Description

CWDM-SFP10G-1570-40 Compatible Cisco 10G CWDM SFP Module 40km | 1570nm Long-Haul CWDM Optical Transceiver， Bulk Wholesale Procurement Available

Product Overview

HYTOPTODEVICE 1570nm 40km 10G CWDM SFP MODULE is a factory-calibrated, fully compatible replacement for the original Cisco CWDM-SFP10G-1570-40 optical module. Featuring a standard LC duplex interface and compliant with ITU-T G.694.2 upper-band wavelength specifications, this 10G CWDM SFP MODULE delivers stable 10.3125Gbps full-duplex transmission up to 40km over G.652 and G.655 single-mode fiber. As a key upper-band fill channel in the complete 1470–1610nm CWDM wavelength grid, the 1570nm wavelength features ultra-low crosstalk and high channel isolation, perfectly solving full-spectrum CWDM network vacancy problems. Equipped with real-time DDM digital monitoring and industrial-grade EML laser chips, the module maintains ≤1W low power consumption, providing reliable upper-band channel expansion solutions for carrier metro networks and large enterprise long-distance backbone systems.

Key Technical Specifications

This 1570nm upper-band 10G CWDM SFP MODULE strictly follows SFF-8431, SFF-8472 and IEEE 802.3ae international industry standards. Each finished 10G CWDM SFP MODULE undergoes exclusive 1570nm wavelength precision calibration, laser power stability testing, receiving sensitivity verification, link budget margin detection and wide-temperature aging tests. Strict multi-stage quality screening ensures consistent photoelectric performance, making it a reliable upper-band supplement for full-scale CWDM multiplexing networking projects.

Usage Guidelines & Laser Safety

This 1570nm upper-band 10G CWDM SFP MODULE is designed for 40km long-distance CWDM multiplexing channel supplementation. Avoid direct eye observation of powered optical ports to prevent laser radiation damage. ESD anti-static protection is required during installation and maintenance to protect internal precision laser and receiver chips. Ultra-short distance direct connection without optical attenuators will cause receiver saturation and permanent module damage. Keep LC dust caps installed when the 10G CWDM SFP MODULE is idle to avoid dust contamination and extra link loss, ensuring stable upper-band channel operation.

FAQ

Q1: Can HYTOPTODEVICE 1570nm 40km 10G CWDM SFP MODULE work normally on HP and Aruba switches?

A1: Standard 1570nm 10G CWDM SFP MODULE cannot run on HP/Aruba switches due to strict vendor code locking. Only HYTOPTODEVICE modules pre-programmed with dedicated HP/Aruba compatible firmware can avoid port shutdown and achieve stable plug-and-play operation.

Q2: Is the 1570nm 10G CWDM SFP MODULE backward compatible with legacy 1G SFP switch ports?

A2: No. HYTOPTODEVICE 1570nm 40km 10G CWDM SFP MODULE is designed exclusively for native 10G SFP+ slots. It does not support automatic down-negotiation to 1G speed, even in mixed-rate switch environments without dedicated firmware adaptation.

Q3: Do common network switches support 1570nm upper-band CWDM wavelength for 10G transmission?

A3: Standard switches are wavelength-agnostic for 10G CWDM SFP MODULE deployment. They only identify SFP+ form factor and 10G rate, while 1570nm upper-band wavelength multiplexing and identification are completely processed by passive CWDM MUX/DEMUX devices.

Q4: Does the 40km marking on the 1570nm 10G CWDM SFP MODULE guarantee full 40km fiber transmission availability?

A4: No. The 40km parameter is a theoretical industry standard value. This 10G CWDM SFP MODULE has an actual 14–16dB effective link budget. Real-world fiber attenuation, splice loss and panel loss must be calculated to verify valid transmission distance.

Q5: How much insertion loss does CWDM MUX/DEMUX add to 1570nm 40km 10G CWDM SFP MODULE links?

A5: Standard 8-channel CWDM MUX/DEMUX introduces 1.5–3.0dB single-side insertion loss for 1570nm upper-band links. A complete round-trip link produces 3–6dB total loss, which reduces the maximum achievable transmission distance of the module.

Q6: Is an optical attenuator required for short-distance deployment of 1570nm 10G CWDM SFP MODULE?

A6: Yes. Short-span deployment under 5km requires an optical attenuator. The 40km-grade receiver of HYTOPTODEVICE 1570nm 10G CWDM SFP MODULE has a low overload threshold. Excess transmit power will blind the receiver and cause permanent hardware damage; 5dB or 10dB fixed attenuators are recommended.

Q7: Can I use a single 1570nm wavelength for bidirectional simplex fiber transmission with standard 10G CWDM SFP MODULE?

A7: No. HYTOPTODEVICE 1570nm 10G CWDM SFP MODULE is a duplex dual-fiber module. Single-fiber bidirectional transmission requires specialized BiDi CWDM modules or dual-wavelength single-fiber MUX configurations instead of standard duplex modules.

Q8: How to visually distinguish the 1570nm upper-band 10G CWDM SFP MODULE without device testing?

A8: HYTOPTODEVICE adopts exclusive color-coded pull latches and clear wavelength labeling for every 10G CWDM SFP MODULE. Users can quickly identify the 1570nm upper-band specification through standardized appearance markings without plugging into network devices.

Q9: What is the chromatic dispersion penalty for 1570nm 10G CWDM SFP MODULE during 40km transmission?

A9: The 1570nm upper-band wavelength produces a 1–2dB chromatic dispersion penalty at 40km transmission. This loss must be included in the overall link budget calculation to guarantee error-free long-haul CWDM network operation.

Q10: Can standard optical power meters accurately test 1570nm CWDM links with 10G CWDM SFP MODULE?

A10: No. Ordinary broadband power meters cannot capture independent 1570nm CWDM wavelength signals. Accurate link testing for HYTOPTODEVICE 10G CWDM SFP MODULE requires a professional CWDM-selective power meter tuned specifically to 1570nm.
