Description

Arista QSFP-100G-PSM4 Compatible 100G QSFP28 Transceiver | PSM4 1310nm 500m MPO SMF | HYTOPTODEVICE

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: Will HYTOPTODEVICE PSM4 QSFP28 work on Cisco, Arista, Juniper and Dell network switches?

A: Compatibility relies on customized EEPROM identity coding. HYTOPTODEVICE can pre-program this PSM4 optic with vendor-specific data for Cisco, Arista, Juniper or Dell, letting modules pass hardware authentication without "unsupported transceiver" pop-ups.

Q2: Can I directly interconnect 100G PSM4 with CWDM4 or LR4 transceivers via fiber?

A: Interconnection is impossible due to different optical structures. PSM4 transmits four parallel 1310 lanes over MPO multi-fiber cables, while CWDM4/LR4 multiplex multiple wavelengths onto duplex LC fiber. Their fiber interfaces and lane designs cannot match.

Q3: Can this Cisco-compatible PSM4 be inserted into traditional 40G QSFP+ ports?

A: It cannot run normally despite identical physical shape. QSFP+ ports only support 40G signal processing hardware, lacking the DSP needed for 4×25G PSM4 parallel transmission.

Q4: Does HYTOPTODEVICE 100G PSM4 support industry-standard FEC correction?

A: RS-FEC (IEEE 802.3bj Clause 91) is fully supported. You need to enable FEC on the corresponding switch port to reach the specified ultra-low BER (< 10⁻¹²).

Q5: Can I plug blue UPC MPO patch cords into this PSM4 module’s APC port?

A: UPC cables are forbidden. This PSM4 adopts 8° APC green ports; UPC flat connectors create severe back reflection, distorting signals and scratching internal optical components permanently.

Q6: Do I need optical attenuators for 1–5m short fiber runs to prevent receiver overload?

A: Extra attenuators are unnecessary. HYTOPTODEVICE factory calibrates transmit power with sufficient safety margin, and short-distance cables will not saturate receiver chips.

Q7: Can this PSM4 module run stable links beyond 500m using ultra-low-loss single ribbon fiber?

A: Not recommended for production deployment. Even premium fiber cannot offset cumulative attenuation and lane skew over 500m, exceeding the MSA-defined power budget and triggering unstable BER.

Q8: Is 100G to four independent 25G SFP28 breakout achievable with this PSM4 optic?

A: Yes. Its four physically separated 25G single-mode lanes support matched MPO breakout cables, splitting one 100G port into four independent 25G server uplinks to maximize switch port efficiency.

Q9: Why choose HYTOPTODEVICE 100G PSM4 instead of 100G LR4 for intra-data center links?

A: PSM4 features simpler internal components, lower unit cost and ≤3.5W power consumption compared to long-reach LR4. It is the optimal high-density choice for all rack-to-rack connections under 500m.

Q10: In which scenarios is CWDM4 more cost-effective than large-scale PSM4 deployment?

A: CWDM4 delivers lower total cost for long cross-building links or projects requiring small fiber counts. The high cost of MPO ribbon cables will offset the savings from cheaper PSM4 modules in such cases.
