Channel 38 (1546.92nm), these transceivers fired up immediately inside our Dell S5248F-ON switches. Real-time DDM/DOM diagnostics registered TX power at +0.5 dBm and RX power at -12.4 dBm, well within the -16 to -1 dBm receiver sensitivity range. The optics have been running 24/7 for three months under heavy traffic load with zero CRC errors. Highly recommended for cost-effective 10G DWDM link deployment.

Upgraded our high-speed 10G NAS links across a multi-building university campus spanning 22km. Using these 1546.92nm modules on existing SMF cabling allowed us to double our link capacity over DWDM without pulling new fiber lines. Receiver sensitivity of <-15.5dBm gave us plenty of margin even through two patch panels and optical splitters. Couldn't ask for a better price-to-performance ratio =D
