Specifications

Cisco SFP-25G-ER Lite Compatible 25GBASE-ER SFP28 Optical Transceiver Module (SMF, 1310nm, 40km, LC, DDM)

The Cisco SFP-25G-ER lite compatible 25G SFP28 transceiver module is equipped with LC duplex connectors, reaching a link up to 40km over OS2 single-mode fiber with FEC (30km over G.652 SMF without FEC). This 25G optical transceiver comes with an SFP28 connector, enabling 25 Gbps bandwidth. DOM/DDM (digital diagnostics monitoring) function is supported on the 25G fiber optic transceiver to achieve real-time operating parameters monitoring.

QSFPTEK manufactured 25GBASE-ER SFP28 module is compliant with SFP28 MSA, IEEE 802.3by SFP28 specifications. Besides, the small form-factor pluggable 28 (SFP28) ER optic has been tested on host devices to ensure full compatibility with Cisco equipment, such as data center switches, enterprise routers, and server network interface cards (NICs). The third-party 25G SFP module is an ideal substitute to the Cisco SFP-25G-ER SFP28 25G transceiver at an affordable price, providing a cost-effective compatible solution for high-performance 25G connectivity.

ER 25G SFP28 transceiver caters to 25 Gigabit Ethernet (25GbE) optical fiber connections, ideal for long-distance applications in the campus, metro networks, ISP operators, etc.

Questions & Answers

Can this 25G transceiver run at 10G? On your product page, I see it is connected with OM3/OM4 cables, but I only have OM2 cables, can I use OM2 directly?

I'm sorry. It can only work at 25Gbps. However, you can use the OM2 cables to connect this 25G transceiver, but pls know the transmission distance would be less than 100m over OM2 cables.
Is it compatible with my Cisco C9500 series switch?

You need to check whether the device is equipped with sfp28 ports or not by youself. Or tell us the specific switch model name (like C9500-48Y-4C) and then we'll check it for you. If the swich has bulit-in sfp28 ports, there will be no issue.
Have undergone any test programs? If yes, what are they?

This module usually has the following tests: Normal/High Temperature Testing, Power Testing, Eye Diagram Testing, Sensitivity Testing, DDM Monitoring and Ping Package Testing.

To uplink the EX4400-EM-4Y switch SFP28 port to the data center EX4650 switch qsfp28 port, I threw these 25g SRs for a 4x 25G to 100G connection. They seem to work fine (at least so far) with the switch port, harness cable, and the 100G module on the other end.

wanner a few 25g sr and 10m om4 fibers for my project. They lost the fiber patch cable order for they didn't offer a free shipping service for the cable items. still bought 4 sfp28 sr for a try. As for the performance, currently not working long enough, I will not express any opinions for the time being. maybe i will evaluate it in a few months.

there is a multi-gig switch in our enterprise network. this dual rate sr exactly matches my requirement for consideration of network upgrade. Tested on both 10G port and 25G uplink, works fine.

shop from here after doing research on several SFP manufacturers. Impressed by the price offered. currently works fine with my Cisco switch. I do get a cheaper price from other vendors, but maybe they have refurbished modules.

I got a C9200L-24PXG-2Y as an aggregation switch in my server room, I find it works well with the 25g lr over my os2 smf. Maybe review later again if there are any issues.

Nice price, works with no issue so far. My company needs to purchase dozens 25g sr to replace the old one for they've been used for over 5 years and optical fiber link fails occurs more frequently than ever. I know QSFPTEK from their ads and am interested in the price. At first, I feel it's not so convenient as the live chat is not live and they don't provide online shopping. However, their sale contacts me the next day with the detailed info I required. Finally, I won a business discount for my project. can’t help but think back, if I placed an order directly the night before, I might not be able to get this discount. haha
