Description

Cisco C34 DWDM‑SFP‑5012‑80 Compatible 1.25G DWDM SFP Transceiver Module | 1000BASE‑DWDM 1550.12nm 80km Bulk Wholesale

Product Overview

HYTOPTODEVICE C32 DWDM SFP is direct pin-to-pin replacement for Cisco DWDM‑SFP‑5172‑80, built on standard 100GHz ITU-T grid at 1551.72nm, supporting stable 80km transmission over G.652.D single-mode fiber. Equipped with industrial TEC cooled DFB laser and PIN receiver to cut channel crosstalk, power consumption under 2W. Preloaded Cisco EEPROM eliminates unsupported transceiver alerts, with hot-swap design and SFF-8472 compliant DDM diagnostics for metro rings and remote cell backhaul.

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 compatible transceivers void my host equipment’s warranty?
A: MSA-compliant compatible transceivers do not void equipment warranty under most regional trade regulations. If your vendor enforces OEM lock, our free custom EEPROM coding can remove recognition prompts to avoid maintenance disputes. Contact us for region-specific guidance.

Q2: Do you support custom coding for niche or specialized equipment?
A: We offer full EEPROM custom coding service for niche switches, industrial transport and legacy specialized hardware. Our engineering team delivers targeted technical solutions within one working day, and you can reach us 24/7 for support.

Q3: Are your products fully compliant with Multi-Source Agreements (MSA)?
A: All C34 DWDM SFP strictly follow SFP MSA mechanical, electrical and optical specs, together with full SFF-8472 DDM support. Form factor, pinout and signal performance fully meet official MSA standards.

Q4: What is the maximum optical link budget supported by this model?
A: This C34 DWDM module provides 24dB total link budget, calculated from 0~+5dBm transmit power and -24dBm receiver sensitivity, supporting up to 80km standard single-mode fiber under nominal loss.

Q5: How do WDM wavelengths stay accurate over extended usage?
A: Built-in TEC thermoelectric cooling continuously stabilizes laser chip temperature with factory calibration, suppressing wavelength drift and maintaining strict 100GHz ITU-T grid accuracy for long-term continuous operation.

Q6: Will insertion loss from DWDM/CWDM MUX/DEMUX cause link failure?
A: Normal insertion loss from multiplexers will not trigger link failure thanks to the 24dB link margin. If cumulative attenuation exceeds the budget, install EDFA amplifiers to compensate signal loss.

Q7: What is the minimum link distance required without using an attenuator?
A: The minimum safe unattenuated fiber distance for this 80km DWDM module is 15km. Shorter links must use a 10-15dBm fixed attenuator to prevent receiver overload and permanent damage.

Q8: Does the transceiver include built-in overcurrent or overvoltage protection?
A: Yes, integrated internal protection circuits guard against overvoltage, overcurrent and ESD surges during hot swap, effectively protecting laser and receiver chips from electrical damage.

Q9: How does thermal management affect wavelength locking in DWDM modules?
A: Laser wavelength shifts sharply with temperature changes. The embedded TEC dynamically regulates laser temperature to lock the 1550.12nm channel and eliminate inter-channel crosstalk.

Q10: What happens if a transceiver exceeds its maximum operating temperature?
A: Excessive heat leads to wavelength drift, higher bit error rate and abnormal DDM data. Sustained overheating shortens laser service life; use rack cooling or industrial wide-temperature modules for high-temperature environments.

Q11: How do I access DDM parameters on my network switch?
A: View real-time DDM metrics via standard switch CLI transceiver commands or web management GUI. All Tx power, Rx power, temperature and voltage data are exposed following SFF-8472 without extra software.

Q12: How do you prevent end-face contamination during shipping?
A: Every module is fitted with LC dust caps after optical testing, individually packed in anti-static moisture-proof bags with shock foam, avoiding fiber end-face scratches, dust and oil pollution in transit.
