A:
No, the LS-SM552G-80I is a fixed 2.5Gbps rate optical transceiver designed specifically for 2.5G SFP / SFP+ ports or multi-rate ports manually configured for 2.5G operation. It does not support automatic rate fallback to 1000BASE-X 1.25G unless the host port explicitly supports manual rate forcing. By

A:
Yes, an optical attenuator is strongly recommended when bench testing this module over short fiber cables. Because the LS-SM552G-80I utilizes a high-gain APD (Avalanche Photodiode) receiver and a DFB transmitter outputting up to +3dBm, plugging it directly into a short patch cable without at least 10-15dB attenuation can saturate or permanently damage the sensitive APD receiver.

Upgraded our rural broadband backhaul from 1G to 2.5G using these 1550nm 80km SFPs. MSA compatibility allowed instant recognition on both MikroTik and Cisco edge routers. The APD receiver easily detects weak signals near -24dBm without packet loss during extreme winter temperatures down to -30°C. Truly impressive industrial grade transceivers. ;)

Perfect solution for inter-site enterprise networking where fiber distance exceeds 50km. The 1550nm DFB laser provides narrow spectral width, reducing chromatic dispersion penalty over long runs. DOM function accurately reads RX power and internal temperature. We swapped out expensive tier-1 brand modules and saw identical performance at a fraction of the cost.

The LS-SM552G-80I industrial transceivers work flawlessly over our 60km single-mode link with clean 2.5G throughput. However, the protective rubber dust caps were a bit loose in the ESD bag upon arrival. Modules were undamaged and installed fine, but dust protection in transit could be slightly snugger.

Outstanding 80km 2.5G optics for critical infrastructure links. We ran 24-hour RFC 2544 throughput tests on a 70km single-mode fiber spool. Zero frame loss and jitter remained sub-millisecond. DDM readings match our high-end optical power meter within 0.3dB. Best industrial grade SFP on the market for harsh environments.
