Description

Extreme 100G-LR-QSFP10KM Compatible 100G QSFP28 Transceiver Module Single Lambda | LR 1310nm 10km SMF Duplex LC | HYTOPTODEVICE

Product Overview

This 100G QSFP28 transceiver serves as a field-proven replacement for Extreme 100G-LR-QSFP10KM, engineered to eliminate compatibility alarms and link instability on Extreme enterprise and data center hardware.

It adopts single-lambda PAM4 modulation paired with built-in KP4 FEC, delivering consistent 100G Ethernet traffic up to 10km over OS2 single-mode fiber. The onboard DSP converts four 25G electrical lanes into one unified 100G optical channel, maintaining clean signal performance across cross-floor, campus and inter-building long-haul links.

Designed to satisfy IEEE 802.3cd, QSFP28 MSA and 100G Lambda MSA standards, the module supports DDM/DOM real-time optical monitoring. Tuned EEPROM profiles enable hot-plug operation on Extreme equipment with minimal warning logs. It fits leaf-spine fabrics, long-distance aggregation trunks and phased bandwidth expansion via valid 400G PLR4 optical breakout.

Usage Guidelines & Best Practices

Fiber Requirement: Only OS2 single-mode fiber; OM3/OM4 multimode fiber cannot support 1310nm PAM4 transmission and will cause link failure.
FEC Configuration: Enable KP4 FEC on Extreme switch ports to maximize 10km link margin and sustain low BER stability.
Installation Specification: Hot-plug supported; keep LC end faces clean and maintain proper bend radius to avoid extra attenuation.
Distance Limit: Rated for 10km OS2 SMF; excessive splices, contaminated connectors or tight bends reduce effective transmission distance.
Operating Environment: Commercial temperature 0°C–70°C; keep ports dry and dust-free to extend QSFP28 transceiver service life.

Connectivity Solutions(Applications)

1. 100G to 100G for Switch-Switch Interconnection

This Extreme compatible QSFP28 transceiver extends core-to-aggregation trunk reach. It reuses existing OS2 single-mode fiber to deliver reliable 100G long-distance trunking without wholesale cable replacement

2.100G to 100G for Switch-NIC Connection

With rated 10km performance, the QSFP28 transceiver builds dependable long-range 100G uplinks between Extreme ToR switches and server NICs. Compact duplex LC cabling supports dense rack layouts, suited for HPC and AI clusters while reserving bandwidth headroom for future 400G upgrades.

3.100G to 400G Smooth Network Migration

This module works alongside 400G PLR4 ports to enable genuine optical 400G-to-4×100G breakout. Only PLR4 supplies four parallel 1310nm lanes over MPO-12 fiber to match 100GBASE-LR signaling. 400G FR4 and LR4 cannot perform this optical split, as they use CWDM multiplexing over duplex LC without independent parallel channels. Data centers can deploy new 400G spine hardware while preserving existing 100G leaf ports and cabling.

FAQ

Q1: What core differences separate modern 100G LR1 optics from conventional 100G LR4 transceivers?

A: HYTOPTODEVICE 100G LR1 is a next-gen single-lambda 100G solution that transmits full bandwidth over a standalone 1310nm PAM4 wavelength and duplex LC cabling. In contrast, traditional LR4 relies on four-wavelength multiplexing to split 100G traffic. The simplified single-channel structure of LR1 cuts hardware costs and cabling complexity, while the two generations remain optically incompatible for direct interconnection.

Q2: What official industry compliance standards govern modern 100G LR1 QSFP28 modules?

A: All HYTOPTODEVICE Huawei-compatible 100G LR1 transceivers strictly comply with IEEE 802.3cd Ethernet standards, universal QSFP28 MSA mechanical specifications and 100G Lambda MSA single-lambda protocols. This full standardization guarantees unified signal encoding, KP4 FEC performance, DDM monitoring and cross-platform adaptability for professional data center deployment.

Q3: What interface specification do current-generation 100G LR1 optical modules adopt?

A: HYTOPTODEVICE 100G LR1 QSFP28 modules utilize standard duplex LC/UPC physical connectors. This high-density, space-saving interface is optimized for 1310nm single-mode transmission, perfectly matching OS2 fiber cabling systems and meeting dense rack layout requirements for Huawei enterprise and data center networks.

Q4: Is identical network hardware branding required at both ends of a 100G LR1 fiber link?

A: Uniform switch brands are not mandatory for stable LR1 link operation. HYTOPTODEVICE standardized 100G LR1 modules deliver excellent cross-vendor interoperability. As long as both link ends deploy single-lambda 100G LR1 optics and synchronize KP4 FEC configurations, reliable long-distance transmission is achievable on multi-brand hybrid networks.

Q5: Do short-span fiber connections require optical attenuators to protect 100G LR1 transceiver receivers?

A: Short-distance links around 500m do not necessitate attenuators or cause receiver damage under normal deployment. HYTOPTODEVICE factory-calibrated 100G LR1 modules feature reasonable transmit power margins for short-range scenarios. Attenuator installation is only required if real-time DDM monitoring shows excessive incoming optical power beyond the receiver tolerance range.

Q6: Why do PAM4-based 100G LR1 links demand stricter fiber end-face cleanliness than older 100G NRZ optics?

A: PAM4 modulation delivers higher symbol density and spectral efficiency than traditional NRZ 100G transmission, resulting in far tighter signal error margins. Even microscopic dust, scratches or residual oil on LC end faces can distort optical waveforms, triggering hidden bit errors and intermittent packet loss. HYTOPTODEVICE emphasizes rigorous fiber cleaning for all PAM4 100G LR1 production links.

Q7: What is the typical power consumption level of commercial-grade 100G LR1 QSFP28 transceivers?

A: HYTOPTODEVICE industrial-calibrated 100G LR1 modules feature low power consumption, with steady operating power consistently maintained below 4.0W. The energy-efficient design effectively lowers overall switch heat generation, reduces data center PUE, and supports long-term stable 10km high-speed transmission.

Q8: Does full-density port deployment of 100G LR1 modules trigger thermal overheating risks for switches?

A: Single 100G LR1 modules generate minimal heat output, but fully populated high-density switch ports will accumulate concentrated thermal load. Poor chassis airflow, blocked ventilation ports or compact rack stacking will elevate module operating temperatures, gradually reducing optical link margin and shortening laser service life. Reasonable heat dissipation layout is essential for mass deployment.

Q9: How to select between EML and SiPh optical solutions for enterprise 100G LR1 networking builds?

A: HYTOPTODEVICE provides two mature technical routes for 100G LR1. Silicon Photonics (SiPh) modules excel in low power consumption and high-density scalability, ideal for modern compact leaf-spine data centers. EML laser solutions offer superior optical power budget and stronger attenuation tolerance, perfectly suited for legacy fiber environments with complex splicing and high loss.

Q10: What fast detection methods verify the operational quality of 100G LR1 modules during routine maintenance?

A: Field technicians can quickly assess module quality via multi-dimensional testing. Observe real-time DDM data for stable optical power and temperature fluctuations, enable KP4 FEC for full-rate bandwidth pressure testing, and monitor long-term BER indicators. All HYTOPTODEVICE modules complete factory aging and calibration, while unstable operating data in the field signifies faulty module performance.

Q11: Which 400G optical module supports legitimate optical breakout for 100G LR1 single-lambda links?

A: Only the 400G PLR4 module supports standard optical 4-to-100G breakout matching 100G LR1 single-lambda signaling. Unlike PLR4’s independent parallel 1310nm optical channels, 400G FR4 and LR4 adopt CWDM wavelength multiplexing architecture, which cannot achieve physical optical splitting for four separate 100G LR1 connections.
