What do optical modules recycle for?

Q3 2026 reference prices: reusable 400G QSFP-DD modules CNY 150-500 each and faulty teardown units CNY 60-150; 800G OSFP teardown units CNY 120-300; harvested PAM4 DSPs (Marvell IN200/IN2012) CNY 40-120 and IN300 CNY 80-200; TIA/driver ICs CNY 3-10; VCSEL lasers (850nm) CNY 5-15; EML/CW lasers (1310nm) CNY 20-80.

Which optical modules are worth the most?

High-spec, high-grade, fully functional reusable modules command the most: single-mode schemes (DR8/FR4/LR4) carry EML/CW lasers with chip-level residual value above multi-mode SR8 (850nm VCSEL). 400G/800G modules with original labels and traceable batches reach hundreds of CNY per unit. In teardown parts, PAM4 DSPs and EML/CW lasers are the most valuable, while gold-plated module PCB fingers can be routed into precious-metal recovery.

What should you watch when recycling optical modules?

Four points: read the label to determine speed and reach (SR8/DR8/FR4/LR4), which decides the laser type inside; verify the DSP marking (Marvell IN200/IN300) and grade it separately; check the laser wavelength and burn state — a blackened emission facet means scrap; and run plug-and-play/optical-power functional tests to split reusable modules from teardown material, a 50%+ price gap. Optical devices are sensitive to ESD and humidity — store anti-static and moisture-protected, and verify brand markings for export compliance.

Optical Transceiver Chip Recycling: Residual Value of DSP, TIA & Laser Chips in the 800G/400G Data Center Module Retirement Wave

The AI Compute Race Is Minting Money for Recyclers Too

A single 400G QSFP-DD optical module sells new for hundreds to over a thousand RMB; crack it open and you find one PAM4 DSP, eight TIA/driver channels and four to eight lasers — every 10,000 GPU servers in an AI data center correspond to hundreds of thousands of optical modules, and the average module refresh cycle in data centers is only about three years. With 800G scaling in 2025 and 1.6T sampling in 2026, the first wave of mass-deployed 400G modules has entered its retirement and refurbishment window, turning optical module chip recycling from a "scrap-side business" into a dedicated, scalable stream. A faulty 400G module's chip and component value packages at CNY 60-150, and a reusable refurbishable unit reaches CNY 500 — by unit value density, optical modules are among the highest-value categories in today's e-waste, and most recyclers have not noticed yet.

Why Optical Modules Deserve Their Own Dedicated Grade

High unit value: a 400G QSFP-DD module carries hundreds of RMB in BOM; a single harvested PAM4 DSP sells for CNY 40-120, and whole reusable units CNY 150-500
Strong refurbishment & export demand: data centers and carriers across Southeast Asia, the Middle East and Latin America buy used optical modules; laser/DSP replacement and re-labeling refurbishment is a mature business
Laser & DSP scarcity: EML/CW lasers (1310nm) and Marvell IN200/IN300 PAM4 DSPs are chronically short in repair and design-house channels
Multiple added values: thick gold-plated PCB fingers, optical adapter ferrules and companion power-management ICs each price separately

The optical module problem is never "no demand" — it's "no grading." Whole-unit, DSP, laser and gold finger value stack four layers deep; blending them into generic scrap gives all of it away.

Optical Transceiver Chip Recycling Price Reference

Current reference prices for mainstream optical modules and photonic chips (Reference Price (CNY), Q3 2026):

Category	Representative models / brands	Reference Price (CNY)
400G QSFP-DD, whole (reusable)	InnoLight, Eoptolink, Accelink	150-500/unit
400G, whole (faulty / teardown)	InnoLight, Eoptolink, Accelink	60-150/unit
800G OSFP, whole (faulty / teardown)	InnoLight, Coherent	120-300/unit
Harvested PAM4 DSP (400G)	Marvell (formerly Inphi) IN200/IN2012	40-120/chip
Harvested PAM4 DSP (800G)	Marvell IN300	80-200/chip
Harvested TIA / driver IC	Macom, Semtech GN2559, domestic suppliers	3-10/chip
VCSEL laser (850nm multimode)	Coherent, Lumentum	5-15/chip
EML / CW laser (1310nm single-mode)	Coherent, Yuanjie Semiconductor	20-80/chip

Note: These are Q3 2026 reference ranges. Whole-module prices move with brand, reach spec (SR8/DR8/FR4/LR4) and condition; modules with original labels and full function command the most. Lasers are valued by burn state — a blackened emission facet is scrap.

Identification & Grading: Four Moves That Set the Quote

Read the label: the module label states speed and reach — SR8 uses 850nm VCSELs, DR8/FR4 use silicon photonics + CW lasers, LR4 uses EML; the spec decides the laser inside and the whole-unit tier
Verify the DSP: Marvell IN200/IN2012 (400G) and IN300 (800G) are the mainstream PAM4 DSPs — check the marking and grade separately, inspecting pin oxidation and ball condition
Check the laser: wavelength decides value — EML/CW (1310nm) prices 3-8x above VCSEL (850nm); lasers are burn-sensitive, and a blackened facet is scrap
Test function: plug-and-play recognition and optical-power tests split "reusable" from "teardown," a 50%+ price gap — test reports shipped with the lot command clear premiums

Mixing optical modules into generic e-scrap by weight hands your DSP and laser value to the refurbishers — graded properly, even a faulty module sells for double.

Who Buys Teardown Optical Modules & Chips?

Optical module refurbishers: buy faulty whole units, replace lasers/DSPs, re-label and resell, mainly exporting to Southeast Asia, Latin America and the Middle East
Data center operators & spares traders: steady demand for legacy-speed spares and same-model replacements, growing in step with AI compute buildouts
Photonic design houses & repair channels: harvest EML/CW lasers and DSPs for repair spares — chronically short, steady volume
Precious-metal lines: thick gold-plated module PCB fingers share the same recovery line as PCBA gold fingers

Advice for Recyclers

Whole units first: reusable modules are worth far more than teardown — functionally test before deciding to resell whole or strip chips
Grade lasers separately: sort by wavelength (850nm VCSEL / 1310nm EML/CW) and never mix with ordinary semiconductors
Keep ESD & moisture discipline: optical devices are static- and humidity-sensitive — anti-static, moisture-barrier storage and careful optical-port handling are basic practice
Retain labels & provenance: modules with original labels and traceable batches command clear premiums and ease export compliance
