Description

Cisco C40 DWDM‑SFP‑4532‑80 Compatible 1.25G DWDM SFP Transceiver Module | 1000BASE‑DWDM 1545.32nm 80km Bulk Wholesale

Product Overview

HYTOPTODEVICE C40 DWDM SFP provides full pin‑to‑pin compatibility for Cisco DWDM‑SFP‑4532‑80, built on the 100GHz ITU‑T C‑band grid at 1545.32nm central wavelength. It delivers robust error‑free transmission up to 80 km over G.652.D single‑mode fiber for dense wavelength‑division multiplexing infrastructures.

This transceiver adopts TEC‑cooled DFB laser to maintain strict wavelength tolerance and suppress inter‑channel crosstalk under dense channel layout. Power consumption remains below 2W under full load. Factory‑preloaded Cisco‑profile EEPROM eliminates "unrecognized transceiver" system alerts. Hot‑swap design plus complete SFF‑8472 DDM diagnostics streamline daily operation and fault troubleshooting for metro optical rings and geographically dispersed remote‑site backhaul links.

Usage Guidelines & Best Practices

Fiber & Connector: Use OS2 single-mode fiber with LC-UPC connectors only (LC-APC strictly prohibited). Match transceiver wavelength with your DWDM ITU channel.
Optical Attenuation (Crucial): Never direct-connect! Since Tx reaches up to +5 dBm, install a 10–15 dB inline attenuator at the Rx port during lab/short-link testing to keep input power below -3 dBm and prevent receiver burnout.
Architecture: Built with a Cooled DFB (TEC) transmitter and a PIN receiver (sensitivity ~ -24 dBm, 24 dB link budget).
Thermal Management: Operating temp: 0°C to 70°C. Proper airflow is essential for TEC wavelength locking to prevent link drops.
Handling: Supports hot-swapping via bail latch. Always clean LC fiber end-faces before connection.

FAQ

Q1: Will using third‑party compatible optics void the original manufacturer warranty of my network hardware?

A: In most global commercial markets, MSA‑compliant compatible transceivers will not void host‑device warranty. If your network hardware enforces strict OEM identification lock‑in, our no‑cost EEPROM tuning can suppress warning notifications and help you avoid warranty‑related conflicts. Reach out to us for region‑specific practical suggestions.

Q2: Can you customize module firmware for obsolete or industry‑specific networking equipment?

A: Our engineering team delivers custom EEPROM re‑flashing for specialized switches, end‑of‑life transport platforms and industrial communication hardware. Provide your exact device model details, and we will deliver targeted configuration within one working day with 24‑hour technical support access.

Q3: Does this C40 DWDM SFP meet Multi‑Source Agreement industry standards?

A: Every C40 unit strictly complies with SFP MSA mechanical, electrical and optical specifications, and supports full SFF‑8472 DDM diagnostic functions. Form factor, pin definition and optical performance all follow universal industry norms to guarantee reliable cross‑device interoperability.

Q4: What total link budget can this 1545.32nm DWDM SFP provide?

A: This module delivers 24dB total link budget calculated from its 0~+5dBm transmit power and ‑24dBm receiver sensitivity, supporting full 80km transmission over standard single‑mode fiber under typical attenuation conditions.

Q5: How does the unit sustain precise ITU‑T wavelength performance over thousands of working hours?

A: Built‑in TEC thermoelectric hardware dynamically regulates laser chip temperature together with factory‑grade wavelength calibration. This mechanism suppresses long‑term wavelength drift and maintains tight 100GHz channel spacing during non‑stop continuous operation.

Q6: Is there risk of complete link failure caused by accumulated insertion loss from DWDM MUX/DEMUX components?

A: The 24dB link margin absorbs regular insertion loss brought by multiplexer‑demultiplexer assemblies. When combined attenuation from fiber spans, splices and WDM parts exceeds budget limits, deploying EDFA amplifiers can recover signal power.

Q7: What is the minimum allowed fiber length without installing an optical attenuator?

A: The safe minimum unattenuated fiber distance for this 80km‑rated DWDM transceiver is 15 km. Any shorter connection must deploy a 10‑15 dBm fixed attenuator to prevent receiver optical saturation and permanent port damage.

Q8: Are internal surge‑protection circuits implemented inside the C40 optical module?

A: Integrated protective circuits safeguard laser and receiver chips against over‑voltage, over‑current and ESD spikes generated during hot‑swap insertion, enhancing hardware reliability within high‑density rack environments.

Q9: Why is active thermal control critical for wavelength‑locking performance in dense DWDM systems?

A: Laser output wavelength shifts significantly with temperature fluctuations. The embedded TEC adjusts laser operating temperature in real‑time to lock onto 1545.32nm ITU‑T channel and mitigate crosstalk between densely‑packed DWDM wavelengths.

Q10: What performance risks arise when the module runs above its maximum rated operating temperature?

A: Prolonged overheating triggers wavelength offset, increased bit‑error rates and erratic DDM readouts. Long‑term high‑temperature exposure accelerates laser aging. For hot‑location deployments, use rack cooling systems or select our industrial wide‑temperature variant.

Q11: What methods allow network administrators to fetch live DDM diagnostic metrics on managed switches?

A: Real‑time data including transmit power, receive power, module temperature and supply voltage can be retrieved via native switch CLI transceiver commands or web‑based management interfaces, no extra third‑party software installation required.

Q12: What protective measures are adopted in packaging to prevent fiber connector damage during worldwide shipment?

A: Each C40 transceiver is equipped with LC dust caps after full optical performance testing, then individually sealed inside anti‑static moisture‑proof bags with shock‑absorbing foam, protecting fiber end‑faces from scratches, dust and oil contamination throughout transit and handling.
