Is the LINK-PP LS-MM8525E-S1C compatible with Cisco, Arista, and Dell switches out of the box, and does it support dual-rate 10G/25G auto-negotiation?

Yes, the LS-MM8525E-S1C SFP28 optical transceiver features custom EEPROM coding designed for seamless plug-and-play compatibility with major OEM brands including Cisco, Arista, Dell, Juniper, and Mellanox. It fully supports dual-rate 10Gbps and 25Gbps operations over 850nm MMF, automatically adapting to your switch port configuration without triggering third-party optic warnings.

What is the operating temperature range and power consumption for high-density rack deployments?

The LS-MM8525E-S1C operates within a standard commercial temperature range of 0°C to 70°C (32°F to 158°F) with low power consumption (typically < 1W per unit). Its low thermal dissipation makes it ideal for high-density top-of-rack (ToR) switch deployments, enterprise server uplinks, and data center leaf-spine architectures.

What is the maximum transmission distance over OM3 and OM4 multimode fiber, and does this module include digital optical monitoring (DOM)?

The LS-MM8525E-S1C utilizes an 850nm VCSEL transmitter and PIN receiver over duplex LC MMF cable, supporting reach up to 70 meters on OM3 MMF and up to 100 meters on OM4 MMF. It includes built-in DOM/DDM (Digital Diagnostics Monitoring) capability compliant with SFF-8472, allowing network engineers to monitor real-time parameters such as optical output power, optical receive power, temperature, laser bias current, and supply voltage via CLI or SNMP.

Replaced pricey OEM optics in our Arista 7050SX3 switches with LS-MM8525E-S1C. EEPROM coding was spot on and link came up in dual-rate 10/25Gbps mode immediately. Will reorder for next rack expansion. :-)

Bought a batch of 20 for our campus network upgrade across OM3 fiber. Recognized instantly by our Dell PowerSwitch S5248F-ON without any EEPROM override commands. DOM diagnostics show stable -2.1 dBm TX power. Excellent 25Gbps optical transceiver for the price. =D

Product works perfectly at 25Gbps on 850nm wavelength. Outer cardboard packaging had a minor crease upon delivery, but internal anti-static blister packs protected all 8 modules safely.

Plugged two of these LS-MM8525E-S1C SFP28 25GBASE-SR modules into our Cisco Catalyst 9500 switches on OM4 duplex LC fibers. Both links came up instantly at full 25Gbps line rate with clean optical power telemetry on DDM. Excellent build quality for enterprise aggregation.

Modules work fine on our Juniper EX4600 switches, but the plastic pull-tab latch felt a bit stiff when removing from a high-density switch panel. Otherwise zero packet loss on 70m OM3 fiber links.

We had a large volume for 10/25/40G Transceiver Modules each month.always had good performance. This time our Account Manager told me that it had a big price reduction, so we purchased some more which can be used for six months. Surprisingly, we received the goods quickly. That's great.
