6. FAQ Section:

Address common questions to reduce support inquiries and build confidence.

• Q1: What is PSM4 technology in a QSFP28 transceiver?
  • A1: PSM4 (Parallel Single Mode 4-lane) technology uses four parallel single-mode fiber lanes, each transmitting data at 25Gbps25 \text{Gbps}25Gbps, to achieve an aggregate data rate of 100Gbps100 \text{Gbps}100Gbps. It’s designed for short-to-medium reach applications, typically up to 2km2\text{km}2km or 10km10\text{km}10km depending on the specific PSM4 variant, using an MTP/MPO connector.
• Q2: What type of fiber optic cable is required for this 100G PSM4 transceiver?
  • A2: This transceiver requires a Single-Mode Fiber (SMF) patch cable with an MTP/MPO-12 APC (Angled Physical Contact) connector. It utilizes 8 out of the 12 fibers (4 transmit, 4 receive).
• Q3: What is the difference between QSFP28 PSM4 and QSFP28 CWDM4/LR4?
  • A3: PSM4 uses parallel fibers and separate lasers for each lane, making it cost-effective for shorter distances. CWDM4 and LR4 use Wavelength Division Multiplexing (WDM) to combine multiple wavelengths onto a single pair of fibers (duplex LC connector), generally for longer reaches (CWDM4 up to 2km2\text{km}2km, LR4 up to 10km10\text{km}10km). PSM4 uses MTP/MPO connectors, while CWDM4/LR4 use LC connectors.
• Q4: Is this transceiver hot-pluggable?
  • A4: Yes, this QSFP28 module is hot-pluggable, allowing you to install or remove it from a compatible port without powering down the network device.
• Q5: What does DDM/DOM mean for this transceiver?
  • A5: DDM (Digital Diagnostics Monitoring) or DOM (Digital Optical Monitoring) allows the host system to monitor real-time parameters of the transceiver, such as optical transmit power, optical receive power, laser bias current, temperature, and supply voltage. This helps in diagnosing and predicting potential issues.
• Q6: How do I ensure compatibility with my networking equipment (e.g., Cisco, Juniper, Arista)?
  • A6: Our transceivers are built to MSA (Multi-Source Agreement) standards for broad compatibility. For specific vendor compatibility, please provide us with the model of your switch or router, and we can confirm or ensure the transceiver is programmed accordingly. You can also check our online compatibility guide [link if available].

7. Installation Steps (Simple & Clear):

1. Safety First: Wear an ESD (Electrostatic Discharge) wrist strap to prevent damage to the transceiver and equipment.
2. Remove Dust Caps: Take off the protective dust cap from the QSFP28 transceiver’s optical port and the MTP/MPO fiber optic cable connector.
3. Insert Transceiver: Carefully slide the QSFP28 transceiver into an empty QSFP28 port on your switch, router, or NIC until it clicks into place.
4. Connect Fiber Cable: Connect the MTP/MPO-12 SMF patch cable to the transceiver’s optical interface. Ensure the connector is properly aligned and seated.
5. Verify Connection: Check the port status LEDs on your network device to confirm a successful link. You can also check the interface status via the device’s command-line interface (CLI) or management software.
