Product Overview
This 100G PSM4 QSFP28 is a 1:1 drop-in replacement for Arista Networks QSFP-100G-PSM4.
It works seamlessly on all Arista EOS leaf and spine switches without authentication errors.
This parallel single mode optic uses four independent 25G lanes at 1310nm wavelength.
It supports stable 500m transmission over MPO-12 OS2 single mode ribbon fiber.
No CWDM multiplexer design cuts signal loss and simplifies dense rack MPO wiring.
Each unit comes with pre-flashed Arista OEM EEPROM to eliminate "unsupported transceiver" logs.
Built-in RS-FEC correction and full DDM real-time monitoring ensure ultra-low BER performance.
Top use cases: leaf-spine fabric, rack trunk, server uplink and 100G to 4×25G breakout deployment.

Usage Guidelines & Best Practices

• Fiber Matching Rule: Only MPO-12 APC 8° angled OS2 single-mode ribbon fiber can be used; OM3/OM4 multimode fiber or UPC polished MPO cables will trigger link failure and hardware damage.
• Lane Polarity Control: Confirm MPO fiber lane sequence and polarity match before powering on ports; misaligned lanes lead to severe receive power imbalance and continuous packet loss.
• Distance Restriction: Stable performance is only guaranteed within the standard 500m MSA rated range; extended fiber routes bring excess lane skew and optical attenuation.
• Hot-Plug Support: Modules support live insertion and removal; regularly clean MPO APC end faces to eliminate dust-induced signal distortion.
• Operating Environment: Limit deployment to indoor 0°C–70°C data center environments; avoid fully sealed cabinets with poor ventilation causing persistent overheating.

FAQ

Q1: Can HYTOPTODEVICE Q28-100G-PSM4-IR PSM4 optic run normally on Dell, Cisco, Arista and Juniper enterprise switches?
A: Stable cross-platform performance depends on customized vendor EEPROM coding. We can pre-flash Dell OS10 matched ID data for this 100G QSFP28, so it passes Dell hardware authentication without unsupported transceiver warning alerts. Custom coding for other brands is also available.

Q2: Can I make optical links between Q28-100G-PSM4-IR and CWDM4 / LR4 QSFP28 modules?
A: Direct fiber interconnection cannot work. PSM4 transmits four parallel 1310 lanes via MPO multi-fiber ribbon, while CWDM4/LR4 stack multiple wavelengths on duplex LC cable. Their optical layout and physical connectors are completely incompatible.

Q3: Is this Dell compatible Q28-100G-PSM4-IR pluggable into old 40G QSFP+ switch ports?
A: It cannot operate normally despite identical outer shape. QSFP+ hardware only supports 40G signal processing and lacks DSP for 4×25G PSM4 parallel transmission. Port initialization will fail completely.

Q4: Does Dell Q28-100G-PSM4-IR 100G PSM4 support standard RS-FEC error correction?
A: IEEE 802.3bj Clause 91 RS-FEC hardware decoding is fully integrated. You must enable FEC on corresponding Dell OS10 switch ports to hit the specified ultra-low BER (< 10⁻¹²).

Q5: Can blue UPC MPO patch cords be used on this APC green PSM4 module port?
A: Using UPC cables is strictly forbidden. Flat UPC polish generates heavy light back reflection, distorts parallel signals and scratches internal laser parts permanently.

Q6: Do optical attenuators needed for 1–5m short MPO fiber to prevent receiver overload?
A: Extra attenuators are unnecessary. Factory calibrated transmit power holds full safety margin for short patch cable scenarios, receiver chips will not get saturated damaged.

Q7: Can Q28-100G-PSM4-IR run stable links over 500m with ultra-low-loss OS2 ribbon fiber?
A: Not recommended for production data center deployment. Over 500m exceeds MSA designed optical budget and lane skew compensation range, causing fluctuating BER and intermittent port flapping.

Q8: Does this Dell 100G PSM4 QSFP28 support 100G to four independent 25G SFP28 breakout links?
A: Full breakout function supported. Four physically isolated optical lanes cooperate with MPO breakout cables, splitting one Dell 100G port into four separate 25G server uplinks to improve switch port efficiency.

Q9: Why choose Dell compatible Q28-100G-PSM4-IR PSM4 instead of long-reach 100G LR4 transceivers?
A: For intra-data center links under 500m, PSM4 has simpler internal structure, lower bulk cost and ≤3.5W power consumption. It is the most cost-effective high-density parallel optic for Dell rack-to-rack fabric connections.

Q10: In which network scenarios will CWDM4 duplex LC modules beat mass PSM4 deployment on total cost?
A: CWDM4 saves overall expenditure for long cross-building links or projects with small fiber counts. High-priced MPO ribbon cables will offset the unit cost advantage of Q28-100G-PSM4-IR PSM4 modules.
