Usage Guidelines & Best Practices
-
Fiber Choice: Works only with OS2 single-mode fiber. Multimode fiber is not compatible with this 1310nm CWDM4 module.
-
Optical Attenuator Required for Short Links: For testing or short-distance connections (<15km), connect a 10dB–15dB optical attenuator to the RX port to prevent damaging the receiver.(15KM
-
Cleanliness & Dust: Keep dust caps on whenever unattached. Clean fiber end-faces with a optical cleaning pen before insertion; dust causes over 80% of optical link failures.
-
Installation Specification: Hot-swap supported. Follow ESD anti-static procedures and keep LC connectors clean for stable links.
- Mode Setting: Configure 40G port speed via switch CLI. This ER4 module does not support breakout to 4×10G.

The Core Feature
1. 40G QSFP+ Connectivity for Low-Power Data Centers
Combining low power consumption, high port density, and high-speed performance, the QSFP+ transceiver gives you a fast, cost-effective route to 40G transmission — no big footprint required.
2.No Guesswork. No Downtime. Pre-Tested for Your Switch.
A mismatched module doesn't just slow you down — it kills your link and burns your deployment hours. That's why every 40G QSFP+ ER4 module is compatibility-tested in the target switch environment before it ships. What arrives at your rack is a module already proven to work: clean link-up on the first plug-in, zero surprises, zero downtime. See the verification for yourself:

3.Every Unit Passes Before It Ships. Not Just a Sample.
A sample is a guess about the batch. An individual test is proof about the unit. Each QSFP+ ER4 transceiver is individually verified for optical compliance and continuous operational stability before shipping — zero reliance on sampling, zero shortcuts. What you install is what we proved. Performance: guaranteed, not gambled. Curious how? Tour the

FAQ
Q1: I deploy Arista, Juniper or Huawei network hardware. How can I verify optic compatibility before site installation?
A: Yes, we can complete pre-compatibility verification for your Arista, Juniper or Huawei hardware. HYTOPTODEVICE programs our 40G QSFP+ ER4 with switch-specific EEPROM; share your exact switch model and firmware version, and our engineers confirm matching before shipment to avoid on-site incompatibility.
Q2: Is it possible to run this transceiver inside a QSFP28 100G port on my existing network infrastructure?
A: It is possible to use this 40G QSFP+ ER4 inside a QSFP28 port if your hardware supports 40G speed negotiation. Most modern 100G QSFP28 ports support downspeed to 40G, but port capability varies by vendor, so confirm your switch specification before ordering.
Q3: Should I check my network device firmware version before purchasing this optical module?
A: It is recommended to review your switch firmware release prior to purchase. Many platforms recognize HYTOPTODEVICE 40G QSFP+ ER4 out of the box, while certain OEM devices require a firmware update to accept third-party optics and prevent transceiver alarms.
Q4: What fiber cable specification does this optic require, and will it work on my existing fiber plant?
A: This 40G QSFP+ ER4 transceiver requires OS2 single-mode fiber for full 40km transmission. It cannot operate on multimode fiber; if your existing cabling is OS2 SMF, it will function normally, while OM series multimode fiber only supports short-reach SR modules.
Q5: What fiber connector interface does this module use, and do I need matching fiber patch leads?
A: This HYTOPTODEVICE 40G QSFP+ ER4 requires duplex LC fiber connectors. You will need duplex LC terminated single-mode patch cords; cables with MPO or SC connectors cannot plug directly into this module and will require adapter conversion.
Q6: Does this 40G optical transceiver support DDM/DOM functions for continuous link performance inspection?
A: Yes, our 40G QSFP+ ER4 fully supports DDM/DOM real-time monitoring. It reports per-wavelength temperature, supply voltage, transmit and receive optical power through the switch interface, allowing continuous remote link diagnostics for your network.
Q7: What compliance and import certification documents come with this 40G QSFP+ ER4 optical transceiver?
A: HYTOPTODEVICE 40G QSFP+ ER4 transceivers are manufactured with RoHS compliance and meet IEEE and MSA industry standards. We can supply certification documents including test reports and compliance certificates for your import and project audit requirements.
Q8: Will the laser and TEC components maintain stable performance across the entire 40km transmission range for long-term operation?
A: The integrated laser and TEC components maintain stable performance for the full 40km rated distance. Every HYTOPTODEVICE module undergoes 72-hour burn-in and temperature cycling testing, reducing long-term drift and ensuring consistent optical output over years of operation.
Q9: What secure payment options are available to safeguard overseas buyers during cross-border optical module orders?
A: We offer secure international payment channels for overseas buyers. HYTOPTODEVICE accepts T/T bank transfer and other trade-friendly payment terms, and we can issue formal proforma invoices to protect your procurement funds and order records during cross-border transactions.
Q10: Is the cost premium of ER4 optical modules compared to LR4 optics justified for my network security project?
A: The higher cost of ER4 versus LR4 is justified only when you need transmission beyond LR4’s maximum 10km limit. HYTOPTODEVICE 40G QSFP+ ER4 supports up to 40km OS2 links; if your fiber span stays under 10km, LR4 will deliver the same link quality at lower cost.
Q11: Can I request sample modules or limited trial batches before committing to large bulk transceiver procurement?
A: Yes, HYTOPTODEVICE accepts sample and small trial orders for this 40G QSFP+ ER4 module. We support low MOQ sample testing so buyers can validate compatibility and link performance before placing large bulk factory wholesale orders.
Q12: Are industrial wide-temperature ER4 transceivers available if my deployment runs under harsh temperature environments?
A: Industrial temperature grade 40G QSFP+ ER4 can be provided as a custom option. Our standard commercial model works within 0~70°C, while industrial versions support -40~85°C, subject to custom EEPROM programming and extended lead time.
Q13: What return and refund terms apply to optical transceiver purchases from HYTOPTODEVICE?
A: Our return and refund rules follow the stated terms for transceiver orders. Unopened HYTOPTODEVICE 40G QSFP+ ER4 modules are returnable within the defined time window; defective units covered by warranty qualify for replacement or refund, and full written terms will be shared before order confirmation.
Q14: What kinds of technical files can your team provide for customers to review before finalizing purchase orders?
A: We supply complete technical documents upon request before purchase. HYTOPTODEVICE can provide datasheets, specification sheets, test reports and compliance certificates for this 40G QSFP+ ER4 to support your network design and procurement review.
Q15: How do you resolve compatibility issues found after the optical module has been installed on firewalls or switches?
A: We provide targeted technical support to resolve post-installation compatibility problems. Our engineering team can rework EEPROM coding remotely or arrange module replacement for confirmed hardware incompatibility, following our quality and after-sales process for bulk buyers.
