CWDM XFP Transceivers


XFP CWDM optics are based on the XFP form factor which is an MSA standard build. The maximum speed these optics are capable of is 11.25G and are commonly used in 10G Ethernet. This form factor is also used for OC192 and 8x Fiber channel.

This CWDM version emits light which is defined in the CWDM specification. The CWDM ITU grid is defined from 1270 to 1610nm and has steps of 20nm. So the available wavelengths are: 1270nm, 1290nm, 1310nm, 1330nm, 1350nm, 1370nm, 1390nm, 1410nm, 1430nm, 1450nm, 1470nm, 1490nm, 1510nm, 1530nm, 1550nm, 1570nm, 1590nm and 1610nm.

The official naming defined by the MSA community is: 1271nm, 1291nm, 1311nm, 1331nm, 1351nm, 1371nm, 1391nm, 1411nm, 1431nm, 1451nm, 1471nm, 1491nm, 1511nm, 1531nm, 1551nm, 1571nm, 1591nm and 1611nm but in the industry the naming ending with the “0” is mostly adopted.

The XFP CWDM comes in 3 variations: LR, ER and ZR. Where the LR has 10dB power budget, the ER has 15dB and ZR 24db.   Because the channels between 1470 and 1610 are the most used, these channels come as LR, ER and ZR. The channels below 1470 come only in LR and ER.

In summary:
LR/10dB: 1270-1610nm
ER/15dB:1270-1610nm
ZR/24dB:1470-1610nm

The naming convention we use is quite straight forward. We start with the build which is XFP, followed the color, then the strength and we end with “-SO” for Solid Optics. So for example XFP-CWDM1570-ZR-SO

The distance you can reach with the dB is dependent on the color or nanometer used. Also the mux type and fiber quality are an important factor in this. We can help you with calculating the power budget of your project.

These XFP CWDM optics are Solid Optics own products which are not offered by the router/switch manufacturers. Please be sure to purchase this type optic from companies who specialize in optical transceivers like Solid Optics. We can supply these optics compatible with almost every brand.

Many manufacturers optics are supplied with vendor locking and only with the proper coding. Solid optics specializes in the "re-branding" or re-coding of optical transceivers. In our testing facility we test all our optics coding on Switches and Routers from all the major brands like Cisco, HP, H3C, Juniper, Huawei, Brocade, Arista etc.

All our optics are individually tested in our test lab in the Netherlands where we test on traffic, color, compatibility, EEPROM content and after testing we inspect the lenses to ensure there are no irregularities.

We can also provide you with a Solid Optics "Multi-Fiber-Tool" to recode the optics yourself, on site in conjunction with a web or Android apps.

If you have any questions, please don't hesitate to ask us for more information on compatibility.
