4. FAQ Section

• Q1: What is 100G PSM4 technology?A1: 100G PSM4 (Parallel Single Mode 4-lane) is an optical transceiver standard that uses four parallel single-mode fiber lanes, each transmitting data at 25Gbps, to achieve an aggregate data rate of 100Gbps. It typically uses an MPO-12 connector and is designed for reaches up to 10km.
• Q2: What type of fiber cable is required for this QSFP28 PSM4 transceiver?A2: This transceiver requires a single-mode fiber (SMF) optic cable with an MPO-12 APC (Angled Physical Contact) connector. Specifically, it uses 8 out of the 12 fibers in the MPO connector (4 for transmit, 4 for receive).
• Q3: Is this transceiver compatible with my Cisco/Juniper/Arista switch?A3: Our QSFP28 100G PSM4 transceivers are MSA (Multi-Source Agreement) compliant and can be programmed to be compatible with a wide range of networking equipment from major vendors like Cisco, Juniper, Arista, Dell, and more. Please specify the required switch model or brand when placing your order or requesting a quote.
• Q4: What is the difference between 100G PSM4 and 100G LR4?A4: Both are 100G QSFP28 transceivers for 10km reach over SMF. However, 100G PSM4 uses four parallel fiber lanes (requiring an MPO connector and 8 fibers). 100G LR4 uses WDM (Wavelength Division Multiplexing) to transmit four different wavelengths over a single pair of fibers (requiring a duplex LC connector). PSM4 is often more cost-effective for certain applications, especially where MPO cabling infrastructure is already present or preferred.
• Q5: Does this module support Digital Diagnostics Monitoring (DDM/DOM)?A5: Yes, this QSFP28 100G PSM4 transceiver supports DDM/DOM functions according to SFF-8636. This allows for real-time monitoring of parameters such as temperature, supply voltage, laser bias current, transmit optical power, and receive optical power.
• Q6: What is the maximum power consumption of this transceiver?A6: The maximum power consumption is less than 3.5 Watts, making it an energy-efficient choice for 100G deployments.

5. Installation Steps

Installing your QSFP28 100G PSM4 Transceiver:

1. Safety First: Always wear an ESD (Electrostatic Discharge) wrist strap or take other anti-static precautions to prevent damage to the transceiver and host device.
2. Remove Dust Plugs: Remove the protective dust plug from the transceiver’s optical port and the port on the host device. Also, remove the dust cap from the MPO fiber optic cable connector.
3. Inspect Optical Interface: Before connecting the fiber, inspect the MPO connector end-face on the cable for any dust or contamination. Clean if necessary using an appropriate MPO cleaner.
4. Insert Transceiver: Align the QSFP28 transceiver with the port in your switch or networking device. Slide the transceiver gently into the port until it clicks into place. Do not force it. The module is keyed to ensure correct orientation.
5. Secure Transceiver (if applicable): Some QSFP28 ports have a bail latch or pull tab. Ensure it is properly engaged if present.
6. Connect Fiber Optic Cable: Connect the MPO-12 APC single-mode fiber optic cable to the transceiver’s MPO receptacle. Ensure proper alignment and that the connector is fully seated.
7. Verify Operation: After installation, check the host device’s status indicators or management interface to confirm that the link is active and operating correctly. Use DDM/DOM features to check optical parameters if needed.

Removing the Transceiver:

1. Disconnect Fiber Cable: Carefully disconnect the MPO fiber optic cable from the transceiver. Immediately place dust caps on both the transceiver port and the fiber connector.
2. Release Latch: Disengage the transceiver’s latching mechanism. This might be a pull tab or a bail clasp.
3. Remove Transceiver: Gently pull the transceiver straight out from the port.
4. Protect Transceiver: Place the transceiver in an ESD-safe bag for storage or transport.
