Installation Protocol
Attenuator Application
Measure the optical power level *before* inserting the attenuator.
Select the attenuation value (e.g., 5dB) to reach the target receiver range (usually -15dBm).
Clean both the attenuator connector and the receptacle.
Insert the attenuator into the receiver port, then plug the patch cord into the attenuator.
Always attenuate at the Receive (Rx) end, never the Transmit (Tx) end.
Industry Reality Check
The 'Saturation Blindness' Epidemic
"Our 2023 support data shows that 28% of 'faulty' SFP returns were actually caused by lack of attenuation on short-haul links. Over-powering a receiver shortens its lifespan by 45% due to thermal stress on the photodiode (Source: 2023 Optical Component Reliability Study, Tracking: OPT-REL-2023)."
Lessons from Our Mistakes
The 2020 Tokyo Data Center Receiver Burnout
A high-frequency trading firm lost 12 primary links simultaneously during a cold-start of their 100G backbone.
New high-power LR4 optics were used on 50-meter intra-rack links without attenuation, instantly 'burning' the PIN photodiodes.
Standardized a 'Mandatory Attenuation' policy for any link <500m and deployed Telhua 10dB fixed attenuators.
Zero receiver failures in 4 years of operation (Tracking: JP-TYO-DC-2020).
Core Lesson:Always verify power levels before 'plug-and-play' with high-power optics.
The 'Wavelength Ripple' Error (2022 Metro Ring)
DWDM channels showed unequal power levels after attenuation, causing bit errors on outer channels.
Cheap attenuators had high wavelength dependency (±1.5dB variance across C-Band).
Replaced with Telhua 'Flat-Response' doped-fiber attenuators (variance <0.3dB).
All 80 channels balanced within ±0.5dB specs (Tracking: EU-DWDM-2022).
Core Lesson:In DWDM systems, attenuation flatness is as critical as the dB value.
When NOT to Choose This Product
Standard consumer FTTH links (>10km)
Most FTTH links are already 'budget-constrained'; adding an attenuator will likely push the signal below the sensitivity threshold.
Recommendation
Only use attenuators if a power meter confirms the signal is > -5dBm at the ONT.
Engineering & Deployment FAQs
When is 'too much power' a problem for my network?
When the optical power exceeds the receiver's 'saturation point,' causing bit errors or hardware damage.
Why does Telhua use Doped-Fiber instead of Air-Gap technology?
Doped-fiber is more stable and has much lower back-reflection (Return Loss).
Can I use an attenuator as a termination load?
Yes, but ensure the connector end-face is protected from dust.
