Usage Guidelines & Best Practices

1. Exclusive Single-Mode Fiber (SMF) & Wavelength Pairing

  • Exclusive SMF Compatibility: Designed strictly for OS2 Single-Mode Fiber (SMF) with LC/UPC polished connectors. Multi-mode fiber (MMF) is not compatible and will cause high insertion loss or complete link failure.

  • Mandatory Tx/Rx Wavelength Pairing: BiDi technology transmits and receives over a single fiber strand using two distinct wavelengths. Modules must be deployed in complementary pairs:

2. Hot-Swapping & Mechanical Care

  • Hot-Pluggable Support: Fully supports hot-swapping—can be safely inserted or removed while host equipment (switches/routers) is powered on without interrupting non-related port traffic.

  • Latch Mechanism: Always unlock and use the integrated bail latch to remove the transceiver. Never pull directly on the fiber cable or the body of the optical module to prevent internal optical alignment damage.

  • ESD Precautions: Practice strict Electrostatic Discharge (ESD) measures (e.g., grounding wrist straps) during field installation to protect sensitive high-speed ICs.

3. Industrial-Grade Thermal Management

  • Wide Operating Temperature Range: Rated for harsh industrial environments from -40°C to +85°C (-40°F to 185°F).

  • Enclosure Airflow: Ensure industrial enclosures or outdoor cabinets provide sufficient airflow or heat dissipation to keep the module’s real-time internal temperature within operating limits.

4. Fiber Hygiene & Optical Protection

  • Cleanliness Standard: Inspect and clean all LC fiber end-faces with a 1.25mm fiber cleaning pen or lint-free wipes before insertion. Microscopic dust is the leading cause of high attenuation and port degradation.

  • Dust Protection: Always re-install dust caps on transceiver optical ports and fiber patch cables whenever they are disconnected.

  • Short-Distance Safeguard (<2km): For short-reach testing in labs, check Digital Optical Monitoring (DOM) receiver power. Use an inline 3dB–5dB optical attenuators, if incoming power exceeds the maximum RX overload threshold to prevent photodiode damage.

5. Switch Configuration & Real-Time Monitoring

  • Port Speed & FEC Matching: Ensure the host port speed is manually set to 25G. Verify that RS-FEC (IEEE 802.3 Reed-Solomon Forward Error Correction) is enabled consistently on both endpoints, as 25G BiDi links typically require FEC for error-free performance.

  • DOM Diagnostics: Leverage real-time Digital Optical Monitoring (DOM/DDM) via your switch OS to track critical operating parameters:

    • Tx/Rx Optical Power levels

    • Module Operating Temperature

    • Laser Bias Current & Supply Voltage

FAQ
Q1: What fiber type matches H3C SFP-25G-LX-SM1270-BIDI 25G BiDi 10km modules?
A1: Our H3C-compatible BiDi transceivers strictly demand OS1/OS2 single-mode fiber, paired with simplex LC connectors. Multimode cable cannot work with our single-wavelength optical chips.

Q2: Can this 10km BiDi module be deployed for short links like 300m?
A2: Absolutely. HYTOPTODEVICE’s 10km BiDi units adopt PIN receivers that won’t saturate on short-distance fiber. Unlike long-haul ER transceivers, no optical attenuator is needed for 0–10m short cabling within H3C equipment rooms.

Q3: Can I install SFP-25G-LX-SM1270-BIDI into 100G QSFP28 ports?
A3: Yes. Just equip a QSFP28-to-SFP28 QSA adapter and enable 4x25G breakout mode on your H3C 100G switch ports to run our 25G BiDi modules normally.

Q4: What humidity range do our industrial H3C BiDi transceivers support?
A4: Standard working humidity is 5%–85% non-condensing. For outdoor cabinet deployment with our modules, use fully sealed fiber boxes to avoid water vapor condensation damaging internal components.

Q5: DDM displays Rx Power -40dBm (LOS) on H3C switches, how to troubleshoot?
A5: First verify the paired opposite BiDi module at the remote end is powered on and transmitting signals. Also check LC end-face cleanliness and full fiber continuity with our H3C matching modules.

Q6: How much insertion loss will a standard simplex LC adapter bring to H3C BiDi links?
A6: A well-cleaned LC-LC simplex adapter creates 0.2dB–0.5dB insertion loss. Multiple cascaded adapters will consume the 6.3dB power budget of our SFP-25G-LX-SM1270-BIDI and cause unstable links.

Q7: What MTBF value do our H3C industrial 25G BiDi modules achieve?
A7: All HYTOPTODEVICE SFP-25G-LX-SM1270-BIDI industrial transceivers have an MTBF exceeding 1,500,000 hours under standard lab conditions, delivering long-term stable performance for large H3C network projects.

Q8: Does H3C SFP-25G-LX-SM1270-BIDI support CPRI Option 10 5G fronthaul links?
A8: Compatible fully. CPRI Option 10 runs at 24.33Gbps, which fits the 25.78Gbps wire speed of our H3C BiDi modules, widely used for outdoor H3C base station interconnection.

Q9: Will ESD static harm the H3C BiDi module during field installation?
A9: Static discharge can permanently burn the internal laser chip of our SFP-25G-LX-SM1270-BIDI. We suggest all engineers wear certified anti-static wrist straps when plugging/unplugging modules on H3C switches and tower BBUs.

Q10: Why does H3C switch pop up "Rx Power High" alarm with our 10km BiDi transceiver?
A10: This warning only occurs on ultra-short 1m fiber jumpers. Our transmitter outputs relatively high optical power; install a 3dB or 5dB fixed attenuator to pull receiving power back to the normal working window and clear the alarm.
