Product Overview

HYTOPTODEVICE QSFP+ 40G SR4 serves as drop‑in hardware alternative for Extreme 10319 optical module. Built on 850 nm VCSEL parallel array hardware, it achieves 100‑meter reach over OM3 multi‑mode fiber and 150‑meter reach over OM4 multi‑mode fiber with MPO‑12 interface. Compliant with IEEE 802.3ba and QSFP+ MSA industry standards, pre‑loaded Extreme‑specific EEPROM delivers alarm‑free hot‑swap plus native DDM/DOM diagnostics. Well‑suited for Summit‑series leaf‑spine fabrics, core aggregation trunks and server rack uplink applications. As direct factory manufacturer and supplier, we support factory bulk wholesale orders, custom EEPROM tuning and private‑label service for global integrators and enterprise purchasers.

Usage Guidelines & Best Practices

  • Fiber Choice: Only compatible with OM3 / OM4 multi‑mode MPO‑12 trunk cabling; single‑mode fiber cannot facilitate 850 nm SR4 operation and will produce link failure.

  • Distance Limit: 100‑metre maximum operating reach on OM3, 150‑metre maximum on OM4; excessive splice joints, dirty connector end‑faces or sharp fiber bends degrade practical transmission distances.

  • 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‑plug supported; keep MPO connector end‑faces clean, observe minimum fiber‑bend radius requirements.

  • Port Configuration: Confirm host ports are set to 40G SR4 mode; do not mix SR4 with other 40G optical standards on the same link.
  • Operating Environment: Designed for commercial‑grade 0°C‑70°C ambient conditions; maintain adequate cabinet‑level airflow to prevent excessive module temperature build‑up.

For detailed operation instructions, please refer to the User Guide.

FAQ 

Q1: How do I clear unsupported‑transceiver warnings after fitting HYTOPTODEVICE QSFP+ 40G SR4 on Extreme Summit switches? A: This usually means the module's coding does not match the switch's vendor lock. Genuine‑compatible HYTOPTODEVICE modules include the right coding; if the message persists, check the port configuration, update firmware, or contact us for a recode.

Q2: Can HYTOPTODEVICE 40G SR4 work alongside existing 10G SFP+ hardware for phased Extreme network modernisation? A: Yes, with a breakout solution: the 40G SR4 can be split into 4×10G links using an MPO‑to‑4×LC breakout cable connected to SFP+ ports, letting you migrate gradually.

Q3: What fiber types are required to operate HYTOPTODEVICE Extreme‑compatible QSFP+ 40G SR4 modules? A: Multimode fiber only — OM3 or OM4 (OM5 also supported on some platforms). It will not work on single‑mode fiber; that requires a 40G LR4 module.

Q4: What typical power draw should planners account for when populating dense Extreme switch racks with HYTOPTODEVICE QSFP+ 40G SR4? A: Typically around 1.0–1.5 W per module, depending on vendor and temperature — far lower than the MSA maximum, so it is safe for dense switch line cards.

Q5: What insertion loss and link‑budget values need evaluation for HYTOPTODEVICE 40G SR4 inside Extreme‑managed fiber plant? A: The 40GBASE‑SR4 channel supports a maximum insertion loss of about 1.9 dB (including connectors and patch panels). Confirm your cable plant loss before deployment.

Q6: Will deploying HYTOPTODEVICE 40G SR4 hardware constrain future 100G upgrade plans on Extreme infrastructures? A: It is a 40G product; the fiber (OM3/OM4) can often be reused for 100G SR4/SR10, but the module and ports must be upgraded. Plan cabling with future capacity in mind.

Q7: Can existing on‑site MPO trunk cabling be reused with HYTOPTODEVICE QSFP+ 40G SR4 in Extreme network projects? A: Check the fiber count, connector polish (UPC), and polarity. Existing 12‑fiber MPO trunks are often reusable, but verify loss and polarity against SR4 requirements.

Q8: What performance trade‑offs arise when mixing OM3 and OM4 multimode fiber within one physical link using HYTOPTODEVICE 40G SR4? A: Yes, but the reach is limited by the shorter‑grade segment (OM3), so a mixed link is rated at 100 m maximum.

Q9: What compliance certificates are available for HYTOPTODEVICE factory‑bulk‑ordered QSFP+ 40G SR4 transceivers? A: Typical certifications include CE, FCC, RoHS, and REACH compliance; some suppliers also hold ISO 9001. Ask for certificates before ordering.

Q10: Are HYTOPTODEVICE QSFP+ 40G SR4 units properly ESD‑shielded for shipping and on‑site handling within Extreme deployments? A: Yes — they ship in anti‑static packaging and are designed for hot‑swap with ESD protection. Always ground yourself before handling.

Q11: What stock position and expected lead‑time apply for HYTOPTODEVICE Extreme‑compatible QSFP+ 40G SR4 factory bulk orders? A: Popular models (Cisco/Arista/Juniper‑compatible 40G SR4) are usually in stock with 24–72 h dispatch; custom‑coded or industrial versions may take 1–3 weeks.

Q12: Which payment options and international Incoterm arrangements can HYTOPTODEVICE support for cross‑border factory wholesale QSFP+ 40G SR4 procurement? A: Typical terms: T/T, PayPal, or trade assurance for smaller orders; FOB, CIF, or DDP for freight. Confirm total landed cost (shipping, duties, taxes) before finalizing.

Q13: Are there unplanned import‑related hidden fees when importing HYTOPTODEVICE QSFP+ 40G SR4 for Extreme enterprise projects overseas? A: Duties and taxes vary by destination and Incoterm. Ask the supplier to quote DDP if you want a fixed, all‑inclusive delivered price with no surprises at customs.

Q14: How can ExtremeXOS administrators retrieve real‑time optical diagnostic metrics from HYTOPTODEVICE QSFP+ 40G SR4? A: Use the switch CLI (e.g., show interface transceiver or show optics) to view per‑lane temperature, voltage, TX/RX power, and alarms — the data comes from the module's standard DOM.

Q15: Does investing in 40G SR4 still deliver tangible business value amid industry transition toward 100G / 400G speeds for Extreme environments? A: For existing 40G networks it remains fully supported and cost‑effective; your multimode cabling can often be reused later. Choose suppliers with long‑term availability so you can restock for years.
