Questions & Answers
What is the QSFP28-50G-BIDI-10km-SM-2 transceiver?
The QSFP28-50G-BIDI-10km-SM-2 is a Huawei 50G BiDi transceiver in a QSFP28 form factor, featuring LC connectors, dual wavelengths (1271 nm/1331 nm) and a maximum reach of 10 km over single-mode fiber.
Which applications support this Huawei BiDi transceiver?
This module is ideal for 50 GbE data center links, campus aggregation, metro access and enterprise backbones requiring high-density, cost-efficient single-fiber connectivity.
What are the key optical specifications?
Key optical specs include a 50 Gbps data rate; TX wavelength 1271 nm; RX wavelength 1331 nm; output power –4.5 dBm; receiver sensitivity –8.9 dBm; optical budget 4.2 dB.
What connector type does it use?
The QSFP28-50G-BIDI-10km-SM-2 uses a duplex LC connector compliant with TIA/EIA-604-10 standards for reliable single-mode fiber coupling.
What is the maximum transmission distance?
It supports transmissions up to 10 km over G.652 single-mode fiber assuming maximum fiber loss of 0.4 dB/km and standard splice/connector allowances.
What wavelengths does this transceiver employ?
This BiDi module uses 1271 nm for transmission (TX) and 1331 nm for reception (RX), enabling bidirectional communication over a single fiber strand.
Which network standards are supported?
The transceiver complies with IEEE 802.3cd 50 GbE, OIF CEI-28G-VSR, SFF-8636, RoHS and FDA CFR Title 21 requirements for optical modules.
How does BiDi technology benefit fiber deployment?
BiDi technology halves the fiber count by using two wavelengths on one strand, reducing cabling complexity, rack space and installation costs in high-density environments.
Is the QSFP28-50G-BIDI-10km-SM-2 hot-swappable?
Yes, the module is hot-pluggable, allowing insertion and removal from compatible QSFP28 ports without powering down the system.
How do I install this QSFP28 transceiver?
Align the module’s latch with the switch port cage, slide it in until it clicks, then verify the link LED or management interface shows an active connection.
What is the typical power consumption?
The transceiver consumes up to 3.5 W during operation, meeting standard QSFP28 thermal and power specifications.
Does this module comply with industry standards?
Yes, it meets IEEE 802.3cd, SFF-8636, RoHS, FDA CFR Title 21 and CE safety directives to ensure regulatory compliance.
What is the operating temperature range?
Operating temperatures range from 0 °C to 70 °C (32 °F to 158 °F); storage range is –40 °C to 85 °C (–40 °F to 185 °F).
Can it be used in DWDM networks?
No. This transceiver is designed for BiDi WDM applications on single-mode fiber, not for DWDM wavelength grids in multiplexed systems.
How can I ensure compatibility with my network switches?
Confirm your switch supports QSFP28 50 GbE BiDi optics, check firmware release notes for BiDi support, and verify vendor interoperability matrices.
What is the expected lifetime and reliability?
The module offers an MTBF exceeding 1 million hours and includes a one-year manufacturer warranty covering defects under normal operating conditions.
