Usage Guidelines & Laser Safety

This 1490nm max band cwdm sfp 10g transceiver is designed for 40km long-haul full-spectrum CWDM stacking and outdoor remote fiber transmission. Never look directly into powered optical ports to avoid irreversible laser eye damage. ESD anti-static gear must be worn during installation and maintenance to protect internal precision laser and receiver chips. Short-distance direct fiber connection without 10–15dB optical attenuators will cause APD receiver saturation and permanent hardware damage. Keep LC port dust caps covered when idle to prevent dust contamination and extra link loss, ensuring stable low-crosstalk operation of the 1610nm final CWDM channel.

For detailed operation instructions, please refer to the User Guide.

A1: Yes, our HYTOPTODEVICE 1490nm 40km Cisco CWDM 10G SFP+ Transceiver achieves native plug-and-play compatibility with all mainstream Cisco Catalyst, ISR and ASR series hardware. We finish full EEPROM matching testing before delivery to eliminate unrecognized module alarms and activate complete DDM monitoring function.

Q2: What fiber types and maximum transmission reach does HYTOPTODEVICE 1490nm Cisco CWDM 10G SFP+ Transceiver support?

A2: This mid-low band Cisco CWDM 10G SFP+ Transceiver delivers stable 40km transmission over G.652 and G.655 single-mode fiber via LC duplex connector, following ITU-T 1490nm standard CWDM wavelength specification for metro and campus CWDM multiplexing deployment.

Q3: What unique strengths does HYTOPTODEVICE 1490nm CWDM transceiver own compared with generic aftermarket CWDM modules?

A3: Our 1490nm Cisco CWDM 10G SFP+ Transceiver uses mature high-density optical chips with power consumption capped at ≤1W. Every unit passes full photoelectric inspection, supports reconfigurable EEPROM to fit multi-brand switches and cut global stock costs for system integrators.

Q4: Can HYTOPTODEVICE provide custom EEPROM coding for locked multi-brand network hardware?

A4: Yes, we launch professional custom EEPROM re-flash service for the 1490nm 40km Cisco CWDM 10G SFP+ Transceiver. Our technical team rewrites module vendor IDs and protocol parameters to adapt to Cisco, Juniper, Huawei and other locked-brand switches without extra hardware modification.

Q5: Which networking scenarios is HYTOPTODEVICE CWDM-SFP10G-1490-40 designed to serve?

A5: This mid-low band Cisco CWDM 10G SFP+ Transceiver targets medium-density multi-wavelength multiplexing, widely deployed in metropolitan access CWDM expansion, campus backbone interconnection, enterprise private lines and short-medium wireless CPRI backhaul links.

Q6: Does HYTOPTODEVICE 1490nm CWDM SFP+ Transceiver support hot-plug operation on live powered switch ports?

A6: Yes, our Cisco CWDM 10G SFP+ Transceiver complies with SFP+ MSA hot-swap industrial standards. Safe hot-plug replacement is available on live switch ports without interrupting the whole switch or other port services, simplifying on-site maintenance work.

Q7: What full wavelength range does HYTOPTODEVICE’s 40km 10G CWDM SFP+ Transceiver series cover?

A7: HYTOPTODEVICE’s full 40km Cisco CWDM 10G SFP+ Transceiver product line includes 8 complete ITU-T standard channels from 1470nm to 1610nm with fixed 20nm spacing, and this 1490nm mid-low wavelength fills core medium channels for mid-density CWDM system construction.
