A:
One part number is fine, but the 20km link will need a pad. At 20km the loss is typically only 6 to 7dB, which puts the receiver close to its overload point of about -1dBm. Fit a 10dB attenuator there and keep the 66km run as it is. Measure both ends after installation and keep receive power between -8 and -18dBm. By
admin
A:
Yes, the same optical design is available in a -40 to 85C industrial variant, which is the right choice for unventilated outdoor cabinets. For cabinets that stay under about 60C internally, the commercial 0 to 70C part here is normally sufficient. Tell us the cabinet conditions when ordering and we will confirm the correct model. By
admin
A:
Yes. The link is transparent to Ethernet frames, including jumbo frames, so video traffic behaves the same as any other 1G stream. At 60km with typical splice loss the receive level usually lands around -18 to -20dBm, well inside the -26dBm sensitivity. We recommend enabling storm control on the camera VLAN rather than relying on the optic for traffic shaping. By
admin
A:
Yes, provided the mux has a 1510 port on the standard 20nm CWDM grid. 1490 and 1510 are adjacent channels, so isolation matters, use a mux with good adjacent channel isolation and keep the connector end faces clean. If your shelf is a combined 1490/1510 wideband port, you will need to move to a channelized mux. By
admin
A:
Optically they are very close, both are DFB based with -26dBm sensitivity and 80km reach. The difference is channel planning. Pick whichever CWDM channel is free on your mux, and if both are free, 1550 is more common and easier to source spares for. For a 50km span either one leaves plenty of margin. By
admin
I manage the optical layer for a mid size enterprise and these are part of our CWDM standard. The 1510nm channel is used for backup paths, so they sit idle most of the time and get exercised during failover tests. They come up every time without renegotiation issues. My only note is the datasheet could state minimum attenuation guidance for short spans more clearly.

Good long distance SFP for enterprise use. The DFB laser keeps power steady and the PIN receiver had no trouble with a span that includes six splices and two patch panels.

Nice that the wavelength is printed clearly on the label. In a CWDM shelf with eight channels mis-cabling is a real risk, so that detail helps during maintenance.

This is our standard 1510nm spare now. We keep eight on the shelf because pulling a new fibre pair is not an option on our routes. What I like is consistency between batches, the last two orders had TX power within 0.5dB of each other, so we do not have to re-baseline alarm thresholds every time we swap a module.

These 80km CWDM SFPs work well in our utility substation network. The 1510nm channel sits next to our 1470 and 1490 services with no interference on the mux.

Deployed for a factory to warehouse link at 47km, carrying voice, CCTV and ERP replication traffic on a trunked 1G. The link has been up 99.99 percent over a quarter. The metal cage seats firmly in our industrial switches and the LC connectors lock positively. For an 80km CWDM SFP the build quality is better than I expected.

Our substation telemetry uses these on a 66km single mode run with two intermediate splice boxes. The 1510nm channel is separated from our 1470nm SCADA link by a passive mux and we have seen no cross channel issues. Bit error testing at 1.25G ran clean for 48 hours. The modules report bias current and temperature properly, which our remote monitoring depends on.

Optics work fine on our 55km link, but the box arrived dented and the foam inside was crushed. One module had a scratch on the housing. No functional problem, just disappointing packaging for an export order.

Used as a 1G link between two factories on the same industrial estate, about 18km. We added a 10dB pad because the span was short, and everything has been stable since.

We ordered these to replace failing optics on an outdoor cabinet link. Temperature in the cabinet hits 50℃ in July and these have held without alarms, so the 0 to 70℃ rating is realistic.

We run a 6 channel CWDM backbone across a campus and 1510nm was allocated to the security network. These modules carry 40 IP camera streams and two access control links over 52km with no visible latency or frame loss. TX power sits at +1.6dBm and receive at -18.9dBm, so there is plenty of margin. Five months in, no DOM alarms and no flapping ports.

We used these for a long distance video surveillance project in a rural area. Cameras sit along a road with a fibre ring of about 70km and each node needs a stable 1G uplink. The 1510nm optics have handled temperature swings from 5℃ to 48℃ in the cabinets without dropping. DDM helped us spot a dirty connector at one node.
