CWDM-SFP10G-1550-40 Compatible Cisco 10G CWDM SFP Transceiver 40km | 1550nm Long-Haul CWDM Optical Module， Bulk Wholesale Procurement Available

Product Overview
HYTOPTODEVICE 1550nm 40km 10G CWDM SFP Transceiver is a fully tested, plug-and-play replacement for the original Cisco CWDM-SFP10G-1550-40 module. Equipped with standard LC duplex interface, it delivers stable 10.3125Gbps full-duplex transmission up to 40km on G.652 and G.655 single-mode fiber. As the core premium-band wavelength in the ITU-T 1470–1610nm CWDM spectrum, this 10G CWDM SFP Transceiver features ultra-low signal attenuation and strong anti-interference capability, making it the preferred solution for long-haul metro CWDM multiplexing and enterprise core backbone networking. Built with high-performance optical chips and supporting real-time DDM digital monitoring, the module achieves ≤1W ultra-low power consumption, ensuring long-term stable and low-energy operation for premium-grade CWDM network projects.

Usage Guidelines & Laser Safety

This 1550nm premium-band 10G CWDM SFP Transceiver is designed for 40km long-haul CWDM multiplexing transmission. Avoid direct eye contact with powered optical ports to prevent laser damage. ESD anti-static protection is mandatory during installation and maintenance to protect internal precision optical chips. Short-distance direct connection without 10–15dB optical attenuators will cause APD receiver saturation and permanent module damage. Keep LC port dust caps covered when idle to prevent dust contamination and extra link loss, ensuring stable long-haul transmission performance of the 10G CWDM SFP Transceiver.

FAQ

Q1: Can HYTOPTODEVICE 1550nm 40km 10G CWDM SFP Transceiver work normally on HP and Aruba network switches?

A1: No, generic 1550nm 10G CWDM SFP Transceiver cannot run on HP/Aruba switches. HP and Aruba devices adopt strict vendor coding locking mechanisms. Only HYTOPTODEVICE modules pre-programmed with exclusive HP/Aruba compatible firmware can avoid port shutdown and achieve stable plug-and-play operation on these switch platforms.

Q2: Is HYTOPTODEVICE 1550nm 10G CWDM SFP Transceiver backward compatible with traditional 1G SFP switch slots?

A2: No. This 40km 10G CWDM SFP Transceiver is designed for native 10G SFP+ slots. It does not support automatic down-negotiation to 1G rate, unless the switch features dual-rate 1G/10G ports and matches customized transceiver firmware, which is not applicable for standard deployment scenarios.

Q3: How to confirm ordinary switch ports support 1550nm CWDM wavelength transmission for 10G networking?

A3: Standard network switches are wavelength-agnostic for HYTOPTODEVICE 1550nm 10G CWDM SFP Transceiver deployment. Switches only identify SFP+ form factor and 10G data rate, while 1550nm wavelength identification and signal multiplexing are fully undertaken by professional CWDM MUX/DEMUX passive devices.

Q4: Does the 40km mark on HYTOPTODEVICE 1550nm 10G CWDM SFP Transceiver guarantee full-distance fiber transmission availability?

A4: No. The 40km parameter is a standard industry theoretical value based on average fiber loss. This 10G CWDM SFP Transceiver features a 14–16dB actual optical link budget. Users must calculate real attenuation from fiber lines, splicing points and patch panels to confirm effective transmission distance.

Q5: How much insertion loss does CWDM MUX/DEMUX bring to 1550nm 40km 10G CWDM SFP Transceiver links?

A5: Standard 8-channel CWDM MUX/DEMUX introduces 1.5–3.0dB single-side insertion loss for 1550nm long-haul links. A complete round-trip link will generate 3–6dB total loss, which needs to be deducted from the module’s total link budget and will reduce the maximum supportable transmission distance.

Q6: Is an optical attenuator required for short-distance deployment of HYTOPTODEVICE 1550nm 40km 10G CWDM SFP Transceiver (such as 2km fiber links)?

A6: Yes, an attenuator is mandatory for short-span deployment. The 40km-grade receiver of this 1550nm 10G CWDM SFP Transceiver has an overload input power of -0.5~0.5dBm. Excess transmit power in ultra-short links will cause receiver blinding and permanent hardware damage; a 5dB or 10dB fixed optical attenuator is recommended.

Q7: Can I use identical 1550nm wavelengths for single-fiber bidirectional transmission with standard 40km 10G CWDM SFP Transceiver?

A7: No. HYTOPTODEVICE 1550nm 40km 10G CWDM SFP Transceiver is a standard duplex dual-fiber module, with independent transmitting and receiving fibers using the same wavelength. Single-fiber bidirectional scenarios require dedicated BiDi CWDM modules or single-fiber MUX devices with dual-wavelength matching.

Q8: How to quickly identify 1550nm wavelength specification of HYTOPTODEVICE 10G CWDM SFP Transceiver without equipment testing?

A8: HYTOPTODEVICE adopts standardized color-coded pull latches and clear external label marking for all CWDM modules. Users can directly distinguish the 1550nm premium-band wavelength through exclusive color identification and printed wavelength parameters on the module surface without plugging in devices.

Q9: What is the chromatic dispersion penalty for HYTOPTODEVICE 1550nm 10G CWDM SFP Transceiver at 40km transmission?

A9: For 40km long-haul transmission of this 1550nm 10G CWDM SFP Transceiver, the typical chromatic dispersion penalty ranges from 1–2dB. This loss factor must be fully included in the overall optical link budget calculation to ensure error-free stable long-distance transmission.

Q10: Can standard broadband optical power meters test 1550nm CWDM link performance of 10G transceivers accurately?

A10: No. Ordinary optical power meters are calibrated for 1310nm/1550nm broadband signals and cannot identify independent CWDM wavelength signals. Accurate detection for HYTOPTODEVICE 1550nm 10G CWDM SFP Transceiver links requires a professional CWDM selective power meter tuned to 1550nm.
