Description

Cisco C53 DWDM‑SFP‑3504‑80 Compatible 1.25G DWDM Transceiver Module | 1000BASE‑DWDM 1535.04nm 80km Bulk Wholesale

Product Overview

HYTOPTODEVICE C53 DWDM SFP is drop‑in replacement for Cisco DWDM‑SFP‑3504‑80, built on ITU‑T 100GHz grid at 1535.04nm, delivering stable error‑free 80km transmission over G.652.D single‑mode fiber. This cost‑effective cisco compatible dwdm sfp 80km is widely chosen by system integrators and service providers for metro DWDM backbone build‑out and existing fiber capacity expansion tender projects.

It adopts TEC‑cooled DFB laser for tight wavelength locking and low inter‑channel crosstalk under dense wavelength multiplexing. Max power consumption＜2W. Factory pre‑tuned EEPROM supports hot‑swap plug‑play without unrecognized transceiver alarms. Built‑in SFF‑8472 DOM allows real‑time optical parameter reading for on‑site debugging and daily network maintenance. We support pre‑ship sample testing and large‑volume bulk order for DWDM network upgrade.

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: Can I re‑program the transceiver if I change my network equipment later?

A: HYTOPTODEVICE supports secondary EEPROM re‑programming for this C53 DWDM‑SFP‑3504‑80 compatible module. If you migrate to different host hardware after purchase, our technical team can re‑write the identification profile to match your new gear, keeping the transceiver fully functional for your updated network setup.

Q2: How do I select the right optical connector type (UPC vs. APC)?

A: For this 100GHz 1.25G DWDM SFP working at 1535.04nm 80km, UPC‑polished LC‑PC is the factory default and recommended for standard DWDM MUX/DEMUX links. APC connectors deliver better return‑loss performance for passive optical networks, but please consult HYTOPTODEVICE support before switching to avoid unexpected channel crosstalk within dense DWDM systems.

Q3: Is guest or parameter configuration required before deployment?

A: Our Cisco‑compatible C53 DWDM transceiver comes pre‑calibrated and pre‑profiled out‑of‑box. No extra guest mode activation or manual parameter tuning is necessary for most Cisco‑family hosts. Just complete physical insertion and hot‑swap, and the module will work immediately in qualified network environments.

Q4: How do I verify signal quality after installation?

A: After plugging in this DWDM SFP, you can validate link performance in two practical ways. Read real‑time DDM metrics from your switch CLI or web interface to check Tx/Rx power levels. HYTOPTODEVICE also suggests running link‑level BER testing to confirm stable 80km transmission performance before putting the circuit into formal service.

Q5: Can high Tx power damage the transmitter if left disconnected?

A: This TEC‑cooled C53 DWDM SFP features built‑in laser safety protection. Under normal operating mode, disconnecting the fiber cable will not burn out the transmitter chip. Still, HYTOPTODEVICE recommends installing dust caps on vacant LC ports to block contaminants and avoid unnecessary laser exposure risks.

Q6: Are your products resistant to dust, humidity, and static electricity (ESD)?

A: All HYTOPTODEVICE DWDM transceivers including this C53 model adopt industrial‑grade anti‑static design. Each unit goes through humidity and ESD stress testing during production. Proper anti‑static operating procedures are still required during on‑site handling, and dust caps should stay fitted when optical interfaces are unused.

Q7: Can DDM warn me before a link actually fails?

A: Yes, the integrated DDM function of our C53 DWDM SFP provides early‑stage threshold alerts. When optical power, temperature or supply voltage approaches critical limits, host equipment can trigger warning notifications ahead of total link breakdown. It helps network operators carry out preventive maintenance instead of waiting for complete service outage.

Q8: How accurate are the real‑time DDM optical power readings?

A: For this 1.25G 100GHz DWDM transceiver, factory calibration keeps DDM optical power measurement within the industry‑accepted accuracy tolerance. Readings serve as reliable reference for daily network monitoring. For absolute‑precision lab measurement, external optical test instruments from HYTOPTODEVICE test suite are advised.

Q9: Does DDM require special software or extra licenses?

A: DDM / DOM function of our C53 compatible DWDM SFP complies with SFF‑8472 standard. No proprietary software and no paid license is needed. You can fetch all diagnostic data directly through native CLI commands or built‑in web management of your existing network switches and routers.

Q10: What if an item arrives dead‑on‑arrival (DOA) or damaged?

A: HYTOPTODEVICE runs full optical performance testing for every DWDM module before shipment. In rare cases of DOA or transit‑caused damage, please provide receiving photos and test records. Our support team will quickly handle replacement solutions for your bulk or project orders.

Q11: What technical documentation accompanies each purchase?

A: When you place orders for our C53 Cisco‑compatible DWDM SFP, you will receive product datasheets covering wavelength specs, optical parameters and mechanical dimensions. For large‑volume project clients, HYTOPTODEVICE can additionally supply test reports and compliance certificates upon request.

Q12: Can your engineers assist with link budget calculations before purchase?

A: Absolutely. HYTOPTODEVICE technical engineers can help finish link budget evaluation for your 80km DWDM deployment. Share your fiber length, MUX/DEMUX insertion loss and amplifier layout information in advance, and we will give practical suggestions for your metro DWDM project planning.
