Description

EdgeCore ET7402-PIR4 Compatible 100G QSFP28 Transceiver | PSM4 1310nm 500m MPO SMF | HYTOPTODEVICE

Product Overview

This 100G PSM4 QSFP28 is a 1:1 drop-in replacement for Huawei QSFP28-100G-PSM4.

It works seamlessly on all Huawei CloudEngine leaf and spine switches without authentication errors.

This parallel single mode optic uses four independent 25G lanes at 1310nm.

It supports stable 500m transmission over MPO-12 OS2 single ribbon fiber.

No CWDM multiplexer design cuts signal loss and simplifies dense rack MPO wiring.

Each unit comes with pre-flashed Huawei 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 Huawei QSFP28-100G-PSM4 parallel optic support remote real-time optical parameter reading on CloudEngine switches?

A: Yes. HYTOPTODEVICE Huawei QSFP28-100G-PSM4 fully meets MSA standards with built-in DDM/DOM function, enabling real-time monitoring of transmit power, receive power, operating temperature, laser bias current and supply voltage.

Q2: Will the HYTOPTODEVICE zero-alarm Huawei 100G PSM4 QSFP28 automatically reduce bandwidth when connected to low-speed network ports?

A: No. HYTOPTODEVICE Huawei QSFP28-100G-PSM4 only operates at fixed 100Gbps or 4x25G breakout mode, and there is no automatic speed downshift to 40G or 10G.

Q3: What kind of fiber connector cable should be matched with HYTOPTODEVICE compatible Huawei QSFP28-100G-PSM4 500m single-mode module?

A: HYTOPTODEVICE Huawei QSFP28-100G-PSM4 must be used with female MPO/MTP APC single-mode ribbon cable to guarantee stable 500m signal transmission.

Q4: Which MPO polarity cable is suitable for direct transceiver-to-transceiver links built with HYTOPTODEVICE Huawei 100G PSM4 optics?

A: Standard Type-B Key-Up to Key-Up crossover MPO-12 APC cable is required for point-to-point direct connections using HYTOPTODEVICE Huawei QSFP28-100G-PSM4.

Q5: Why is regular cleaning of MPO end faces essential for stable leaf-spine data center links deployed with HYTOPTODEVICE Huawei 100G PSM4?

A: Extremely critical. Each MPO connector contains multiple fiber cores; tiny dust particles will block an entire 25G lane and generate severe return loss on HYTOPTODEVICE Huawei QSFP28-100G-PSM4.

Q6: What breakout patch cord matches HYTOPTODEVICE Huawei QSFP28-100G-PSM4 to expand 4-channel 25G server uplinks?

A: MPO-APC female to 4x Duplex LC single-mode breakout patch cable works perfectly with HYTOPTODEVICE Huawei QSFP28-100G-PSM4 to realize 100G split transmission.

Q7: What are the core optical distinctions between HYTOPTODEVICE Huawei 100G PSM4 and 100G SR4 QSFP28 transceivers?

A: HYTOPTODEVICE Huawei PSM4 uses 1310nm OS2 single-mode fiber with a 500m transmission limit, while SR4 adopts 850nm OM3/OM4 multimode fiber only up to 100m; the two cannot be optically interconnected.

Q8: How does the power consumption of low-power HYTOPTODEVICE Huawei QSFP28-100G-PSM4 compare with CWDM4 and LR4 optical modules?

A: HYTOPTODEVICE Huawei QSFP28-100G-PSM4 has typical power consumption ≤2.5W and maximum 3.5W, which runs cooler and saves more power than CWDM4 and LR4 multiplexed transceivers.

Q9: What operating temperature ranges are offered for bulk wholesale HYTOPTODEVICE Huawei QSFP28-100G-PSM4 parallel transceivers?

A: Standard HYTOPTODEVICE commercial version supports 0°C to 70°C for indoor data centers, and customized industrial grade (-40°C ~ 85°C) is available for harsh special deployment environments.

Q10: What MPO polarity cable do I need for direct Huawei transceiver-to-transceiver PSM4 links?

A: A standard Type-B (Key-Up to Key-Up) crossover MPO-12 APC cable is required for direct connection.

Q11: How important is regular MPO end-face cleaning for consistent Huawei leaf-spine PSM4 links?

A: Extremely critical. An MPO connector has 8 or 12 exposed fiber ends; a single particle of dust can block an entire 25G lane or cause high optical return loss.

Q12: What fundamental optical difference exists between 100G PSM4 and 100G SR4 transceivers?

A: SR4 uses Multimode Fiber (OM3/OM4, 850nm) up to 100m. PSM4 uses Single-Mode Fiber (OS2, 1310nm) up to 500m.

Q13: What temperature operating ranges are offered for HYTOPTODEVICE Huawei PSM4 modules?

A: Standard Commercial Temperature range is 0°C to 70°C (32°F to 158°F). Industrial grade (-40°C to 85°C) is available for special applications.

Q14: Why choose HYTOPTODEVICE PSM4 over LR4 for under-500m Huawei rack interconnections?

A: This PSM4 module features simplified internal architecture, lower unit pricing and ultra-low power draw, making it the most economical high-density solution for QFX leaf-spine intra-fabric links.

Q15: In which network projects will CWDM4 duplex optics beat mass MPO PSM4 on total deployment cost?

A: CWDM4 delivers lower overall expenses for cross-building long-distance links or small fiber-count projects; expensive MPO ribbon cables erase PSM4 module cost advantages.
