Product Overview

HYTOPTODEVICE Cisco DWDM-SFP10G-28.77  Compatible 10G DWDM SFP 80km Module is a carrier-grade, long-reach optical transceiver engineered for Cisco metro backbones, OTN transport, and enterprise long-span networks. Compliant with SFP+ MSA and ITU-T G.694.1 standards, this module operates on the 1528.77nm wavelength (C-Band, CH61) with 100GHz channel spacing, delivering stable 10.3125Gbps full-duplex data transmission up to 80km over SMF (G.652/G.655).

Pre-flashed with dedicated Cisco adaptive EEPROM firmware, it guarantees seamless, zero-alarm plug-and-play interoperability across all Cisco IOS and IOS-XE platforms. Featuring an industrial-grade EML laser, fast-response TEC cooling, and a high-gain APD receiver, the transceiver ensures precise wavelength locking, exceptional weak-signal sensitivity, and robust anti-interference performance. Each unit undergoes 100% wavelength calibration, thermal aging, and real-switch testing to provide a cost-effective, highly reliable solution for large-scale, high-density DWDM multiplexing projects.

Usage Guidelines & Laser Safety

• ESD Protection: Operators must wear a properly grounded ESD anti-static wrist strap during installation to prevent electrostatic discharge from damaging internal optical chips and circuits.
• Laser Safety Warning: NEVER look directly into the powered optical ports or fiber connectors. The invisible infrared laser radiation emitted can cause permanent and irreversible eye injury.
• Receiver Protection: For short-distance testing or links under 10km, an appropriate optical attenuator (typically 15–20dB) MUST be installed before connecting to the RX port. Failure to do so will cause APD receiver saturation, signal distortion, or permanent hardware damage.
• Optical Cleanliness: Thoroughly clean all fiber end-faces using professional cleaning tools before docking to minimize insertion loss and prevent contamination.
• Thermal Management: Ensure sufficient cabinet airflow and ventilation when deploying modules in high-density environments to prevent heat accumulation, which can cause wavelength drift or thermal shutdown.
• Proactive Maintenance: Regularly monitor Digital Optical Monitoring (DOM) data via the system CLI to proactively detect potential optical degradation.
Short-Distance Deployment Notice: > When deploying this Cisco-compatible 10G DWDM SFP 80km module over short distances, please refer to the attenuation reference table below to select the appropriate optical attenuator.

FAQ

Q1: Can this single-channel DWDM module be deployed within a BIDI bi-directional transmission architecture?

A1: This 1528.77nm C61 DWDM SFP module is engineered for unidirectional single-wavelength transmission and cannot support standalone BIDI operation. BIDI systems require paired transceivers with internal wavelength multiplexing structures for separated transmit and receive wavelengths. If clients need bidirectional long-distance transmission solutions, we can supply matched dedicated BIDI optical transceiver models separately.

Q2: Is professional technical support available if fiber communication links fail to establish normal connectivity after module installation?

A2: We provide full-lifecycle free technical support for all purchasers of our 1528.77nm C61 modules. Our professional engineering team offers remote troubleshooting guidance via email, video calls or online text to diagnose root causes of link failures, including compatibility conflicts, wiring errors and parameter mismatches. For complex on-site faults, we deliver detailed fault analysis reports and targeted resolution plans at zero extra cost.

Q3: Will installing this third-party optical module void the original hardware warranty of my network switch?

A3: Most mainstream network equipment manufacturers will not invalidate switch hardware warranties due to the use of fully MSA-compliant SFP transceivers. Our 1528.77nm C61 module strictly follows universal SFP MSA mechanical and electrical standards without damaging switch power circuits or signal channels. If clients encounter warranty disputes, our technical team can provide official specification documents to assist communication with equipment manufacturers.

Q4: Does this 10G DWDM SFP 80km Module fully comply with global RoHS and CE environmental compliance standards?

A4: The 1528.77nm C61 module strictly adheres to RoHS hazardous substance restriction regulations and has passed CE electromagnetic compatibility certification. All internal raw optical components, solder and plastic housings pass full compliance testing before mass production. Complete RoHS and CE certification documents can be provided to clients upon request for tender, import customs and project audit use.

A5: The 1528.77nm C61 module features reliable hot-swap compatibility and consistent hardware identification logic. While the switch executes firmware update tasks, the transceiver will temporarily pause data forwarding without unexpected crash or permanent hardware lockup. Once the upgrade procedure completes, the switch will automatically re-detect the module and restore full 10G transmission bandwidth without manual reinsertion.

Q6: Are the LC optical ports of this module fully protected against dust, fingerprint grease and surface abrasion during transit and on-site handling?

A6: Every HYTOPTODEVICE 1528.77nm C61 module is fitted with tight-fitting dedicated LC dust caps right after assembly. Matched with fully sealed anti-static shockproof individual packaging, the optical end faces are fully isolated from floating dust, oil stains and scratches during transportation, warehouse storage and field installation, retaining original factory optical transmission performance.

Q7: Is the module’s metal latching buckle robust enough to withstand frequent repeated plug-and-pull hot swap operations?

A7: The latching component of the 1528.77nm C61 module adopts reinforced high-toughness metal alloy with optimized structural design. Each unit undergoes thousands of cyclic insertion and extraction durability tests during factory inspection. The latch maintains firm locking force without loosening or fracture after long-term frequent hot swapping, preventing loose module seating inside switch slots.

Q8: Are there any hidden extra charges for specialized brand EEPROM coding or dedicated professional reprogramming equipment for this module?

A8: HYTOPTODEVICE provides 100% free custom brand EEPROM adaptation and firmware rewriting services for all bulk orders of the 1528.77nm C61 module. We never charge hidden service fees, equipment rental fees or calibration surcharges for compatibility programming work. Our in-house technical lab owns complete professional reprogramming tools, and all coding adjustment work is fully covered in the base product price.

Q9: What production lead time can bulk buyers expect for large-volume orders of this C61 DWDM module?

A9: HYTOPTODEVICE maintains stable sufficient raw material stock for the 1528.77nm C61 10G DWDM SFP 80km Module. Standard large batch orders without custom firmware coding requirements have a regular lead time of 7–10 working days. Orders needing dual-brand reprogramming or special customized packaging take roughly 12–15 working days, and priority production scheduling can be arranged for urgent project orders upon negotiation.

Q10: Do users need to deploy an external optical attenuator for short-distance fiber testing with this 80km long-reach DWDM module?

A10: The 1528.77nm C61 long-reach module delivers high transmit optical power designed for full 80km fiber spans. When testing on short fiber runs under 10km, excessive incoming light power may trigger receiver overload and sudden bit error spikes. We recommend matching a standard optical attenuator for short-distance lab testing to protect the internal APD receiver chip and ensure stable signal reception.
